Ubuntu Security Notice USN-1845-1
May 30, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
The system could be made to crash or run programs as an administrator if
it received specially crafted network traffic.
- linux-lts-quantal: Linux hardware enablement kernel from Quantal
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.
The problem can be corrected by updating your system to the following
Ubuntu 12.04 LTS:
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.
