Ubuntu Security Notice USN-1653-1
December 04, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
The system could be made to run programs as an administrator.
- linux-ec2: Linux kernel for EC2
Rodrigo Freire discovered a flaw in the Linux kernel's TCP illinois
congestion control algorithm. A local attacker could use this to cause a
denial of service.
The problem can be corrected by updating your system to the following
Ubuntu 10.04 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.
