High Nessus Plugin ID 129466

Synopsis

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

Description

It was discovered that Exim incorrectly handled certain string operations. A remote attacker could use this issue to cause Exim to crash, resulting in a denial of service, or possibly execute arbitrary code.

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.
