Vulnerability Summary for CVE-2013-0169

Overview

The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and other products, do not properly consider timing side-channel attacks on a MAC check requirement 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, aka the "Lucky Thirteen" issue.

Description

Per http://www.openssl.org/news/vulnerabilities.html: Fixed in OpenSSL 1.0.1d (Affected 1.0.1c, 1.0.1b, 1.0.1a, 1.0.1) Fixed in OpenSSL 1.0.0k (Affected 1.0.0j, 1.0.0i, 1.0.0g, 1.0.0f, 1.0.0e, 1.0.0d, 1.0.0c, 1.0.0b, 1.0.0a, 1.0.0) Fixed in OpenSSL 0.9.8y (Affected 0.9.8x, 0.9.8w, 0.9.8v, 0.9.8u, 0.9.8t, 0.9.8s, 0.9.8r, 0.9.8q, 0.9.8p, 0.9.8o, 0.9.8n, 0.9.8m, 0.9.8l, 0.9.8k, 0.9.8j, 0.9.8i, 0.9.8h, 0.9.8g, 0.9.8f, 0.9.8d, 0.9.8c, 0.9.8b, 0.9.8a, 0.9.8)
