Vulnerability Details : CVE-2013-1623
The TLS and DTLS implementations in wolfSSL CyaSSL before 2.5.0 do 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.
