USN-1838-1: Linux kernel (OMAP4) vulnerabilities
30 May 2013
Several security issues were fixed in the kernel.
- linux-ti-omap4 - Linux kernel for OMAP4
An flaw was discovered in the Linux kernel's perf_events interface. A local
user could exploit this flaw to escalate privileges on the system.
A buffer overflow vulnerability was discovered in the Broadcom tg3 ethernet
driver for the Linux kernel. A local user could exploit this flaw to cause
a denial of service (crash the system) or potentially escalate privileges
on the system. (CVE-2013-1929)
A flaw was discovered in the Linux kernel's ftrace subsystem interface. A
local user could exploit this flaw to cause a denial of service (system
The problem can be corrected by updating your system to the following package versions:
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.
