GLSA-200606-27 : Mutt: Buffer overflow
High Nessus Plugin ID 21773
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200606-27 (Mutt: Buffer overflow)
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.
There is no known workaround at this time.
SolutionAll Mutt users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=mail-client/mutt-1.5.11-r2'
