A flaw in the way mutt processed certain APOP authentication requests was discovered. By sending certain responses when mutt attempted to authenticate again an APOP server, a remote attacker could possibly obtain certain portions of the user's authentication credentials (CVE-2007-1558). A flaw in how mutt handled certain characters in gecos fields could lead to a buffer overflow. A local user able to give themselves a carefully crafted Real Name could potentially execute arbitrary code if a victim used mutt to expand the attacker's alias (CVE-2007-2683). Updated packages have been patched to address these issues.
mutt on Mandriva Linux 2007.0, Mandriva Linux 2007.0/X86_64, Mandriva Linux 2007.1, Mandriva Linux 2007.1/X86_64
