Description Vincent Danen 2009-07-27 16:22:42 UTC

The Squid project released squid 3.0.STABLE17 and 3.1.0.12 today [1], correcting the following issues (from their advisory):

Due to incorrect buffer limits and related bound checks Squid
is vulnerable to a denial of service attack when processing
specially crafted requests or responses.

Due to incorrect data validation Squid is vulnerable to a denial
of service attack when processing specially crafted responses.

These problems allow any trusted client or external server to
perform a denial of service attack on the Squid service.

Comment 1 Vincent Danen 2009-07-27 16:22:56 UTC

Created squid tracking bugs for this issue

Affects: Fdevel [bug #514014]

Comment 2 Vincent Danen 2009-07-27 16:24:57 UTC

Note: these issues only affect squid 3.x, so only Fedora is affected by this.  Red Hat Enterprise Linux 5 and earlier provide squid 2.x which is not affected by these issues.

Common Vulnerabilities and Exposures assigned an identifier CVE-2009-2621 to
the following vulnerability:

Name: CVE-2009-2621

Squid 3.0 through 3.0.STABLE16 and 3.1 through 3.1.0.11 does not
properly enforce "buffer limits and related bound checks," which
allows remote attackers to cause a denial of service via (1) an
incomplete request or (2) a request with a large header size, related
to (a) HttpMsg.cc and (b) client_side.cc.
