Mandriva Linux Security Advisory MDVSA-2011:193
http://www.mandriva.com/security/
_______________________________________________________________________

Package : squid
Date : December 27, 2011
Affected: 2011.
_______________________________________________________________________

Problem Description:

A vulnerability has been discovered and corrected in squid:

The idnsGrokReply function in Squid before 3.1.16 does not properly
free memory, which allows remote attackers to cause a denial of
service (daemon abort) via a DNS reply containing a CNAME record
that references another CNAME record that contains an empty A record
(CVE-2011-4096).

The updated packages have been patched to correct this issue.
