CVE-2013-0169

Published: 8 February 2013

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.

Notes

1.0.1d has incorrect fix. Use 1.0.1e:

regression bug: http://rt.openssl.org/Ticket/Display.html?id=2975&user=guest&pass=guest
1.0.1e still contains another regression:
another regression: http://rt.openssl.org/Ticket/Display.html?id=2984&user=guest&pass=guest
OpenSSL fix reverted by 1732-2 because of regression
(see: https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/1133333)
