Mandriva Linux Security Advisory : squid (MDVSA-2011:193)

Medium Nessus Plugin ID 61941


The remote Mandriva Linux host is missing one or more security updates.


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.


Update the affected squid and / or squid-cachemgr packages.
