Debian DSA-774-1 : fetchmail - buffer overflow

medium Nessus Plugin ID 19430

Synopsis

The remote Debian host is missing a security-related update.

Description

Edward Shornock discovered a bug in the UIDL handling code of fetchmail, a common POP3, APOP and IMAP mail fetching utility. A malicious POP3 server could exploit this problem and inject arbitrary code that will be executed on the victim host. If fetchmail is running as root, this becomes a root exploit.

Solution

Upgrade the fetchmail package.

The old stable distribution (woody) is not affected by this problem.

For the stable distribution (sarge) this problem has been fixed in version 6.2.5-12sarge1.
