openssl signature forgery

OpenSSL before 0.9.7, 0.9.7 before 0.9.7k, and 0.9.8 before 0.9.8c, when using an RSA key with exponent 3, removes PKCS-1 padding before generating a hash, which allows remote attackers to forge a PKCS 1 v1.5 signature that is signed by that RSA key and prevents OpenSSL from correctly verifying...

FreeBSD : openssl -- Incorrect PKCS#1 v1.5 padding validation in crypto(3) (077c2dca-8f9a-11db-ab33-000e0c2e438a)

Problem Description When verifying a PKCS1 v1.5 signature, OpenSSL ignores any bytes which follow the cryptographic hash being signed. In a valid signature there will be no such bytes. Impact OpenSSL will incorrectly report some invalid signatures as valid. When an RSA public exponent of 3 is use...

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...
