Description

A vulnerability in squid was discovered that could be remotely exploited by using a special ftp:// URL (CVE-2007-0247).

Another Denial of Service vulnerability was discovered in squid 2.6 that allows remote attackers to crash the server by causing an external_acl_queue overload (CVE-2007-0248).

Additionally, a bug in squid 2.6 for max_user_ip handling in ntlm_auth has been corrected.

The updated packages have been patched to correct this problem.
