Subject: Security ERRATA Moderate: kernel on SL6.x i386/x86_64
Newsgroups: gmane.linux.scientific.errata
Date: Wednesday 7th November 2012 16:19:41 UTC (over 4 years ago)
Synopsis:          Moderate: kernel security and bug fix update
Issue Date:        2012-11-06
CVE Numbers:       CVE-2012-1568
                    CVE-2012-2133
                    CVE-2012-3400
                    CVE-2012-3511

This update fixes the following security issues:

* A use-after-free flaw was found in the Linux kernel's memory management
subsystem in the way quota handling for huge pages was performed. A local,
unprivileged user could use this flaw to cause a denial of service or,
potentially, escalate their privileges. (CVE-2012-2133, Moderate)

* A use-after-free flaw was found in the madvise() system call
implementation in the Linux kernel. A local, unprivileged user could use
this flaw to cause a denial of service or, potentially, escalate their
privileges. (CVE-2012-3511, Moderate)

* It was found that when running a 32-bit binary that uses a large number
of shared libraries, one of the libraries would always be loaded at a
predictable address in memory. An attacker could use this flaw to bypass
the Address Space Layout Randomization (ASLR) security feature.
(CVE-2012-1568, Low)

* Buffer overflow flaws were found in the udf_load_logicalvol() function
in the Universal Disk Format (UDF) file system implementation in the Linux
kernel. An attacker with physical access to a system could use these flaws
to cause a denial of service or escalate their privileges. (CVE-2012-3400,
Low)

This update also fixes several bugs.

The system must be rebooted for this update to take effect.
