Fedora Core 5: 2007-540 Critical: Mutt APOP & Buffer Overflow Threat

Mutt is a text-mode mail user agent. Mutt supports color, threading,

arbitrary key remapping, and a lot of customization.

You should install mutt if you have used it in the past and you prefer

it, or if you are new to mail programs and have not decided which one

you are going to use.

This update fixes two security issues:

The APOP protocol allows remote attackers to guess the first

3 characters of a password via man-in-the-middle (MITM)

attacks that use crafted message IDs and MD5 collisions.

(CVE-2007-1558)

Buffer overflow in Mutt 1.4.2 might allow local users to

execute arbitrary code via "&" characters in the GECOS

field, which triggers the overflow during alias expansion.

(CVE-2007-2683)

- validate msgid in APOP authentication (CVE-2007-1558)

- fix overflow in gecos field handling (CVE-2007-2683)
