Ubuntu 4.10 / 5.04 / 5.10 : fetchmail vulnerability (USN-233-1)

high Nessus Plugin ID 20777

Synopsis

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

Description

Steve Fosdick discovered a remote Denial of Service vulnerability in fetchmail. When using fetchmail in 'multidrop' mode, a malicious email server could cause a crash by sending an email without any headers.
Since fetchmail is commonly called automatically (with cron, for example), this crash could go unnoticed.

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 fetchmail, fetchmail-ssl and / or fetchmailconf packages.
