Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS

Summary:

An attacker could trick mutt into trusting a rogue server.

Software Description: - mutt: text-based mailreader supporting MIME, GPG, PGP and threading

Details:

It was discovered that mutt incorrectly verified the hostname in an SSL certificate. An attacker could trick mutt into trusting a rogue SMTPS, IMAPS, or POP3S server's certificate, which was signed by a trusted certificate authority, to perform a man-in-the-middle attack.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 11.04:
mutt 1.5.21-2ubuntu3.1
mutt-patched 1.5.21-2ubuntu3.1

Ubuntu 10.10:
mutt 1.5.20-9ubuntu2.1
mutt-patched 1.5.20-9ubuntu2.1

Ubuntu 10.04 LTS:
mutt 1.5.20-7ubuntu1.1
mutt-patched 1.5.20-7ubuntu1.1

After a standard system update you need to restart mutt to make all the necessary changes. Users are encouraged to verify their ~/.mutt_certificates file to ensure only trusted certificates are listed.
