The remote host is missing an update to squid announced via advisory DSA 809-2. 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 the oldstable distribution (woody) this problem has been fixed in version 2.4.6-2woody10.

For the stable distribution (sarge) this problem has been fixed in version 2.5.9-10sarge1. For the unstable distribution (sid) this problem has been fixed in version 2.5.10-5. We recommend that you upgrade your squid package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20809-2
