Technical Description

Mandriva has released updated packages to address a vulnerability identified in Fetchmail. This flaw is due to a null pointer dereference error when processing messages without headers, which could be exploited by attackers to crash a vulnerable application (configured for multidrop mode) via a malicious upstream mail server. For additional information, see : VUPEN/ADV-2005-2996
