CVE-2011-4096

Publication date 17 November 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
