Description Vincent Danen 2013-02-06 11:49:04 EST

In addition to the fix for CVE-2013-0169, PolarSSL 1.2.5 corrects the following problem:

"PolarSSL ... it does not perform any MAC check if this
sanity check fails, but instead exits immediately. This would
render the implementation vulnerable to a simple timing-based
distinguishing attack." (requires a non-default configuration with
"TLS alert messages when decryption errors are encountered")
