Summary

Red Hat Security Advisory: kernel-rt security, bug fix, and enhancement update

Notes

Topic

Updated kernel-rt packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Details

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel's file system implementation handled rename operations in which the source was inside and the destination was outside of a bind mount. A privileged user inside a container could use this flaw to escape the bind mount and, potentially, escalate their privileges on the system. (CVE-2015-2925, Important) * A race condition flaw was found in the way the Linux kernel's IPC subsystem initialized certain fields in an IPC object structure that were later used for permission checking before inserting the object into a globally visible list. A local, unprivileged user could potentially use this flaw to elevate their privileges on the system. (CVE-2015-7613, Important) * It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks. An attacker able to continuously spawn new processes within a single memory-constrained cgroup during an OOM event could use this flaw to lock up the system. (CVE-2014-8171, Moderate) * A race condition flaw was found between the chown and execve system calls. When changing the owner of a setuid user binary to root, the race condition could momentarily make the binary setuid root. A local, unprivileged user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-3339, Moderate) * A flaw was discovered in the way the Linux kernel's TTY subsystem handled the tty shutdown phase. A local, unprivileged user could use this flaw to cause a denial of service on the system by holding a reference to the ldisc lock during tty shutdown, causing a deadlock. (CVE-2015-4170, Moderate) * A NULL pointer dereference flaw was found in the SCTP implementation. A local user could use this flaw to cause a denial of service on the system by triggering a kernel panic when creating multiple sockets in parallel while the system did not have the SCTP module loaded. (CVE-2015-5283, Moderate) * A flaw was found in the way the Linux kernel's Crypto subsystem handled automatic loading of kernel modules. A local user could use this flaw to load any installed kernel module, and thus increase the attack surface of the running kernel. (CVE-2013-7421, CVE-2014-9644, Low) * An information leak flaw was found in the way the Linux kernel changed certain segment registers and thread-local storage (TLS) during a context switch. A local, unprivileged user could use this flaw to leak the user space TLS base address of an arbitrary process. (CVE-2014-9419, Low) * A flaw was found in the way the Linux kernel handled the securelevel functionality after performing a kexec operation. A local attacker could use this flaw to bypass the security mechanism of the securelevel/secureboot combination. (CVE-2015-7837, Low) Red Hat would like to thank Linn Crosetto of HP for reporting the CVE-2015-7837 issue. The CVE-2015-5283 issue was discovered by Ji Jianwen from Red Hat engineering. The kernel-rt packages have been upgraded to version 3.10.0-326.rt56.204, which provides a number of bug fixes and enhancements. (BZ#1201915, BZ#1211724) This update also fixes several bugs and adds multiple enhancements. Refer to the following Red Hat Knowledgebase article for information on the most significant of these changes: https://access.redhat.com/articles/2055783 All kernel-rt users are advised to upgrade to these updated packages, which correct these issues and add these enhancements. The system must be rebooted for this update to take effect.

Vulnerability from cvelistv5

Severity

Summary

The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel through 3.18.1 does not ensure that Thread Local Storage (TLS) descriptors are loaded before proceeding with other steps, which makes it easier for local users to bypass the ASLR protection mechanism via a crafted application that reads a TLS base address.

Severity

Summary

The prepend_path function in fs/dcache.c in the Linux kernel before 4.2.4 does not properly handle rename actions inside a bind mount, which allows local users to bypass an intended container protection mechanism by renaming a directory, related to a "double-chroot attack."

Severity

Summary

The sctp_init function in net/sctp/protocol.c in the Linux kernel before 4.2.3 has an incorrect sequence of protocol-initialization steps, which allows local users to cause a denial of service (panic or memory corruption) by creating SCTP sockets before all of the steps have finished.
