Ubuntu 6.06 LTS / 8.04 LTS / 9.10 : exim4 vulnerability (USN-1032-1)

high Nessus Plugin ID 51136

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
