Mandriva Linux Security Advisory MDVSA-2009:201-1
http://www.mandriva.com/security/
_______________________________________________________________________

Package : fetchmail
Date : December 4, 2009
Affected: 2008.0
_______________________________________________________________________

Problem Description:

A vulnerability has been found and corrected in fetchmail:

socket.c in fetchmail before 6.3.11 does not properly handle a '\0'
(NUL) character in a domain name in the subject's Common Name (CN)
and subjectAlt(ernative)Name fields of an X.509 certificate, which
allows man-in-the-middle attackers to spoof arbitrary SSL servers via
a crafted certificate issued by a legitimate Certification Authority,
a related issue to CVE-2009-2408 (CVE-2009-2666).

This update provides a solution to this vulnerability.

Update:

Packages for 2008.0 are being provided due to extended support for
Corporate products.
