Security bypass vulnerability in the Mozilla Network Security Services (NSS) in Mozilla products by blocking a ServerKeyExchange message - MFSA-2015-71 (Mac OS X)

ID: oval:org.secpod.oval:def:25577Date: (C)2015-08-06   (M)2018-09-17
Class: PATCHFamily: macos




The host is missing a critical security update according to Mozilla advisory, MFSA-2015-71. The update is required to fix a security bypass vulnerability. A flaw is present in the applications, which do not properly determine state transitions for the TLS state machine. Successful exploitation could allow man-in-the-middle attackers to defeat cryptographic protection mechanisms by blocking messages, as demonstrated by removing a forward-secrecy property by blocking a ServerKeyExchange message, aka a "SMACK SKIP-TLS" issue.
