Description:   Opened: 2005-02-14 07:00 0000 
Description:
A vulnerability has been reported in Squid, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an assertion error when performing FQDN lookups and can be exploited to crash Squid by returning a specially crafted DNS response.

The vulnerability has been reported in Squid-2.5.STABLE5 through 2.5.STABLE8.

NOTE: The risk is reportedly reduced with "log_fqdn off" (default setting).

Solution:
Apply patch for 2.5.STABLE8:
http://www.squid-cache.org/Versi...uid-2.5.STABLE8-dns_assert.patch

Original Advisory:
