OpenSSL PKCS Padding RSA Signature Forgery Vulnerability
OpenSSL is prone to a vulnerability that may allow an attacker to forge an RSA signature. The attacker may be able to forge a PKCS #1 v1.5 signature when an RSA key with exponent 3 is used. An attacker may exploit this issue to sign digital certificates or RSA keys and take advantage of trust relationships that depend on these credentials, possibly posing as a trusted party and signing a certificate or key. All versions prior to and including OpenSSL 0.9.7j and 0.9.8b are affected by this vulnerability. Updates are available. |
