A remote attacker could exploit this flaw to perform a denial of service attack on the server and other hosted services. CVE-2013-0189 The original patch for CVE-2012-5643 was incomplete. A remote attacker still could exploit this flaw to perform a denial of service attack. For the stable distribution (squeeze), these problems have been fixed in version 3.1.6-1.2+squeeze3. For the testing distribution (wheezy), these problems have been fixed in version 3.1.20-2.1. For the unstable distribution (sid), these problems have been fixed in version 3.1.20-2.1. We recommend that you upgrade your squid3 packages.
