- Date Reported:
- 17 Aug 2015
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2015-2721, CVE-2015-2730.
- More information:
Several vulnerabilities have been discovered in nss, the Mozilla Network Security Service library. The Common Vulnerabilities and Exposures project identifies the following problems:
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.
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.
