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...

Using timing attacks to bypass intrusion detection

It's possible to use difference in timing, for example packet reasembly timeouts, of target system and IDS to bypass detection. As workaround, timing parameters of IDS should be configured to match timing parameters of protected system...

security flaw

Hyper-Threading technology, as used in FreeBSD and other operating systems that are run on Intel Pentium and other processors, allows local users to use a malicious thread to create covert channels, monitor the execution of other threads, and obtain sensitive information such as cryptographic key...

CVE-2005-1797

The CVE describes a timing-side-channel vulnerability in AES (Rijndael) implementations: S-box lookups are difficult to perform in constant time, potentially allowing remote attackers to recover encryption keys. Documents cite the theoretical possibility of key recovery via timing analysis and re...

CVE-2005-1797

The design of Advanced Encryption Standard AES, aka Rijndael, allows remote attackers to recover AES keys via timing attacks on S-box lookups, which are difficult to perform in constant time in AES implementations...

CVE-2003-1562

sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled and using PAM keyboard-interactive authentication, does not insert a delay after a root login attempt with the correct password, which makes it easier for remote attackers to use timing differences to determine if the password...

security flaw

OpenSSL does not use RSA blinding by default, which allows local and remote attackers to obtain the server's private key by determining factors using timing differences on 1 the number of extra reductions during Montgomery reduction, and 2 the use of different integer multiplication algorithms...
