A local, unprivileged user\ncould use this flaw to crash the system or leak kernel memory to user\nspace. (CVE-2016-0774, Moderate)\n\nThe security impact of this issue was discovered by Red Hat.\n\nThis update also fixes the following bugs:\n\n * In the anon_vma structure, the degree counts number of child anon_vmas\nand of VMAs which points to this anon_vma. Failure to decrement the\nparent's degree in the unlink_anon_vma() function, when its list was empty,\npreviously triggered a BUG_ON() assertion. The provided patch makes sure\nthe anon_vma degree is always decremented when the VMA list is empty, thus\nfixing this bug. (BZ#1318364)\n\n * When running Internet Protocol Security (IPSEC) on external storage\nencrypted with LUKS under a substantial load on the system, data\ncorruptions could previously occur. A set of upstream patches has been\nprovided, and data corruption is no longer reported in this situation.\n(BZ#1298994)\n\n * Due to prematurely decremented calc_load_task, the calculated load\naverage was off by up to the number of CPUs in the machine. As a\nconsequence, job scheduling worked improperly causing a drop in the system\nperformance. This update keeps the delta of the CPU going into NO_HZ idle\nseparately, and folds the pending idle delta into the global active count\nwhile correctly aging the averages for the idle-duration when leaving NO_HZ\nmode. Now, job scheduling works correctly, ensuring balanced CPU load.\n(BZ#1300349)\n\n * Due to a regression in the Red Hat Enterprise Linux 6.7 kernel, the\ncgroup OOM notifier accessed a cgroup-specific internal data structure\nwithout a proper locking protection, which led to a kernel panic. This\nupdate adjusts the cgroup OOM notifier to lock internal data properly,\nthus fixing the bug. (BZ#1302763)\n\n * GFS2 had a rare timing window that sometimes caused it to reference an\nuninitialized variable. Consequently, a kernel panic occurred. The code has\nbeen changed to reference the correct value during this timing window, and\nthe kernel no longer panics. (BZ#1304332)\n\n * Due to a race condition whereby a cache operation could be submitted\nafter a cache object was killed, the kernel occasionally crashed on systems\nrunning the cachefilesd service. The provided patch prevents the race\nconditio ...\n\n Description truncated, please see the referenced URL(s) for more information.\");\n script_tag(name:\"affected\", value:\"kernel on Red Hat Enterprise Linux Desktop (v. 6),\n Red Hat Enterprise Linux Server (v. 6),\n Red Hat Enterprise Linux Workstation (v. 6)\");\n script_tag(name:\"solution\", value:\"Please Install the Updated Packages.\");\n\n script_xref(name:\"RHSA\", value:\"2016:0494-01\");\n script_xref(name:\"URL\", value:\"https://www.redhat.com/archives/rhsa-announce/2016-March/msg00059.html\");\n script_tag(name:\"solution_type\", value:\"VendorFix\");\n script_category(ACT_GATHER_INFO);\n script_copyright(\"Copyright (C) 2016 Greenbone Networks GmbH\");\n script_family(\"Red Hat Local Security Checks\");\n script_dependencies(\"gather-package-list.nasl\");\n script_mandatory_keys(\"ssh/login/rhel\", \"ssh/login/rpms\", re:\"ssh/login/release=RHENT_6\");\n\n exit(0);\n}\n\ninclude(\"revisions-lib.inc\");\ninclude(\"pkg-lib-rpm.inc\");\n\nrelease = rpm_get_ssh_release();\nif(!release) exit(0);\n\nres = \"\";\n\nif(release == \"RHENT_6\")\n{\n\n if ((res = isrpmvuln(pkg:\"kernel\", rpm:\"kernel~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"kernel-debug\", rpm:\"kernel-debug~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"kernel-debug-debuginfo\", rpm:\"kernel-debug-debuginfo~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"kernel-debug-devel\", rpm:\"kernel-debug-devel~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"kernel-debuginfo\", rpm:\"kernel-debuginfo~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"kernel-debuginfo-common-i686\", rpm:\"kernel-debuginfo-common-i686~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"kernel-devel\", rpm:\"kernel-devel~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"kernel-headers\", rpm:\"kernel-headers~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"perf\", rpm:\"perf~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"perf-debuginfo\", rpm:\"perf-debuginfo~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"python-perf-debuginfo\", rpm:\"python-perf-debuginfo~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"kernel-abi-whitelists\", rpm:\"kernel-abi-whitelists~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"kernel-doc\", rpm:\"kernel-doc~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"kernel-firmware\", rpm:\"kernel-firmware~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"kernel-debuginfo-common-x86_64\", rpm:\"kernel-debuginfo-common-x86_64~2.6.32~573.22.1.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if (__pkg_match) exit(99);\n exit(0);\n}\n", "cvss": {"score": 7.2, "vector": "AV:L/AC:L/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2019-05-29T18:35:04", "bulletinFamily": "scanner", "cvelist": ["CVE-2016-0774", "CVE-2015-1805"], "description": "Check the version of kernel", "modified": "2019-03-08T00:00:00", "published": "2016-03-24T00:00:00", "id": "OPENVAS:1361412562310882433", "href": "http://plugins.openvas.org/nasl.php?oid=1361412562310882433", "type": "openvas", "title": "CentOS Update for kernel CESA-2016:0494 centos6", "sourceData": "###############################################################################\n# OpenVAS Vulnerability Test\n#\n# CentOS Update for kernel CESA-2016:0494 centos6\n#\n# Authors:\n# System Generated Check\n#\n# Copyright:\n# Copyright (C) 2016 Greenbone Networks GmbH, http://www.greenbone.net\n#\n# This program is free software; you can redistribute it and/or modify\n# it under the terms of the GNU General Public License version 2\n# (or any later version), as published by the Free Software Foundation.\n#\n# This program is distributed in the hope that it will be useful,\n# but WITHOUT ANY WARRANTY; without even the implied warranty of\n# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

(CVE-2016-0774, Moderate)\n\nThe security impact of this issue was discovered by Red Hat.\n\nThis update also fixes the following bugs:\n\n * In the anon_vma structure, the degree counts number of child anon_vmas\nand of VMAs which points to this anon_vma. Failure to decrement the\nparent's degree in the unlink_anon_vma() function, when its list was empty,\npreviously triggered a BUG_ON() assertion. The provided patch makes sure\nthe anon_vma degree is always decremented when the VMA list is empty, thus\nfixing this bug. (BZ#1318364)\n\n * When running Internet Protocol Security (IPSEC) on external storage\nencrypted with LUKS under a substantial load on the system, data\ncorruptions could previously occur. A set of upstream patches has been\nprovided, and data corruption is no longer reported in this situation.\n(BZ#1298994)\n\n * Due to prematurely decremented calc_load_task, the calculated load\naverage was off by up to the number of CPUs in the machine. As a\nconsequence, job scheduling worked improperly causing a drop in the system\nperformance. This update keeps the delta of the CPU going into NO_HZ idle\nseparately, and folds the pending idle delta into the global active count\nwhile correctly aging the averages for the idle-duration when leaving NO_HZ\nmode. Now, job scheduling works correctly, ensuring balanced CPU load.\n(BZ#1300349)\n\n * Due to a regression in the Red Hat Enterprise Linux 6.7 kernel, the\ncgroup OOM notifier accessed a cgroup-specific internal data structure\nwithout a proper locking protection, which led to a kernel panic. This\nupdate adjusts the cgroup OOM notifier to lock internal data properly,\nthus fixing the bug. (BZ#1302763)\n\n * GFS2 had a rare timing window that sometimes caused it to reference an\nuninitialized variable. Consequently, a kernel panic occurred. The code has\nbeen changed to reference the correct value during this timing window, and\nthe kernel no longer panics. (BZ#1304332)\n\n * Due to a race condition whereby a cache operation could be submitted\nafter a cache object was killed, the kernel occasionally crashed on systems\nrunning the cachefilesd service. The provided patch prevents the race\ncondition by adding serialization in the code that makes the object\nunavailable.

