OpenSSL ASN.1 parser insecure memory deallocation

Overview A vulnerability in the way OpenSSL deallocates memory used to store ASN.1 structures could allow a remote attacker to execute arbitrary code with the privileges of the process using the OpenSSL library. Description OpenSSL implements the Secure Sockets Layer SSL and Transport Layer...

OpenSSL does not securely handle invalid public key when configured to ignore errors

Overview A vulnerability in the way OpenSSL handles invalid public keys in client certificate messages could allow a remote attacker to cause a denial of service. This vulnerability requires as a precondition that an application is configured to ignore public key decoding errors, which is typical...

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...

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...
