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.

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.

For the unstable distribution (sid) these problems have been fixed in version 2.5.10-5.

We recommend that you upgrade your squid package.");
