Debian DSA-809-2 : squid - several vulnerabilities

medium Nessus Plugin ID 19684


The remote Debian host is missing a security-related update.


Certain aborted requests that trigger an assertion in squid, the popular WWW proxy cache, may allow remote attackers to cause a denial of service. This update also fixes a regression caused by DSA 751.
For completeness below is the original advisory text :

Several vulnerabilities have been discovered in Squid, the popular WWW proxy cache. The Common Vulnerabilities and Exposures project identifies the following problems :

- CAN-2005-2794 Certain aborted requests that trigger an assert may allow remote attackers to cause a denial of service.

- CAN-2005-2796

Specially crafted requests can cause a denial of service.


Upgrade the squid package.

For the oldstable distribution (woody) this problem has been fixed in version 2.4.6-2woody10.

For the stable distribution (sarge) these problems have been fixed in version 2.5.9-10sarge1.
