2.  Impact Information


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


A heap-based buffer overflow has been discovered in the mutt_copy_hdr function.


A remote attacker could send a specially crafted message, possibly resulting in execution of arbitrary code with the privileges of the user running Mutt or a Denial of Service condition.

There is no known workaround at this time.


All Mutt users should upgrade to the latest version:
