USN-1032-1: Exim vulnerability

11 December 2010

A remote attacker could send crafted email to gain root access.




Sergey Kononenko and Eugene Bujak discovered that Exim did not correctly
truncate string expansions. A remote attacker could send specially crafted
email traffic to run arbitrary code as the Exim user, which could also
lead to root privileges.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.10
Ubuntu 8.04
Ubuntu 6.06

In general, a standard system update will make all the necessary changes.
