An attacker could craft ASN.1 data to forge RSA certificates with a valid certification chain to a trusted CA.

For the stable distribution (wheezy), this problem has been fixed in version 2:3.14.5-1+deb7u2.

For the testing distribution (jessie), this problem has been fixed in version 2:3.17.1.

For the unstable distribution (sid), this problem has been fixed in version 2:3.17.1.

We recommend that you upgrade your nss packages.");
