DLA-315-1 nss -- LTS security update
- Date Reported:
- 27 Sep 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 oldoldstable distribution (squeeze), these problems have been fixed in version 3.12.8-1+squeeze12.
We recommend that you upgrade your nss packages.
