OpenSSL 1.0.1 < 1.0.1e Information Disclosure
According to its banner, the remote web server is running a version of OpenSSL 1.0.1 prior to 1.0.1e. The OpenSSL library is, therefore, reportedly affected by an incomplete fix for CVE-2013-0169. An error exists related to the SSL/TLS/DTLS protocols, CBC mode encryption and response time. An...
CVE-2013-1624
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 attack...
CVE-2013-0169
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...

Three Questions for Billy Brumley on the OpenSSL Timing Attack
Timing attacks have been a problem for designers of cryptosystems–as well as for people implementing those systems–for a long time. They’ve plagued just about every popular system, and although practical attacks have been demonstrated many times, the problem and what can be done to defend against...
CVE-2011-0910
The cookie implementation in Vanilla Forums before 2.0.17.6 makes it easier for remote attackers to spoof signed requests, and consequently obtain access to arbitrary user accounts, via HMAC timing attacks...

CVE-2011-0910
Vanilla Forums vulnerability CVE-2011-0910 affects versions before 2.0.17.6. The cookie implementation allows remote attackers to spoof signed requests and potentially gain access to arbitrary user accounts via HMAC timing attacks. Root cause: flawed cookie handling enabling timing-based forgery....
Gaining Precision in Information Leakage Attacks
It’s hard to narrow down your life’s work into one interesting event or tidbit. Even picking 10 would be tough. So instead of picking something I am well-known for, I wanted to look for something I had a lot of fun coming up with that you probably didn’t read. I’ve always been interested in...
