CVE-2006-5484

SSH Tectia Client/Server/Connector 5.1.0 and earlier, Manager 2.2.0 and earlier, and other products, 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...

CVE-2006-5201

CVE-2006-5201 affects Sun Solaris components (notably NSS, NSS-based libraries, Java JDK/JRE, JSSE, IPSec/IKE, and related Sun products). The root cause is when using an RSA key with exponent 3 that removes PKCS #1 padding prior to hash generation, enabling remote attackers to forge a PKCS #1 v1....

CVE-2006-5201

Multiple packages on Sun Solaris, including 1 NSS; 2 Java JDK and JRE 5.0 Update 8 and earlier, SDK and JRE 1.4.x up to 1.4.212, and SDK and JRE 1.3.x up to 1.3.119; 3 JSSE 1.0.303 and earlier; 4 IPSec/IKE; 5 Secure Global Desktop; and 6 StarOffice, when using an RSA key with exponent 3, removes...

USN-348-1: GnuTLS vulnerability

The GnuTLS 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 without the need of the secret key...

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 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...

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...

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 ...