With this update,\nlpfc_device_reset_handler recovers storage without crashing. (BZ#1070964)\n\n * Due to the code decrementing the reclaim_in_progress counter without\nhaving incremented it first, severe spinlock contention occurred in the\nshrink_zone() function even though the vm.max_reclaims_in_progress feature\nwas set to 1. This update provides a patch fixing the underlying source\ncode, and spinlock contention no longer occurs in this scenario.\n(BZ#1164105)\n\n * A TCP socket using SACK that had a retransmission but recovered from it,\nfailed to reset the retransmission timestamp.

With this update, the socket clears retrans_stamp\nwhen the recovery is completed, thus fixing the bug. (BZ#1205521)\n\n * Previously, the signal delivery paths did not clear the TS_USEDFPU flag,\nwhich could cause problems in the switch_to() function and lead to\nfloating-point unit (FPU) corruption. With this update, TS_USEDFPU is\ncleared as expected, and FPU is no longer under threat of corruption.\n(BZ#1193505)\n\n * A race condition in the exit_sem() function previously caused the\nsemaphore undo list corruption.

A local, unprivileged user\ncould use this flaw to crash the system or leak kernel memory to user\nspace. (CVE-2016-0774, Moderate)\n\nThe security impact of this issue was discovered by Red Hat.\n\nThis update also fixes the following bugs:\n\n* In the anon_vma structure, the degree counts number of child anon_vmas\nand of VMAs which points to this anon_vma. Failure to decrement the\nparent's degree in the unlink_anon_vma() function, when its list was empty,\npreviously triggered a BUG_ON() assertion. The provided patch makes sure\nthe anon_vma degree is always decremented when the VMA list is empty, thus\nfixing this bug. (BZ#1318364)\n\n* When running Internet Protocol Security (IPSEC) on external storage\nencrypted with LUKS under a substantial load on the system, data\ncorruptions could previously occur. A set of upstream patches has been\nprovided, and data corruption is no longer reported in this situation.\n(BZ#1298994)\n\n* Due to prematurely decremented calc_load_task, the calculated load\naverage was off by up to the number of CPUs in the machine. As a\nconsequence, job scheduling worked improperly causing a drop in the system\nperformance. This update keeps the delta of the CPU going into NO_HZ idle\nseparately, and folds the pending idle delta into the global active count\nwhile correctly aging the averages for the idle-duration when leaving NO_HZ\nmode. Now, job scheduling works correctly, ensuring balanced CPU load.\n(BZ#1300349)\n\n* Due to a regression in the Red Hat Enterprise Linux 6.7 kernel, the\ncgroup OOM notifier accessed a cgroup-specific internal data structure\nwithout a proper locking protection, which led to a kernel panic. This\nupdate adjusts the cgroup OOM notifier to lock internal data properly,\nthus fixing the bug. (BZ#1302763)\n\n* GFS2 had a rare timing window that sometimes caused it to reference an\nuninitialized variable. Consequently, a kernel panic occurred. The code has\nbeen changed to reference the correct value during this timing window, and\nthe kernel no longer panics. (BZ#1304332)\n\n* Due to a race condition whereby a cache operation could be submitted\nafter a cache object was killed, the kernel occasionally crashed on systems\nrunning the cachefilesd service. The provided patch prevents the race\ncondition by adding serialization in the code that makes the object\nunavailable. As a result, all subsequent operations targetted on the object\nare rejected and the kernel no longer crashes in this scenario.\n(BZ#1308471)\n\nThis update also adds this enhancement:\n\n* The lpfc driver has been updated to version 11.0.0.4. (BZ#1297838)\n\nAll kernel users are advised to upgrade to these updated packages, which\ncontain backported patches to correct these issues and add this\nenhancement. The system must be rebooted for this update to take effect.\n\n\n**Merged security bulletin from advisories:**\nhttp://lists.centos.org/pipermail/centos-announce/2016-March/033807.html\n\n**Affected packages:**\nkernel\nkernel-abi-whitelists\nkernel-debug\nkernel-debug-devel\nkernel-devel\nkernel-doc\nkernel-firmware\nkernel-headers\nperf\npython-perf\n\n**Upstream details at:**\nhttps://rhn.redhat.com/errata/RHSA-2016-0494.html", "edition": 3, "modified": "2016-03-23T13:20:33", "published": "2016-03-23T13:20:33", "href": "http://lists.centos.org/pipermail/centos-announce/2016-March/033807.html", "id": "CESA-2016:0494", "title": "kernel, perf, python security update", "type": "centos", "cvss": {"score": 7.2, "vector": "AV:L/AC:L/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2019-12-20T18:26:15", "bulletinFamily": "unix", "cvelist": ["CVE-2015-1805"], "description": "**CentOS Errata and Security Advisory** CESA-2015:1042\n\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system.\n\n* It was found that the Linux kernel's implementation of vectored pipe read\nand write functionality did not take into account the I/O vectors that were\nalready processed when retrying after a failed atomic access operation,\npotentially resulting in memory corruption due to an I/O vector array\noverrun. A local, unprivileged user could use this flaw to crash the system\nor, potentially, escalate their privileges on the system. (CVE-2015-1805,\nImportant)\n\nThe security impact of this issue was discovered by Red Hat.\n\nThis update fixes the following bugs:\n\n* Due to a bug in the lpfc_device_reset_handler() function, a scsi command\ntimeout could lead to a system crash. With this update,\nlpfc_device_reset_handler recovers storage without crashing. (BZ#1070964)\n\n* Due to the code decrementing the reclaim_in_progress counter without\nhaving incremented it first, severe spinlock contention occurred in the\nshrink_zone() function even though the vm.max_reclaims_in_progress feature\nwas set to 1. This update provides a patch fixing the underlying source\ncode, and spinlock contention no longer occurs in this scenario.\n(BZ#1164105)\n\n* A TCP socket using SACK that had a retransmission but recovered from it,\nfailed to reset the retransmission timestamp. As a consequence, on certain\nconnections, if a packet had to be re-transmitted, the retrans_stamp\nvariable was only cleared when the next acked packet was received.\nThis could lead to an early abortion of the TCP connection if this next\npacket also got lost. With this update, the socket clears retrans_stamp\nwhen the recovery is completed, thus fixing the bug. (BZ#1205521)\n\n* Previously, the signal delivery paths did not clear the TS_USEDFPU flag,\nwhich could cause problems in the switch_to() function and lead to\nfloating-point unit (FPU) corruption. With this update, TS_USEDFPU is\ncleared as expected, and FPU is no longer under threat of corruption.\n(BZ#1193505)\n\n* A race condition in the exit_sem() function previously caused the\nsemaphore undo list corruption. As a consequence, a kernel crash could\noccur. The corruption in the semaphore undo list has been fixed, and the\nkernel no longer crashes in this situation.

