Mandriva Linux Security Advisory 2009-078 – A wrong handling of signed Secure/Multipurpose Internet Mail Extensions (S/MIME) e-mail messages enables attackers to spoof its signatures by modifying the latter copy. Crafted authentication challange packets (NT Lan Manager type 2) sent by a malicious remote mail server enables remote attackers either to cause denial of service and to read information from the process memory of the client. Multiple integer overflows in Base64 encoding functions enables attackers either to cause denial of service and to execute arbitrary code. This update provides fixes for those vulnerabilities. evolution-data-server packages from Mandriva Linux distributions 2008.1 and 2009.0 are not affected by CVE-2009-0587.
