                                        http://security.gentoo.org/

Severity: Normal
Title: Mutt: Buffer overflow
Date: June 28, 2006
Bugs: #138125
ID: 200606-27

Synopsis

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

Background

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

Affected packages

-------------------------------------------------------------------
 Package           /   Vulnerable   /                   Unaffected
-------------------------------------------------------------------

1 mail-client/mutt < 1.5.11-r2 >= 1.5.11-r2

Description

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.

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

All Mutt users should upgrade to the latest version:

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