Several vulnerabilities have been discovered in nss, the Mozilla Network Security Service library:
Runaway memset in certificate parsing on 64-bit computers leading to a crash by attempting to write 4Gb of nulls.
Certificate validation with the verifylog mode did not return validation errors, but instead expected applications to determine the status by looking at the log.
Ticket handling protection mechanisms bypass due to the lack of restriction of public values in Diffie-Hellman key exchanges.
Incorrect IDNA domain name matching for wildcard certificates could allow specially-crafted invalid certificates to be considered as valid.
For the stable distribution (wheezy), these problems have been fixed in version 2:3.14.5-1+deb7u1.
For the testing distribution (jessie), and the unstable distribution (sid), these problems have been fixed in version 2:3.16-1.
We recommend that you upgrade your nss packages.