Linux\noperating system.\n\n* It was found that the fix for CVE-2015-1805 incorrectly kept buffer\noffset and buffer length in sync on a failed atomic read, potentially\nresulting in a pipe buffer state corruption. A local, unprivileged user\ncould use this flaw to crash the system or leak kernel memory to user\nspace. (CVE-2016-0774, Moderate)\n\nThe security impact of this issue was discovered by Red Hat.\n\nThis update also fixes the following bugs:\n\n* In the anon_vma structure, the degree counts number of child anon_vmas\nand of VMAs which points to this anon_vma. Failure to decrement the\nparent's degree in the unlink_anon_vma() function, when its list was empty,\npreviously triggered a BUG_ON() assertion. The provided patch makes sure\nthe anon_vma degree is always decremented when the VMA list is empty, thus\nfixing this bug. (BZ#1318364)\n\n* When running Internet Protocol Security (IPSEC) on external storage\nencrypted with LUKS under a substantial load on the system, data\ncorruptions could previously occur. A set of upstream patches has been\nprovided, and data corruption is no longer reported in this situation.\n(BZ#1298994)\n\n* Due to prematurely decremented calc_load_task, the calculated load\naverage was off by up to the number of CPUs in the machine. As a\nconsequence, job scheduling worked improperly causing a drop in the system\nperformance. This update keeps the delta of the CPU going into NO_HZ idle\nseparately, and folds the pending idle delta into the global active count\nwhile correctly aging the averages for the idle-duration when leaving NO_HZ\nmode. Now, job scheduling works correctly, ensuring balanced CPU load.\n(BZ#1300349)\n\n* Due to a regression in the Red Hat Enterprise Linux 6.7 kernel, the\ncgroup OOM notifier accessed a cgroup-specific internal data structure\nwithout a proper locking protection, which led to a kernel panic. This\nupdate adjusts the cgroup OOM notifier to lock internal data properly,\nthus fixing the bug. (BZ#1302763)\n\n* GFS2 had a rare timing window that sometimes caused it to reference an\nuninitialized variable. Consequently, a kernel panic occurred. The code has\nbeen changed to reference the correct value during this timing window, and\nthe kernel no longer panics. (BZ#1304332)\n\n* Due to a race condition whereby a cache operation could be submitted\nafter a cache object was killed, the kernel occasionally crashed on systems\nrunning the cachefilesd service. The provided patch prevents the race\ncondition by adding serialization in the code that makes the object\nunavailable. As a result, all subsequent operations targetted on the object\nare rejected and the kernel no longer crashes in this scenario.\n(BZ#1308471)\n\nThis update also adds this enhancement:\n\n* The lpfc driver has been updated to version 11.0.0.4.

(CVE-2016-0774, Moderate)\n\nRed Hat would like to thank the Perception Point research team for\nreporting the CVE-2016-0728 issue. The security impact of the CVE-2016-0774\nissue was discovered by Red Hat.\n\nBug fixes:\n\n* NMI watchdog of guests using legacy LVT0-based NMI delivery did not work\nwith APICv. Now, NMI works with LVT0 regardless of APICv. (BZ#1244726)\n\n* Parallel file-extending direct I/O writes could previously race to update\nthe size of the file. If they executed out-of-order, the file size could\nmove backwards and push a previously completed write beyond the end of the\nfile, causing it to be lost. (BZ#1258942)\n\n* The GHES NMI handler had a global spin lock that significantly increased\nthe latency of each perf sample collection. This update simplifies locking\ninside the handler. (BZ#1280200)\n\n* Sometimes, iptables rules are updated along with ip rules, and routes are\nreloaded. Previously, skb->sk was mistakenly attached to some IPv6\nforwarding traffic packets, which could cause kernel panic. Now, such\npackets are checked and not processed. (BZ#1281700)\n\n* The NUMA node was not reported for PCI adapters, which affected every\nPOWER system deployed with Red Hat Enterprise Linux 7 and caused\nsignificant decrease in the system performance. (BZ#1283525)\n\n* Processing packets with a lot of different IPv6 source addresses caused\nthe kernel to return warnings concerning soft-lockups due to high lock\ncontention and latency increase. (BZ#1285369)\n\n* Running edge triggered interrupts with an ack notifier when\nsimultaneously reconfiguring the Intel I/O IOAPIC did not work correctly,\nso EOI in the interrupt did not cause a VM to exit if APICv was enabled.\nConsequently, the VM sometimes became unresponsive. (BZ#1287001)\n\n* Block device readahead was artificially limited, so the read performance\nwas poor, especially on RAID devices. Now, per-device readahead limits are\nused for each device, which has improved read performance. (BZ#1287548)\n\n* Identical expectations could not be tracked simultaneously even if they\nresided in different connection tracking zones. Now, an expectation insert\nattempt is rejected only if the zone is also identical. (BZ#1290093)\n\n* The storvsc kernel driver for Microsoft Hyper-V storage was setting\nincorrect SRB flags, and Red Hat Enterprise Linux 7 guests running on\nMicrosoft Hyper-V were experiencing slow I/O as well as I/O failures when\nthey were connected to a virtual SAN. Now, SRB flags are set correctly.\n(BZ#1290095)\n\n* When a NUMA system with no memory in node 0 was used, the system\nterminated unexpectedly during boot or when using OpenVSwitch. Now, the\nkernel tries to allocate memory from other nodes when node 0 is not\npresent. (BZ#1300950)\n\nEnhancement:\n\n* IPsec has been updated to provide many fixes and some enhancements.\nOf particular note is the ability to match on outgoing interfaces.\n(BZ#1287407)", "modified": "2016-04-04T19:57:06", "published": "2016-02-02T21:05:39", "id": "RHSA-2016:0103", "href": "https://access.redhat.com/errata/RHSA-2016:0103", "type": "redhat", "title": "(RHSA-2016:0103) Important: kernel security, bug fix, and enhancement update", "cvss": {"score": 7.2, "vector": "AV:L/AC:L/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2019-08-13T18:44:44", "bulletinFamily": "unix", "cvelist": ["CVE-2015-1805"], "description": "The kernel packages contain the Linux kernel, the core of any Linux\noperating system.\n\n* It was found that the Linux kernel's implementation of vectored pipe read\nand write functionality did not take into account the I/O vectors that were\nalready processed when retrying after a failed atomic access operation,\npotentially resulting in memory corruption due to an I/O vector array\noverrun.

