CVE-2003-0147

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...

[ADVISORY] Timing Attack on OpenSSL

OpenSSL v0.9.7a and 0.9.6i vulnerability ---------------------------------------- Researchers have discovered a timing attack on RSA keys, to which OpenSSL is generally vulnerable, unless RSA blinding has been turned on. Typically, it will not have been, because it is not easily possible to do so...

qpopper timing analysis on to determine if a username exists on a system

Hello, during development of a pop3 tool I found an issue that makes it possible for any user to check the validity of a user on a target system. If a user is valid and an invalid password has been supplied, then the system waits 10 seconds until it sends a disconnect message and disconnect. If t...

Vulnerability in OpenSSL

Dan Boneh and I have been researching timing attacks against software crypto libraries. Timing attacks are usually used to attack weak computing devices such as smartcards. We've successfully developed and mounted timing attacks against software crypto libraries running on general purpose PC's. W...

OpenSSL < 0.9.6j / 0.9.7b Multiple Vulnerabilities

According to its banner, the remote host is using a version of OpenSSL older than 0.9.6j or 0.9.7b. This version is vulnerable to a timing-based attack that could allow an attacker to guess the content of fixed data blocks and may eventually be able to guess the value of the private RSA key of th...
