Package : nss
CVE ID : CVE-2015-2721 CVE-2015-2730
Several vulnerabilities have been discovered in nss, the Mozilla Network Security Service library. The Common Vulnerabilities and Exposures project identifies the following problems:
CVE-2015-2721
Karthikeyan Bhargavan discovered that NSS incorrectly handles state
transitions for the TLS state machine. A man-in-the-middle attacker
could exploit this flaw to skip the ServerKeyExchange message and
remove the forward-secrecy property.
CVE-2015-2730
Watson Ladd discovered that NSS does not properly perform Elliptical
Curve Cryptography (ECC) multiplication, allowing a remote attacker
to potentially spoof ECDSA signatures.
For the oldstable distribution (wheezy), these problems have been fixed
in version 2:3.14.5-1+deb7u5.
For the stable distribution (jessie), these problems have been fixed in
version 2:3.17.2-1.1+deb8u1.
For the testing distribution (stretch), these problems have been fixed
in version 2:3.19.1-1.
For the unstable distribution (sid), these problems have been fixed in
version 2:3.19.1-1.
We recommend that you upgrade your nss packages.
