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.

Comment 3 Vincent Danen 2009-07-28 17:12:11 UTC
Common Vulnerabilities and Exposures assigned an identifier CVE-2009-2621 to
the following vulnerability:

Name: CVE-2009-2621
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?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.

Reference: CONFIRM: http://www.squid-cache.org/Versions/v3/3.1/changesets/b9661.patch

Squid 3.0 through 3.0.STABLE16 and 3.1 through 3.1.0.11 allows remote
attackers to cause a denial of service via malformed requests
including (1) "missing or mismatched protocol identifier," (2) missing
or negative status value," (3) "missing version," or (4) "missing or
invalid status number," related to (a) HttpMsg.cc and (b)