(CVE-2015-1805,\nImportant)\n\nThe security impact of this issue was discovered by Red Hat.\n\nThis update fixes the following bugs:\n\n* Due to a bug in the lpfc_device_reset_handler() function, a scsi command\ntimeout could lead to a system crash. With this update,\nlpfc_device_reset_handler recovers storage without crashing. (BZ#1070964)\n\n* Due to the code decrementing the reclaim_in_progress counter without\nhaving incremented it first, severe spinlock contention occurred in the\nshrink_zone() function even though the vm.max_reclaims_in_progress feature\nwas set to 1. This update provides a patch fixing the underlying source\ncode, and spinlock contention no longer occurs in this scenario.\n(BZ#1164105)\n\n* A TCP socket using SACK that had a retransmission but recovered from it,\nfailed to reset the retransmission timestamp. As a consequence, on certain\nconnections, if a packet had to be re-transmitted, the retrans_stamp\nvariable was only cleared when the next acked packet was received.\nThis could lead to an early abortion of the TCP connection if this next\npacket also got lost. With this update, the socket clears retrans_stamp\nwhen the recovery is completed, thus fixing the bug. (BZ#1205521)\n\n* Previously, the signal delivery paths did not clear the TS_USEDFPU flag,\nwhich could cause problems in the switch_to() function and lead to\nfloating-point unit (FPU) corruption. With this update, TS_USEDFPU is\ncleared as expected, and FPU is no longer under threat of corruption.\n(BZ#1193505)\n\n* A race condition in the exit_sem() function previously caused the\nsemaphore undo list corruption. As a consequence, a kernel crash could\noccur. The corruption in the semaphore undo list has been fixed, and the\nkernel no longer crashes in this situation. (BZ#1124574)\n\n* Previously, when running the \"virsh blockresize [Device] [Newsize]\"\ncommand to resize the disk, the new size was not reflected in a Red Hat\nEnterprise Linux 5 Virtual Machine (VM). With this update, the new size is\nnow reflected online immediately in a Red Hat Enterprise Linux 5 VM so it\nis no longer necessary to reboot the VM to see the new disk size.\n(BZ#1200855)\n\nAll kernel users are advised to upgrade to these updated packages, which\ncontain backported patches to correct these issues.

A Common Vulnerability Scoring System (CVSS) base\nscore, which gives a detailed severity rating, is available from the\nCVE link in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system.\n\n* It was found that the fix for CVE-2015-1805 incorrectly kept buffer\noffset and buffer length in sync on a failed atomic read, potentially\nresulting in a pipe buffer state corruption. A local, unprivileged\nuser could use this flaw to crash the system or leak kernel memory to\nuser space. (CVE-2016-0774, Moderate)\n\nThe security impact of this issue was discovered by Red Hat.\n\nThis update also fixes the following bugs :\n\n* In the anon_vma structure, the degree counts number of child\nanon_vmas and of VMAs which points to this anon_vma. Failure to\ndecrement the parent's degree in the unlink_anon_vma() function, when\nits list was empty, previously triggered a BUG_ON() assertion. The\nprovided patch makes sure the anon_vma degree is always decremented\nwhen the VMA list is empty, thus fixing this bug. (BZ#1318364)\n\n* When running Internet Protocol Security (IPSEC) on external storage\nencrypted with LUKS under a substantial load on the system, data\ncorruptions could previously occur. A set of upstream patches has been\nprovided, and data corruption is no longer reported in this situation.\n(BZ#1298994)\n\n* Due to prematurely decremented calc_load_task, the calculated load\naverage was off by up to the number of CPUs in the machine. As a\nconsequence, job scheduling worked improperly causing a drop in the\nsystem performance. This update keeps the delta of the CPU going into\nNO_HZ idle separately, and folds the pending idle delta into the\nglobal active count while correctly aging the averages for the\nidle-duration when leaving NO_HZ mode. Now, job scheduling works\ncorrectly, ensuring balanced CPU load. (BZ#1300349)\n\n* Due to a regression in the Red Hat Enterprise Linux 6.7 kernel, the\ncgroup OOM notifier accessed a cgroup-specific internal data structure\nwithout a proper locking protection, which led to a kernel panic. This\nupdate adjusts the cgroup OOM notifier to lock internal data properly,\nthus fixing the bug. (BZ#1302763)\n\n* GFS2 had a rare timing window that sometimes caused it to reference\nan uninitialized variable. Consequently, a kernel panic occurred. The\ncode has been changed to reference the correct value during this\ntiming window, and the kernel no longer panics. (BZ#1304332)\n\n* Due to a race condition whereby a cache operation could be submitted\nafter a cache object was killed, the kernel occasionally crashed on\nsystems running the cachefilesd service. The provided patch prevents\nthe race condition by adding serialization in the code that makes the\nobject unavailable. As a result, all subsequent operations targetted\non the object are rejected and the kernel no longer crashes in this\nscenario. (BZ#1308471)\n\nThis update also adds this enhancement :\n\n* The lpfc driver has been updated to version 11.0.0.4. (BZ#1297838)\n\nAll kernel users are advised to upgrade to these updated packages,\nwhich contain backported patches to correct these issues and add this\nenhancement. The system must be rebooted for this update to take\neffect.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://access.redhat.com/errata/RHSA-2016:0494\"\n );\n

A local, unprivileged user could use\n this flaw to crash the system or leak kernel memory to\n user space. (CVE-2016-0774, Moderate)\n\nThis update also fixes the following bugs :\n\n - In the anon_vma structure, the degree counts number of\n child anon_vmas and of VMAs which points to this\n anon_vma. Failure to decrement the parent's degree in\n the unlink_anon_vma() function, when its list was empty,\n previously triggered a BUG_ON() assertion. The provided\n patch makes sure the anon_vma degree is always\n decremented when the VMA list is empty, thus fixing this\n bug.\n\n - When running Internet Protocol Security (IPSEC) on\n external storage encrypted with LUKS under a substantial\n load on the system, data corruptions could previously\n occur. A set of upstream patches has been provided, and\n data corruption is no longer reported in this situation.\n\n - Due to prematurely decremented calc_load_task, the\n calculated load average was off by up to the number of\n CPUs in the machine. As a consequence, job scheduling\n worked improperly causing a drop in the system\n performance. This update keeps the delta of the CPU\n going into NO_HZ idle separately, and folds the pending\n idle delta into the global active count while correctly\n aging the averages for the idle-duration when leaving\n NO_HZ mode. Now, job scheduling works correctly,\n ensuring balanced CPU load.\n\n - Due to a regression in the Scientific Linux 6.7 kernel,\n the cgroup OOM notifier accessed a cgroup-specific\n internal data structure without a proper locking\n protection, which led to a kernel panic. This update\n adjusts the cgroup OOM notifier to lock internal data\n properly, thus fixing the bug.