Cryptographic Issues

CVE-2006-4339

Medium
5.3/10

Summary

In OpenSSL, when using an RSA key with exponent 3, it 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". This vulnerability affects versions through OpenSSL_0_9_7j, and OpenSSL_0_9_8-beta1 through OpenSSL_0_9_8b.
