Boris 'pi' Piwinger and Tavis Ormandy reported a heap overflow vulnerability in procmail's formail utility when processing specially crafted email headers. A remote attacker could use this flaw to cause formail to crash, resulting in a denial of service or data loss, or possibly execute arbitrary code.
