nss - several vulnerabilities

Several vulnerabilities have been discovered in the Network Security
Service libraries. The Common Vulnerabilities and Exposures project
identifies the following problems:

• CVE-2009-2404
  Moxie Marlinspike discovered that a buffer overflow in the regular
  expression parser could lead to the execution of arbitrary code.
• CVE-2009-2408
  Dan Kaminsky discovered that NULL characters in certificate
  names could lead to man-in-the-middle attacks by tricking the user
  into accepting a rogue certificate.
• CVE-2009-2409
  Certificates with MD2 hash signatures are no longer accepted
  since they’re no longer considered cryptograhically secure.

The old stable distribution (etch) doesn’t contain nss.

For the stable distribution (lenny), these problems have been fixed in
version 3.12.3.1-0lenny1.

For the unstable distribution (sid), these problems have been fixed in
version 3.12.3.1-1.

We recommend that you upgrade your nss packages.
