Squid: Multiple Denial of Service vulnerabilities Two vulnerabilities have been found in Squid which make it susceptible to Denial of Service attacks. squid 2007-01-25 2007-01-25 162364 remote 2.6.7 2.6.7

Squid is a multi-protocol proxy server.

Squid fails to correctly handle ftp:// URI's. There is also an error in the external_acl queue which can cause an infinite looping condition.

An attacker could attempt to retrieve a specially crafted URI via a Squid server causing the service to crash. If an attacker could generate a sufficiently high load on the Squid services, they could cause a Denial of Service by forcing Squid into an infinite loop.

There is no known workaround at this time.

All Squid users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-proxy/squid-2.6.7"
