Version Information

Release Date June 28, 2006
Latest Revision June 28, 2006: 01
Impact normal

Package Vulnerable versions Unaffected versions Architecture(s)
mail-client/mutt < 1.5.11-r2 >= 1.5.11-r2 All supported architectures

Related bugreports: #138125


Mutt contains a buffer overflow that could result in arbitrary code execution.

2.  Impact Information


Mutt is a small but very powerful text-based mail client.


TAKAHASHI Tamotsu has discovered that Mutt contains a boundary error in the "browse_get_namespace()" function in browse.c, which can be triggered when receiving an overly long namespace from an IMAP server.


A malicious IMAP server can send an overly long namespace to Mutt in order to crash the application, and possibly execute arbitrary code with the permissions of the user running Mutt.

3.  Resolution Information


There is no known workaround at this time.


All Mutt users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mutt-1.5.11-r2"
