Summary

The remote host is missing updates announced in advisory GLSA 200403-11.

Insight

Insight

Squid versions 2.0 through to 2.5.STABLE4 could allow a remote attacker to bypass Access Control Lists by sending a specially-crafted URL request containing '%00': in such circumstances the url_regex ACL may not properly detect the malicious URL, allowing the attacker to effectively bypass the ACL.

Solution

Solution

Squid can be updated as follows: # emerge sync # emerge -pv '>=www-proxy/squid-2.5.5' # emerge '>=www-proxy/squid-2.5.5' http://www.securityspace.com/smysecure/catid.html?in=GLSA%20200403-11 http://bugs.gentoo.org/show_bug.cgi?id=45273 http://www.squid-cache.org/Advisories/SQUID-2004_1.txt
