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.
