Ubuntu Security Notice USN-3097-2:
13th October, 2016, linux-ti-omap4 vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 12.04 LTS
Summary: Several security issues were fixed in the kernel.
Software description: linux-ti-omap4 - Linux kernel for OMAP4
Details
Marco Grassi discovered a use-after-free condition could occur in the TCP retransmit queue handling code in the Linux Kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-6828)
Pengfei Wang discovered a race condition in the audit subsystem in the Linux kernel. A local attacker could use this to corrupt audit logs or disrupt system-call auditing. (CVE-2016-6136)
Pengfei Wang discovered a race condition in the Adaptec AAC RAID controller driver in the Linux kernel when handling ioctl()s. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-6480). The problem can be corrected by updating your system to the following package version:
linux-image-3.2.0-1489-omap43.2.0-1489.116
To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
