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.");
