Package : squid
Problem-Type : ACL bypass
Debian-specific: no
CVE Ids : CAN-2004-0189

A vulnerability was discovered in squid, an Internet object cache, whereby access control lists based on URLs could be bypassed (CAN-2004-0189). Two other bugs were also fixed with patches squid-2.4.STABLE7-url_escape.patch (a buffer overrun which does not appear to be exploitable) and squid-2.4.STABLE7-url_port.patch (a potential denial of service).

For the stable distribution (woody) these problems have been fixed in version 2.4.6-2woody2.

For the unstable distribution (sid) these problems have been fixed in version 2.5.5-1.

We recommend that you update your squid package.
