Ubuntu Security Notice USN-1741-1
February 22, 2013
linux vulnerability
============================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
The system could be made to run programs as an administrator.
Software Description:
- linux: Linux kernel
Details:
Suleiman Souhlal, Salman Qazi, Aaron Durbin and Michael Davidson discovered
a race condition in the Linux kernel's ptrace syscall. An unprivileged
local attacker could exploit this flaw to run programs as an administrator.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 LTS:
linux-image-3.2.0-38-generic 3.2.0-38.61
linux-image-3.2.0-38-generic-pae 3.2.0-38.61
linux-image-3.2.0-38-highbank 3.2.0-38.61
linux-image-3.2.0-38-omap 3.2.0-38.61
linux-image-3.2.0-38-powerpc-smp 3.2.0-38.61
linux-image-3.2.0-38-powerpc64-smp 3.2.0-38.61
linux-image-3.2.0-38-virtual 3.2.0-38.61
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.
