-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-3336-1 security@debian.org https://www.debian.org/security/ Salvatore Bonaccorso August 17, 2015 https://www.debian.org/security/faq - ------------------------------------------------------------------------- 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.