\n\n - GFS2 had a rare timing window that sometimes caused it\n to reference an uninitialized variable. Consequently, a\n kernel panic occurred. The code has been changed to\n reference the correct value during this timing window,\n and the kernel no longer panics.\n\n - Due to a race condition whereby a cache operation could\n be submitted after a cache object was killed, the kernel\n occasionally crashed on systems running the cachefilesd\n service. The provided patch prevents the race condition\n by adding serialization in the code that makes the\n object unavailable. As a result, all subsequent\n operations targetted on the object are rejected and the\n kernel no longer crashes in this scenario.\n\nThis update also adds this enhancement :\n\n - The lpfc driver has been updated to version 11.0.0.4.\n\nThe system must be rebooted for this update to take effect.\"\n );\n # https://listserv.fnal.gov/scripts/wa.exe?A2=ind1603&L=scientific-linux-errata&F=&S=&P=12268\n script_set_attribute(\n attribute:\"see_also\",\n value:\"http://www.nessus.org/u?0f8c97a4\"\n );\n script_set_attribute(attribute:\"solution\", value:\"Update the affected packages.\");\n script_set_cvss_base_vector(\"CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C\");\n script_set_cvss_temporal_vector(\"CVSS2#E:H/RL:OF/RC:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H\");\n script_set_cvss3_temporal_vector(\"CVSS:3.0/E:H/RL:O/RC:C\");\n script_set_attribute(attribute:\"exploitability_ease\", value:\"Exploits are available\");\n script_set_attribute(attribute:\"exploit_available\", value:\"true\");\n script_set_attribute(attribute:\"exploited_by_malware\", value:\"true\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-abi-whitelists\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debug\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debug-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debug-devel\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debuginfo-common-i686\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debuginfo-common-x86_64\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-devel\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-doc\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-firmware\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-headers\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:perf\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:perf-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:python-perf\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:python-perf-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"x-cpe:/o:fermilab:scientific_linux\");\n\n script_set_attribute(attribute:\"vuln_publication_date\", value:\"2015/08/08\");\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2016/03/23\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2016/03/24\");\n script_set_attribute(attribute:\"generated_plugin\", value:\"current\");\n script_end_attributes();\n\n script_category(ACT_GATHER_INFO);\n script_copyright(english:\"This script is Copyright (C) 2016-2021 and is owned by Tenable, Inc. or an Affiliate thereof.\");\n script_family(english:\"Scientific Linux Local Security Checks\");\n\n script_dependencies(\"ssh_get_info.nasl\");\n script_require_keys(\"Host/local_checks_enabled\", \"Host/cpu\", \"Host/RedHat/release\", \"Host/RedHat/rpm-list\");\n\n exit(0);\n}\n\n\ninclude(\"audit.inc\");\ninclude(\"global_settings.inc\");\ninclude(\"misc_func.inc\");\ninclude(\"rpm.inc\");\n\nif (!get_kb_item(\"Host/local_checks_enabled\")) audit(AUDIT_LOCAL_CHECKS_NOT_ENABLED);\nrelease = get_kb_item(\"Host/RedHat/release\");\nif (isnull(release) || \"Scientific Linux \" >!< release) audit(AUDIT_HOST_NOT, \"running Scientific Linux\");\nos_ver = pregmatch(pattern: \"Scientific Linux.*release ([0-9]+(\\.[0-9]+)?)\", string:release);\nif (isnull(os_ver)) audit(AUDIT_UNKNOWN_APP_VER, \"Scientific Linux\");\nos_ver = os_ver[1];\nif (!

Advisory 2016:0494 :\n\nUpdated kernel packages that fix one security issue, several bugs, and\nadd one enhancement are now available for Red Hat Enterprise Linux 6.\n\nRed Hat Product Security has rated this update as having Moderate\nsecurity impact. A Common Vulnerability Scoring System (CVSS) base\nscore, which gives a detailed severity rating, is available from the\nCVE link in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system.\n\n* It was found that the fix for CVE-2015-1805 incorrectly kept buffer\noffset and buffer length in sync on a failed atomic read, potentially\nresulting in a pipe buffer state corruption. A local, unprivileged\nuser could use this flaw to crash the system or leak kernel memory to\nuser space. (CVE-2016-0774, Moderate)\n\nThe security impact of this issue was discovered by Red Hat.\n\nThis update also fixes the following bugs :\n\n* In the anon_vma structure, the degree counts number of child\nanon_vmas and of VMAs which points to this anon_vma. Failure to\ndecrement the parent's degree in the unlink_anon_vma() function, when\nits list was empty, previously triggered a BUG_ON() assertion. The\nprovided patch makes sure the anon_vma degree is always decremented\nwhen the VMA list is empty, thus fixing this bug. (BZ#1318364)\n\n* When running Internet Protocol Security (IPSEC) on external storage\nencrypted with LUKS under a substantial load on the system, data\ncorruptions could previously occur. A set of upstream patches has been\nprovided, and data corruption is no longer reported in this situation.\n(BZ#1298994)\n\n* Due to prematurely decremented calc_load_task, the calculated load\naverage was off by up to the number of CPUs in the machine. As a\nconsequence, job scheduling worked improperly causing a drop in the\nsystem performance. This update keeps the delta of the CPU going into\nNO_HZ idle separately, and folds the pending idle delta into the\nglobal active count while correctly aging the averages for the\nidle-duration when leaving NO_HZ mode. Now, job scheduling works\ncorrectly, ensuring balanced CPU load. (BZ#1300349)\n\n* Due to a regression in the Red Hat Enterprise Linux 6.7 kernel, the\ncgroup OOM notifier accessed a cgroup-specific internal data structure\nwithout a proper locking protection, which led to a kernel panic. This\nupdate adjusts the cgroup OOM notifier to lock internal data properly,\nthus fixing the bug. (BZ#1302763)\n\n* GFS2 had a rare timing window that sometimes caused it to reference\nan uninitialized variable. Consequently, a kernel panic occurred. The\ncode has been changed to reference the correct value during this\ntiming window, and the kernel no longer panics. (BZ#1304332)\n\n* Due to a race condition whereby a cache operation could be submitted\nafter a cache object was killed, the kernel occasionally crashed on\nsystems running the cachefilesd service. The provided patch prevents\nthe race condition by adding serialization in the code that makes the\nobject unavailable. As a result, all subsequent operations targetted\non the object are rejected and the kernel no longer crashes in this\nscenario. (BZ#1308471)\n\nThis update also adds this enhancement :\n\n* The lpfc driver has been updated to version 11.0.0.4. (BZ#1297838)\n\nAll kernel users are advised to upgrade to these updated packages,\nwhich contain backported patches to correct these issues and add this\nenhancement.

