Published Feb 8, 2013
4.3
MEDIUMCVSS 2.0
EPSS 3.72%
Description
The TLS implementation in Mozilla Network Security Services (NSS) does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, a related issue to CVE-2013-0169.
