USN-3187-2: Linux kernel (OMAP4) vulnerabilities

Releases

• Ubuntu 12.04

Packages

• linux-ti-omap4 - Linux kernel for OMAP4

Details

Andrey Konovalov discovered that the SCTP implementation in the Linux
kernel improperly handled validation of incoming data. A remote attacker
could use this to cause a denial of service (system crash). (CVE-2016-9555)

It was discovered that multiple memory leaks existed in the XFS
implementation in the Linux kernel. A local attacker could use this to
cause a denial of service (memory consumption). (CVE-2016-9685)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.04

• linux-image-omap4 - 3.2.0.1499.94
• linux-image-3.2.0-1499-omap4 - 3.2.0-1499.126

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.
