While processing SACK segments, the Linux kernel's socket buffer (SKB) data structure becomes fragmented. Each fragment is about TCP maximum segment size (MSS) bytes. To efficiently process SACK blocks, the Linux kernel merges multiple fragmented SKBs into one, potentially overflowing the variable holding the number of segments. A remote attacker could use this flaw to crash the Linux kernel by sending a crafted sequence of SACK segments on a TCP connection with small value of TCP MSS, resulting in a denial of service (DoS). (CVE-2019-11477)\n\n - Kernel: tcp: excessive resource consumption while processing SACK blocks allows remote denial of service (CVE-2019-11478)\n\n - Kernel: tcp: excessive resource consumption for TCP connections with low MSS allows remote denial of service (CVE-2019-11479)\n\n - The Linux kernel is vulnerable to an out-of-bounds read in ext4/balloc.c:ext4_valid_block_bitmap() function. An attacker could trick a legitimate user or a privileged attacker could exploit this by mounting a crafted ext4 image to cause a crash.(CVE-2018-1093)\n\n - The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel before 5.0.8 has multiple race conditions.(CVE-2019-11486)\n\n - A flaw was found in the Linux kernel where the coredump implementation does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs. This allows local users to obtain sensitive information, cause a denial of service (DoS), or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls.(CVE-2019-11599)\n\n - A race condition in perf_event_open() allows local attackers to leak sensitive data from setuid programs.\n As no relevant locks (in particular the cred_guard_mutex) are held during the ptrace_may_access() call, it is possible for the specified target task to perform an execve() syscall with setuid execution before perf_event_alloc() actually attaches to it, allowing an attacker to bypass the ptrace_may_access() check and the perf_event_exit_task(current) call that is performed in install_exec_creds() during privileged execve() calls.(CVE-2019-3901)\n\n - In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before register_netdevice.

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-alt packages provide the Linux kernel version 4.x.\n\nSecurity Fix(es) :\n\n* An integer overflow flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment (SACK) segments.

While processing SACK segments, the Linux kernel's socket buffer (SKB) data structure becomes fragmented. Each fragment is about TCP maximum segment size (MSS) bytes.

(CVE-2019-11477)\n\n - An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment (SACK) segments. While processing SACK segments, the Linux kernel's socket buffer (SKB) data structure becomes fragmented, which leads to increased resource utilization to traverse and process these fragments as further SACK segments are received on the same TCP connection. A remote attacker could use this flaw to cause a denial of service (DoS) by sending a crafted sequence of SACK segments on a TCP connection. (CVE-2019-11478)\n\n - An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP segments.

(CVE-2011-1079)\n\n - An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout()\n and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. (CVE-2018-20836)\n\n - An issue was discovered in the Linux kernel before 5.0.7. A NULL pointer dereference can occur when\n megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c.\n This causes a Denial of Service, related to a use-after-free. (CVE-2019-11810)\n\n - An issue was discovered in rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel before 5.0.8.

This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127,\n 4.19.52, 5.1.11, and is fixed in commit 3b4929f65b0d8249f19a50245cd88ed1a2f78cff. (CVE-2019-11477)\n\n - Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a\n remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote\n attacker could use this to cause a denial of service. This has been fixed in stable kernel releases\n 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commits\n 967c05aee439e6e5d7d805e195b3a20ef5c433d6 and 5f3e2bf008c2221478101ee72f5cb4654b9fc363.

for kernel-rt is now available for Red Hat Enterprise Linux 8.\n\nRed Hat Product Security has rated this update as having a security impact of Important. 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-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.\n\nSecurity Fix(es) :\n\n* An integer overflow flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment (SACK) segments.

Uncacheable memory on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2019-11091)\n\n - An integer overflow flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment (SACK) segments. While processing SACK segments, the Linux kernel's socket buffer (SKB) data structure becomes fragmented. Each fragment is about TCP maximum segment size (MSS) bytes. To efficiently process SACK blocks, the Linux kernel merges multiple fragmented SKBs into one, potentially overflowing the variable holding the number of segments. A remote attacker could use this flaw to crash the Linux kernel by sending a crafted sequence of SACK segments on a TCP connection with small value of TCP MSS, resulting in a denial of service (DoS). (CVE-2019-11477)\n\n - An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment (SACK) segments. While processing SACK segments, the Linux kernel's socket buffer (SKB) data structure becomes fragmented, which leads to increased resource utilization to traverse and process these fragments as further SACK segments are received on the same TCP connection. A remote attacker could use this flaw to cause a denial of service (DoS) by sending a crafted sequence of SACK segments on a TCP connection. (CVE-2019-11478)\n\n - An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP segments. If the Maximum Segment Size (MSS) of a TCP connection was set to low values, such as 48 bytes, it can leave as little as 8 bytes for the user data, which significantly increases the Linux kernel's resource (CPU, Memory, and Bandwidth) utilization.

