squid3 - denial of service

Squid3, a fully featured Web proxy cache, is prone to a denial of
service attack due to memory consumption caused by memory leaks in
cachemgr.cgi:

• CVE-2012-5643
  squid’s cachemgr.cgi was vulnerable to excessive resource use.
  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.
