Description Josh Bressers 2005-02-16 15:58:56 UTC

Squid 2.5.STABLE8 and earlier allows remote attackers to cause a denial of
service (crash) via certain DNS responses regarding (1) Fully Qualified Domain
Names (FQDN) in fqdncache.c or (2) IP addresses in ipcache.c, which trigger an
assertion failure.
