 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.
