Ubuntu 10.04 LTS / 10.10 / 11.04 : dovecot vulnerability (USN-1143-1)

medium Nessus Plugin ID 55106

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

It was discovered that the message header parser in Dovecot did not properly handle '\0' characters in header names. This could allow a remote attacker to cause a denial of service through a crafted email message by crashing the Dovecot daemon or corrupting mailboxes.

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 dovecot-common package.
