Detailsinfo

A vulnerability classified as problematic was found in Squid Proxy up to 3.1.0.11 (Firewall Software). Affected by this vulnerability is some unknown functionality of the file HttpMsg.cc. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect availability. The summary by CVE is:

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.

The weakness was disclosed 07/28/2009 by Rob Middleton with Codenomicon (Website). The advisory is shared at squid-cache.org. This vulnerability is known as CVE-2009-2621 since 07/28/2009. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 40399 (Mandriva Linux Security Advisory : squid (MDVSA-2009:161-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 116562 (Fedora Update for Squid (FEDORA-2009-8324, FEDORA-2009-8327)).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 8677.

The vulnerability is also documented in the databases at Tenable (40399), SecurityFocus (BID 35812†), Secunia (SA36007†), SecurityTracker (ID 1022607†) and Vulnerability Center (SBV-22992†).
