Multiple RSA implementations fail to properly handle signatures

Overview Multiple RSA implementations fail to properly handle RSA signatures. This vulnerability may allow an attacker to forge RSA signatures. Description RSA signatures are used to authenticate the source of a message. To prevent RSA signatures from being forged, messages are padded with data t...

openssl -- Incorrect PKCS#1 v1.5 padding validation in crypto(3)

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...

USN-339-1: OpenSSL vulnerability

Philip Mackenzie, Marius Schilder, Jason Waddle and Ben Laurie of Google Security discovered that the OpenSSL library did not sufficiently check the padding of PKCS 1 v1.5 signatures if the exponent of the public key is 3 which is widely used for CAs. This could be exploited to forge signatures...

OpenSSL RSA Signature Forgery Vulnerability

OpenSSL versions 0.9.7j and prior and 0.9.8b and prior contain a vulnerability that could allow an unauthenticated, remote attacker to successfully pass a forged X.509 certificate. The vulnerability could allow an unauthenticated, remote attacker to pass a forged Public-Key Cryptography Standards...

CVE-2006-4339

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...

CVE-2006-4339

CVE-2006-4339 affects OpenSSL versions prior to 0.9.7 and 0.9.8 before patches (0.9.7k, 0.9.8c) where using an RSA key with exponent 3 causes PKCS#1 padding to be removed before hash generation. This enables remote attackers to forge a PKCS#1 v1.5 signature signed by that RSA key and can prevent ...
