Elm 'Expires' Header Overflow

High

Synopsis

The remote host is vulnerable to a buffer overflow.

Description

The remote host is running Elm, an email client. This version of Elm is vulnerable to a buffer overflow via the 'Expires' header parameter. An attacker exploiting this flaw would send a specially formed email with a very long 'Expires' value. Successful exploitation would result in arbitrary code being executed.

Solution

Upgrade or patch according to vendor recommendations.