The security impact of the\nCVE-2016-0774 issue was discovered by Red Hat.\n\nBug fixes :\n\n* NMI watchdog of guests using legacy LVT0-based NMI delivery did not\nwork with APICv. Now, NMI works with LVT0 regardless of APICv.\n(BZ#1244726)\n\n* Parallel file-extending direct I/O writes could previously race to\nupdate the size of the file. If they executed out-of-order, the file\nsize could move backwards and push a previously completed write beyond\nthe end of the file, causing it to be lost. (BZ#1258942)\n\n* The GHES NMI handler had a global spin lock that significantly\nincreased the latency of each perf sample collection. This update\nsimplifies locking inside the handler. (BZ#1280200)\n\n* Sometimes, iptables rules are updated along with ip rules, and\nroutes are reloaded. Previously, skb->sk was mistakenly attached to\nsome IPv6 forwarding traffic packets, which could cause kernel panic.\nNow, such packets are checked and not processed. (BZ#1281700)\n\n* The NUMA node was not reported for PCI adapters, which affected\nevery POWER system deployed with Red Hat Enterprise Linux 7 and caused\nsignificant decrease in the system performance. (BZ#1283525)\n\n* Processing packets with a lot of different IPv6 source addresses\ncaused the kernel to return warnings concerning soft-lockups due to\nhigh lock contention and latency increase. (BZ#1285369)\n\n* Running edge triggered interrupts with an ack notifier when\nsimultaneously reconfiguring the Intel I/O IOAPIC did not work\ncorrectly, so EOI in the interrupt did not cause a VM to exit if APICv\nwas enabled. Consequently, the VM sometimes became unresponsive.\n(BZ#1287001)\n\n* Block device readahead was artificially limited, so the read\nperformance was poor, especially on RAID devices. Now, per-device\nreadahead limits are used for each device, which has improved read\nperformance. (BZ#1287548)\n\n* Identical expectations could not be tracked simultaneously even if\nthey resided in different connection tracking zones. Now, an\nexpectation insert attempt is rejected only if the zone is also\nidentical. (BZ#1290093)\n\n* The storvsc kernel driver for Microsoft Hyper-V storage was setting\nincorrect SRB flags, and Red Hat Enterprise Linux 7 guests running on\nMicrosoft Hyper-V were experiencing slow I/O as well as I/O failures\nwhen they were connected to a virtual SAN. Now, SRB flags are set\ncorrectly. (BZ#1290095)\n\n* When a NUMA system with no memory in node 0 was used, the system\nterminated unexpectedly during boot or when using OpenVSwitch.

Linux kernel that\nmay lead to a privilege escalation, denial of service, information leaks\nor data corruption.\n\nCVE-2015-1805\n\n Red Hat discovered that the pipe iovec read and write\n implementations may iterate over the iovec twice but will modify the\n iovec such that the second iteration accesses the wrong memory. A\n local user could use this flaw to crash the system or possibly for\n privilege escalation. This may also result in data corruption and\n information leaks in pipes between non-malicious processes.\n\nCVE-2015-3636\n\n Wen Xu and wushi of KeenTeam discovered that users allowed to create\n ping sockets can use them to crash the system and, on 32-bit\n architectures, for privilege escalation. However, by default, no\n users on a Debian system have access to ping sockets.\n\nCVE-2015-4167\n\n Carl Henrik Lunde discovered that the UDF implementation is missing\n a necessary length checks. A local user that can mount devices could\n use this flaw to crash the system.\n\nFor the oldstable distribution (wheezy), these problems have been fixed\nin version 3.2.68-1+deb7u2.\n\nFor the stable distribution (jessie), these problems were fixed in\nversion 3.16.7-ckt11-1 or earlier, except for CVE-2015-4167 which will\nbe fixed later.\n\nWe recommend that you upgrade your linux packages.\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n", "edition": 7, "modified": "2015-06-18T06:59:12", "published": "2015-06-18T06:59:12", "id": "DEBIAN:DSA-3290-1:2369A", "href": "https://lists.debian.org/debian-security-announce/debian-security-announce-2015/msg00186.html", "title": "[SECURITY] [DSA 3290-1] linux security update", "type": "debian", "cvss": {"score": 7.2, "vector": "AV:L/AC:L/Au:N/C:C/I:C/A:C"}}], "threatpost": [{"lastseen": "2018-10-06T22:55:36", "bulletinFamily": "info", "cvelist": ["CVE-2015-1805"], "description": "A rooting application has been found in the wild targeting Nexus mobile devices using a local privilege escalation vulnerability patched two years ago in the Linux kernel that remains unpatched in Android.\n\nResearchers at Zimperium, the same company that discovered last summer\u2019s Stagefright flaws affecting Android, privately disclosed to Google last Tuesday they found an application that had been used to root a Nexus 5 device. This news came a little less than a month after researchers at CORE Team reported to Google that [CVE-2015-1805](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-1805>), which was addressed in the Linux kernel in 2014, also affected Android devices.\n\nThe discovery of the rooting application\u2014Google said the exploit was not malicious\u2014prompted Google to push out emergency patches to its partners last Wednesday, and updates for Nexus devices. Partner patches are subject to carriers and handset manufacturers pushing the fixes to customer devices.\n\nGoogle said in an [advisory](<https://source.android.com/security/advisory/2016-03-18.html>) published last Friday that all Android devices on kernel versions 3.4, 3.10 and 3.14, including all Nexus devices are vulnerable. Android devices using Linux kernel version 3.18 or higher are not vulnerable.\n\n\u201cThis issue is rated as a critical severity issue due to the possibility of a local privilege escalation and arbitrary code execution leading to local permanent device compromise,\u201d Google said.\n\nRooting applications are particularly dangerous, not only because they are spread usually via Trojanized applications, but because they give their respective payloads system-level persistence.\n\nZimperium founder and CTO Zuk Avraham called the vulnerability being exploited by this particular rooting app \u201cquite generic,\u201d and said that it could be chained with other exploits to gain deeper penetration onto a device.\n\n\u201cIt allows for consistent elevation of privilege, so anyone with malicious intentions with code execution already on a device and wants higher code execution, could use it to get access to the microphone or camera, or read email, anything like that,\u201d Avraham said. \u201cBut you do need an initial code execution vulnerability or a presence on the device like an app for example. Then you can use this exploit, which is quite generic, and gain kernel privileges on the device.\u201d\n\nAvraham said this flaw was able to generate a payload on a device with a March 1, 2016 patch level, the most up to date patch level. He said the rooting app was spreading on an outside Android market away from Google\u2019s Google Play marketplace.\n\nGoogle said Google Play already blocks rooting applications by default, and that this particular rooting application if downloaded and manually installed from outside Google Play will also be blocked by Google\u2019s Verify Apps tool. Verify Apps, the former Bouncer, scans apps in Google Play for harmful behaviors and warns users not to install them if they\u2019re deemed dangerous.\n\n\u201cVerify Apps has been updated to block the installation of applications that we have learned are attempting to exploit this vulnerability both within and outside of Google Play,\u201d Google said in its advisory.\n\nSince rooting applications are banned from Google Play, an attacker would have to somehow convince a victim to manually install the app.\n\nGoogle said users can check the patch levels of their phone to determine whether they are vulnerable to these attacks; devices with a security patch level of March 18, 2016 or April 2, 2016 are not vulnerable, Google said.\n\nThis news comes days after the disclosure of new [exploits targeting vulnerabilities in libstagefright](<https://threatpost.com/stagefright-variant-metaphor-puts-millions-of-samsung-lg-and-htc-phones-at-risk/116870/>) called Metaphor, which uses malicious video files in two stages, to exploit Nexus 5, LG G3, HTC One and Samsung Galaxy S5 handsets.

