Debian DSA-474-1 : squid - ACL bypass

high Nessus Plugin ID 15311

Synopsis

The remote Debian host is missing a security-related update.

Description

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).

Solution

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

We recommend that you update your squid package.
