New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 3.4
SynopsisThe remote Debian host is missing a security-related update.
DescriptionSeveral 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.
SolutionUpgrade the nss packages.
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.
