Summary
OpenSSL is prone to RSA signature forgery.
Insight
Insight
OpenSSL, 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 X.509 and other certificates that use PKCS #1.
Affected Software
Affected Software
OpenSSL 0.9.7 through 0.9.7j and 0.9.8 through 0.9.8b.
Detection Method
Detection Method
Checks if a vulnerable version is present on the target host.
Solution
Solution
Update to version 0.9.7k, 0.9.8c or later.
