tomcat6 - several

Two security issues have been found in the Tomcat servlet and JSP engine:

• CVE-2012-3544
  The input filter for chunked transfer encodings could trigger high
  resource consumption through malformed CRLF sequences, resulting in
  denial of service.
• CVE-2013-2067
  The FormAuthenticator module was vulnerable to session fixation.

For the oldstable distribution (squeeze), these problems have been fixed in
version 6.0.35-1+squeeze3. This update also provides fixes for
CVE-2012-2733,
CVE-2012-3546,
CVE-2012-4431,
CVE-2012-4534,
CVE-2012-5885,
CVE-2012-5886 and
CVE-2012-5887,
which were all fixed for stable already.

For the stable distribution (wheezy), these problems have been fixed in
version 6.0.35-6+deb7u1.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your tomcat6 packages.
