All supported architectures
Two vulnerabilities have been found in Squid which make it susceptible to
Denial of Service attacks.
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:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-proxy/squid-2.6.7"
