Ubuntu Security Announcement USN-1884-1 highlights severe vulnerabilities in the Linux kernel impacting ARMv7 devices. Discover further details.
Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

- linux-ti-omap4: Linux kernel for OMAP4

Details:

Kees Cook discovered a flaw in the Linux kernel's iSCSI subsystem. A remote

unauthenticated attacker could exploit this flaw to cause a denial of

service (system crash) or potentially gain administrative privileges.

(CVE-2013-2850)

An information leak was discovered in the Linux kernel's crypto API. A

local user could exploit this flaw to examine potentially sensitive

information from the kernel's stack memory. (CVE-2013-3076)

An information leak was discovered in the Linux kernel's rcvmsg path for

ATM (Asynchronous Transfer Mode). A local user could exploit this flaw to

examine potentially sensitive information from the kernel's stack memory.

(CVE-2013-3222)

An information leak was discovered in the Linux kernel's recvmsg path for

ax25 address family. A local user could exploit this flaw to examine

potentially sensitive information...

Update Instructions

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

Ubuntu 13.04:
  linux-image-3.5.0-226-omap4     3.5.0-226.39

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. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
