Description


A vulnerability has been reported in mutt, which potentially can be exploited by malicious, local users to gain escalated privileges.

A boundary error in the "mutt_gecos_name()" function when processing "&" characters in the GECOS field can be exploited to cause a buffer overflow during alias expansion.

Successful exploitation may allow execution of arbitrary code with another user's privileges, but requires that the malicious user has a specially crafted realname and exists in the target user's alias file.


Solution:
Update to version 1.4.2.3.