vulnerabilities :\n\n - A vulnerability was found in polkit. When authentication is performed by a non-root user to perform an administrative task, the authentication is temporarily cached in such a way that a local attacker could impersonate the authorized process, thus gaining access to elevated privileges.(CVE-2019-6133)\n\n - A race condition in perf_event_open() allows local attackers to leak sensitive data from setuid programs.\n As no relevant locks (in particular the cred_guard_mutex) are held during the ptrace_may_access() call, it is possible for the specified target task to perform an execve() syscall with setuid execution before perf_event_alloc() actually attaches to it, allowing an attacker to bypass the ptrace_may_access() check and the perf_event_exit_task(current) call that is performed in install_exec_creds() during privileged execve() calls.(CVE-2019-3901)\n\n - A race condition was found between between mmget_not_zero()/get_task_mm() when core dumping tasks.\n A local attacker is able to exploit race condition where locking of semaphore would allow an attacker to leak kernel memory to userspace.(CVE-2019-3892)\n\n - A flaw was found in the Linux kernel where the coredump implementation does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs. This allows local users to obtain sensitive information, cause a denial of service (DoS), or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls.(CVE-2019-11599)\n\n - An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free.(CVE-2018-20836)\n\n - A flaw was found in the Linux kernel, prior to version 5.0.7, in drivers/scsi/megaraid/megaraid_sas_base.c, where a NULL pointer dereference can occur when megasas_create_frame_pool() fails in megasas_alloc_cmds(). An attacker can crash the system if they were able to load the megaraid_sas kernel module and groom memory beforehand, leading to a denial of service (DoS), related to a use-after-free.(CVE-2019-11810)\n\n - A flaw was found in the Linux kernel's implementation of RDS over TCP. A system that has the rds_tcp kernel module loaded (either through autoload via local process running listen(), or manual loading) could possibly cause a use after free (UAF) in which an attacker who is able to manipulate socket state while a network namespace is being torn down. This can lead to possible memory corruption and privilege escalation.(CVE-2019-11815)\n\n - Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer.(CVE-2018-12126)\n\n - A flaw was found in the implementation of the 'fill buffer', a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer.(CVE-2018-12130)\n\n - Microprocessors use a aEUR~load portaEURtm subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPUaEURtms pipelines. Stale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side-channel.(CVE-2018-12127)\n\n - Uncacheable memory on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.(CVE-2019-11091)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

A\n remote attacker could use this flaw to cause a denial\n of service (DoS) by sending a crafted sequence of SACK\n segments on a TCP connection.\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the Virtuozzo security advisory.\nTenable has attempted to automatically clean and format it as much as\npossible without introducing additional issues.\");\n script_set_attribute(attribute:\"see_also\", value:\"https://virtuozzosupport.force.com/s/article/VZA-2019-050\");\n script_set_attribute(attribute:\"see_also\", value:\"https://readykernel.com/patch/1572/\");\n script_set_attribute(attribute:\"see_also\", value:\"https://readykernel.com/patch/1574/\");\n script_set_attribute(attribute:\"see_also\", value:\"https://readykernel.com/patch/1576/\");\n script_set_attribute(attribute:\"see_also\", value:\"https://readykernel.com/patch/1578/\");\n script_set_attribute(attribute:\"see_also\", value:\"https://readykernel.com/patch/1579/\");\n script_set_attribute(attribute:\"see_also\", value:\"https://readykernel.com/patch/1582/\");\n script_set_attribute(attribute:\"see_also\", value:\"https://readykernel.com/patch/1583/\");\n script_set_attribute(attribute:\"see_also\", value:\"https://readykernel.com/patch/1584/\");\n script_set_attribute(attribute:\"see_also\", value:\"https://readykernel.com/patch/1587/\");\n script_set_attribute(attribute:\"see_also\", value:\"https://readykernel.com/patch/1590/\");\n script_set_attribute(attribute:\"solution\", value:\n\"Update the readykernel patch.\");\n script_set_cvss_base_vector(\"CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:C\");\n script_set_cvss_temporal_vector(\"CVSS2#E:U/RL:OF/RC:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H\");\n script_set_cvss3_temporal_vector(\"CVSS:3.0/E:U/RL:O/RC:C\");\n\n script_set_attribute(attribute:\"exploitability_ease\", value:\"No known exploits are available\");\n\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2019/06/20\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2020/02/04\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:virtuozzo:virtuozzo:readykernel\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:virtuozzo:virtuozzo:7\");\n script_set_attribute(attribute:\"generated_plugin\", value:\"current\");\n script_end_attributes();\n\n script_category(ACT_GATHER_INFO);\n script_family(english:\"Virtuozzo Local Security Checks\");\n\n script_copyright(english:\"This script is Copyright (C) 2020-2022 and is owned by Tenable, Inc. or an Affiliate thereof.\");\n\n script_dependencies(\"ssh_get_info.nasl\");\n script_require_keys(\"Host/local_checks_enabled\", \"Host/Virtuozzo/release\", \"Host/Virtuozzo/rpm-list\", \"Host/readykernel-info\");\n\n exit(0);\n}\n\ninclude(\"global_settings.inc\");\ninclude(\"readykernel.inc\");\n\nif (!get_kb_item(\"Host/local_checks_enabled\")) audit(AUDIT_LOCAL_CHECKS_NOT_ENABLED);\n\nrelease = get_kb_item(\"Host/Virtuozzo/release\");\nif (isnull(release) || \"Virtuozzo\" >!< release) audit(AUDIT_OS_NOT, \"Virtuozzo\");\nos_ver = pregmatch(pattern: \"Virtuozzo Linux release ([0-9]+\\.[0-9])(\\D|$)\", string:release);\nif (isnull(os_ver)) audit(AUDIT_UNKNOWN_APP_VER, \"Virtuozzo\");\nos_ver = os_ver[1];\nif (!