The [Android Nexus Security Bulletin](<https://source.android.com/security/bulletin/index.html>) patches 15 vulnerabilities rated critical by Google in eight Android components, including Mediaserver and libstagefright.\n\nThe elevation of privilege bug exploited by the rooting application is the lone kernel-level flaw patched this month and it affects Nexus versions 4.4.4, 5.0.2, 5.1.1, 6.0 and 6.0.1. Google warned last month that exploits could lead to permanent device compromise.\n\nRooting applications are particularly dangerous because they give their respective payloads system-level persistence. Zimperium founder and CTO Zuk Avraham told Threatpost the vulnerability could be chained with other exploits to gain deeper penetration onto a device.\n\n\u201cIt allows for consistent elevation of privilege, so anyone with malicious intentions with code execution already on a device and wants higher code execution, could use it to get access to the microphone or camera, or read email, anything like that,\u201d Avraham said. \u201cBut you do need an initial code execution vulnerability or a presence on the device like an app for example. Then you can use this exploit, which is quite generic, and gain kernel privileges on the device.\u201d\n\nAs is becoming customary, the monthly Nexus security bulletins include fixes for critical Mediaserver and libstagefright vulnerabilities. Since the [Stagefright flaws](<https://threatpost.com/android-stagefright-flaws-put-950-million-devices-at-risk/113960/>) and exploits disclosed last summer during the Black Hat conference, researchers are taking a close look at this [core and privileged component of Android](<https://threatpost.com/stagefright-variant-metaphor-puts-millions-of-samsung-lg-and-htc-phones-at-risk/116870/>). Attackers can exploit these bugs using malicious media files to gain kernel access.\n\n\u201cIt\u2019s old code that\u2019s been there for a long time and it didn\u2019t go through as intense security testing as other pieces of Android,\u201d Zimperium\u2019s Avraham said. \u201cFor some researchers, it doesn\u2019t take much time to discover Stagefright vulnerabilities. If you have a device that\u2019s a few months old and want to target them with [malicious] MP4 files, it\u2019s relatively easy to find a vulnerability there. Every time you have a Stagefright bug and a kernel bug, an attacker can chain both and it\u2019s game over.\u201d\n\nToday\u2019s bulletin patches seven remote code execution bugs in Mediaserver, and one more in libstagefright. The update addresses memory corruption issues in both components.\n\n\u201cStagefright gives an attacker initial code execution,\u201d Avraham said. \u201cYou can send a link and trick the victim into opening it, or get man-in-the-middle and inject an iframe that shows the video, and once loaded\u2014without interaction\u2014the attacker gets initial code execution. To fully hack the device, chain it with a kernel exploit and at that point, you fully control the device.\u201d\n\nAlso patched today, three critical flaws in DHCPCD that open the door to remote code execution in the context of the DHCP client. The DHCP service, Google said, has privileges that third party applications would not.\n\nGoogle also patched a critical flaw in the Media Codec used by Mediaserver, which could be exploited by a crafted file to gain remote code execution.\n\nTwo Qualcomm components, the Qualcomm Performance Module and Qualcomm RF, were patched against elevation of privilege flaws. Both vulnerabilities could be exploited by malicious apps to execute code within the kernel.\n\nThe final critical vulnerability was patched in the common kernel and could also be exploited by a malicious app to gain remote code execution and permanent device compromise.\n\nGoogle also today patched 16 vulnerabilities it rates a \u201chigh\u201d severity, and eight others rated \u201cmoderate.\u201d\n", "modified": "2016-04-04T15:18:56", "published": "2016-04-04T14:00:22", "id": "THREATPOST:D28C91D0999C5EDFA9FCD89F6C95B17D", "href": "https://threatpost.com/google-patches-old-flaw-exploited-by-rooting-application/117161/", "type": "threatpost", "title": "April 2016 Google Android Nexus Security Bulletin", "cvss": {"score": 7.2, "vector": "AV:LOCAL/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}, {"lastseen": "2019-01-23T05:28:05", "bulletinFamily": "info", "cvelist": ["CVE-2014-3153", "CVE-2015-1805"], "description": "The Google Play Protect team said it identified a new strain of Android spyware called Tizi found inside several apps previously available via the Google Play marketplace. The recent discovery triggered a wider investigation by Google who said apps infected by the Tizi malware date back to 2015.\n\nRecent samples of Tizi allowed an attacker to root a targeted device and steal sensitive data from apps such as Facebook, Twitter, WhatsApp, Viber, Skype, LinkedIn and Telegram. Specific geographies targeted were Kenya, Nigeria and Tanzania, Google said. A smaller number of victims resided in the United States, researchers said.\n\n\u201cThe backdoor contains various capabilities common to commercial spyware, such as recording calls from WhatsApp, Viber, and Skype; sending and receiving SMS messages; and accessing calendar events, call log, contacts, photos, Wi-Fi encryption keys, and a list of all installed apps,\u201d researchers wrote in a [Google Security Blog post on Monday](<https://security.googleblog.com/2017/11/tizi-detecting-and-blocking-socially.html>).\n\nThe Tizi malware can also record ambient audio via the phone\u2019s microphone and silently take pictures with no on-screen notifications alerting the phone\u2019s owner.\n\n\u201cSubsequent command-and-control communications are normally performed over regular HTTPS, though in some specific versions, Tizi uses the MQTT messaging protocol with a custom server,\u201d Google said.\n\nGoogle Play Protect team said it discovered the spyware in September 2017, with the oldest sample dating back to October 2015. \u201cThe early Tizi variants didn\u2019t have rooting capabilities or obfuscation, but later variants did,\u201d researchers wrote.\n\n[](<https://media.threatpost.com/wp-content/uploads/sites/103/2017/11/06222051/Google_Infections_Tizi.png>)In total, Google said it identified 1,300 devices affected by Tizi.\n\nInitially Tizi was discovered on a workout app \u201ccom.dailyworkout.tizi\u201d that was promoted via social media and meant to appeal to fans of the Kenyan fitness brand Tizi. \u201cThe Tizi app developer also created a website and used social media to encourage more app installs from Google Play and third-party websites,\u201d Google said. Other Tizi-laced apps (com.press.nasa.com.tanofresh and com.system.update.systemupdate) were also found.