Ubuntu Security Notice USN-1826-1
May 16, 2013
linux vulnerability
==========================
==========================
========================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.10
Summary:
The system could be made to run programs as an administrator.
Software Description:
- linux: Linux kernel
Details:
An flaw was discovered in the Linux kernel's perf_events interface. A loc=
al
user could exploit this flaw to escalate privileges on the system.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.10:
linux-image-3.5.0-30-generic 3.5.0-30.51
linux-image-3.5.0-30-highbank 3.5.0-30.51
linux-image-3.5.0-30-omap 3.5.0-30.51
linux-image-3.5.0-30-powerpc-smp 3.5.0-30.51
linux-image-3.5.0-30-powerpc64-smp 3.5.0-30.51
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 automaticall=
y
perform this as well.
