CVE-2013-1624 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:15.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream bouncycastle package and not the bouncycastle package as distributed by Ubuntu.
The TLS implementation in the Bouncy Castle Java library before 1.48 and C# library before 1.8 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.
