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...

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-2006-5484

CVE-2006-5484 describes a cryptographic flaw in SSH Tectia Client/Server/Connector (5.1.0 and earlier) and Manager (2.2.0 and earlier), 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...

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...

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....
