Ubuntu Security Notice 3126-2 - Ondrej Kozina discovered that the keyring interface in the Linux kernel contained a buffer overflow when displaying timeout events via the /proc/keys interface. A local attacker could use this to cause a denial of service. Dmitry Vyukov discovered a use-after-free vulnerability during error processing in the recvmmsg implementation in the Linux kernel. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

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:

Ondrej Kozina discovered that the keyring interface in the Linux kernel
contained a buffer overflow when displaying timeout events via the
/proc/keys interface. A local attacker could use this to cause a denial of
service (system crash). (CVE-2016-7042)

Dmitry Vyukov discovered a use-after-free vulnerability during error
processing in the recvmmsg(2) implementation in the Linux kernel. A remote
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2016-7117)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-1493-omap4 3.2.0-1493.120
linux-image-omap4 3.2.0.1493.88

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.
