Mandrake Linux Security Advisory : openssl (MDKSA-2006:161)

Daniel Bleichenbacher recently described an attack on PKCS 1 v1.5 signatures where an RSA key with a small exponent used could be vulnerable to forgery of a PKCS 1 v1.5 signature signed by that key. Any software using OpenSSL to verify X.509 certificates is potentially vulnerable to this issue, a...

Debian DSA-1210-1 : mozilla-firefox - several vulnerabilities

RSA Signature Forgery — Mozilla

Philip Mackenzie and Marius Schilder of Google informed us of Daniel Bleichenbacher's recent presentation of a common implementation error in RSA signature verification, a failure to account for extra data in the signature. For signatures with a small exponent such as 3 it is possible for an...

SUSE-SA:2003:024: openssl

The remote host is missing the patch for the advisory SUSE-SA:2003:024 openssl. Researchers from the University of Stanford have discovered certain weaknesses in OpenSSL's RSA decryption algorithm. It allows remote attackers to compute the private RSA key of a server by observing its timing...

SSL/TLS implementations disclose side channel information via PKCS #1 v1.5 version number extension

Overview SSL/TLS implementations that respond distinctively to an incorrect PKCS 1 v1.5 encoded SSL/TLS version number expose the premaster secret to a modified Bleichenbacher attack. An attacker could decrypt a given SSL/TLS session or forge a signature on behalf of a vulnerable application's...