\n\nResearchers said attackers mostly targeted users with older model Android phones running older chipsets and past versions of the Android OS. Targeted handsets did not have the most recent security patches from Google and were vulnerable to one of nine vulnerabilities that ranged from the Linux kernel vulnerability \u201cTowelRoot\u201d ([CVE-2014-3153](<https://threatpost.com/android-root-access-vulnerability-affecting-most-devices/106683/>)) to a rooting vulnerability ([CVE-2015-1805](<https://threatpost.com/google-patches-old-flaw-exploited-by-rooting-application/117161/>)) patched in 2014.\n\nAndroid devices with patch levels later than April 2016 are less exposed to Tizi\u2019s capabilities, researchers wrote.\n\n\u201cIf a Tizi app is unable to take control of a device because the vulnerabilities it tries to use are all patched, it will still attempt to perform some actions through the high level of permissions it asks the user to grant to it, mainly around reading and sending SMS messages and monitoring, redirecting, and preventing outgoing phone calls,\u201d wrote the Google Play Protect team.\n\nThis past year Google has made strides to shore up the Android ecosystem, from the Google Play marketplace to devices themselves.\n\nIn May, Google introduced Play Protect, a new security feature that maintains some oversight on content downloaded to Android devices. For example, previously downloaded apps can be continually scanned for malicious behaviors as a counter to developers who push benign apps to Google Play that later connect and download malicious components. This also helps provide a line of defense against apps downloaded from third-party stores that aren\u2019t subject to Google\u2019s malware scanners. Google said in May that Play Protect will be capable of scanning and verifying up to 50 billion apps on a daily basis.\n\nDespite those gains, reports of malware making it into Google\u2019s marketplace continue.\n\nEarlier this month Google [removed a phony adware-laced WhatsApp download](<https://threatpost.com/1m-downloads-later-google-pulls-phony-whatsapp-from-google-play/128778/>) from Google Play that was downloaded more than one million times. In March, Google booted more than a dozen apps from the Google Play store after [researchers discovered](<https://threatpost.com/adware-apps-booted-from-google-play/124549/>) each were rip-offs of legitimate apps and designed to aggressively push ads on Android devices. In August, [three messaging apps in the Google Play store](<https://threatpost.com/apps-infected-with-sonicspy-spyware-removed-from-google-play/127406/>) contained spyware called SonicSpy were also removed. And most recently, a flashlight app snuck BankBot malware into the Google Play store that stole banking credentials from victims.\n", "modified": "2017-11-28T12:40:09", "published": "2017-11-28T12:40:09", "id": "THREATPOST:5E0275127CA36073D1FD4B8A32CAADD6", "href": "https://threatpost.com/google-detects-and-boots-tizi-spyware-off-google-play/129012/", "type": "threatpost", "title": "Google Detects and Boots Tizi Spyware Off Google Play", "cvss": {"score": 7.2, "vector": "AV:LOCAL/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}], "ubuntu": [{"lastseen": "2020-07-02T11:38:50", "bulletinFamily": "unix", "cvelist": ["CVE-2015-4700", "CVE-2015-1805"], "description": "A flaw was discovered in the user space memory copying for the pipe iovecs \nin the Linux kernel.

However, the recent exploit can be used to bypass SELinux and plant backdoors. \n\n\n> \"We monitored six ZNIU rootkits, four of which were Dirty COW exploits. The other two were KingoRoot, a rooting app, and the Iovyroot exploit (CVE-2015-1805),\" the researchers said. \n\n> \"ZNIU used KingoRoot and Iovyroot because they can root ARM 32-bit CPU devices, which the rootkit for Dirty COW cannot.\"\n\n \n\n\n### Here's How the ZNIU's Dirty Cow exploit Works\n\n \n\n\n[](<https://3.bp.blogspot.com/-edAfrwmUa1o/WcpbZA19nhI/AAAAAAAAC1w/knqWT_NVbTcGjM3FcexOtFvRBbyMKiYoACLcBGAs/s1600/dirty-cow-android-malware.jpg>)\n\nOnce downloaded and installed, the ZNIU malware-carrying app communicates with its command-and-control (C&C) server to check for code updates, while simultaneously the Dirty Cow exploit provides local privilege escalation to gain root access on the device, bypass system restrictions and _\"plant a backdoor for potential remote control attacks in the future.\"_ \n \nThe malware also harvests the carrier information of the user and attempts to send payments via premium SMS messages that were directed to a dummy company in China. \n \nOnce the SMS transaction is over, the malware also deletes the messages from the device in order to erase evidence of any compromise. \n \nThe researchers found the malware has already infected more than 5,000 Android users across 40 countries in recent weeks, with the majority of victims found in China and India, while other resides in the United States, Japan, Canada, Germany and Indonesia. \n \nGoogle has released [an update for Android](<https://source.android.com/security/bulletin/2016-12-01>) that, among other fixes, officially fixes the Dirty COW vulnerability. The tech giant also confirmed that its **[Play Protect](<https://thehackernews.com/2017/05/google-play-protect-android.html>)** now protects Android users against this malware. \n \nThe easiest way to prevent yourself from being targeted by such clever malware is to avoid downloading apps from third-party sources and always stick to the official Google Play Store.\n", "modified": "2017-09-26T13:57:30", "published": "2017-09-26T02:52:00", "id": "THN:1F1264BE105BBA74057A5E702B33D71F", "href": "https://thehackernews.com/2017/09/dirty-cow-android-malware.html", "type": "thn", "title": "First Android Malware Found Exploiting Dirty COW Linux Flaw to Gain Root Privileges", "cvss": {"score": 7.2, "vector": "AV:LOCAL/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}], "securityvulns": [{"lastseen": "2018-08-31T11:10:59", "bulletinFamily": "software", "cvelist": ["CVE-2015-3636", "CVE-2015-4167", "CVE-2015-1805"], "description": "\r\n\r\n-----BEGIN PGP SIGNED MESSAGE-----\r\nHash: SHA512\r\n\r\n- -------------------------------------------------------------------------\r\nDebian Security Advisory DSA-3290-1 security@debian.org\r\nhttps://www.debian.org/security/ Ben Hutchings\r\nJune 18, 2015 https://www.debian.org/security/faq\r\n- -------------------------------------------------------------------------\r\n\r\nPackage : linux\r\nCVE ID : CVE-2015-1805 CVE-2015-3636 CVE-2015-4167\r\n\r\nSeveral vulnerabilities have been discovered in the Linux kernel that\r\nmay lead to a privilege escalation, denial of service, information leaks\r\nor data corruption.\r\n\r\nCVE-2015-1805\r\n\r\n Red Hat discovered that the pipe iovec read and write\r\n implementations may iterate over the iovec twice but will modify the\r\n iovec such that the second iteration accesses the wrong memory.
