RSA Signature Forgery — Mozilla

Philip Mackenzie and Marius Schilder of Google informed us of Daniel Bleichenbacher's recent presentation of a common implementation error in RSA signature verification, a failure to account for extra data in the signature. For signatures with a small exponent such as 3 it is possible for an...

mozilla -- multiple vulnerabilities

The Mozilla Foundation reports of multiple security issues in Firefox, Seamonkey, and Thunderbird. Several of these issues can probably be used to run arbitrary code with the privilege of the user running the program.

GLSA-200609-05 : OpenSSL, AMD64 x86 emulation base libraries: RSA signature forgery

The remote host is affected by the vulnerability described in GLSA-200609-05 OpenSSL, AMD64 x86 emulation base libraries: RSA signature forgery Daniel Bleichenbacher discovered that it might be possible to forge signatures signed by RSA keys with the exponent of 3. Impact : Since several CAs are...

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...

gnutls -- RSA Signature Forgery Vulnerability

Secunia reports: A vulnerability has been reported in GnuTLS, which can be exploited by malicious people to bypass certain security restrictions. The vulnerability is caused due to an error in the verification of certain signatures. If a RSA key with exponent 3 is used, it may be possible to forg...

OpenSSL, AMD64 x86 emulation base libraries: RSA signature forgery

Background OpenSSL is a toolkit implementing the Secure Sockets Layer, Transport Layer Security protocols and a general-purpose cryptography library. The x86 emulation base libraries for AMD64 contain a vulnerable version of OpenSSL. Description Daniel Bleichenbacher discovered that it might be...

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...

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 ...
