Check for the version of the gnupg package Detailed Explanation for this Vulnerability Assessment The remote host is missing the patch for the advisory FEDORA-2003-025 (gnupg). GnuPG (GNU Privacy Guard) is a GNU utility for encrypting data and creating digital signatures. GnuPG has advanced key management capabilities and is compliant with the proposed OpenPGP Internet standard described in RFC2440. Since GnuPG doesn't use any patented algorithm, it is not compatible with any version of PGP2 (PGP2.x uses only IDEA for symmetric-key encryption, which is patented worldwide). Update Information: Phong Nguyen identified a severe bug in the way GnuPG creates and uses ElGamal keys, when those keys are used both to sign and encrypt data. This vulnerability can be used to trivially recover the private key. While the default behavior of GnuPG when generating keys does not lead to the creation of unsafe keys, by overriding the default settings an unsafe key could have been created. If you are using ElGamal keys, you should revoke those keys immediately. The packages included in this update do not make ElGamal keys safe to use they merely include a patch by David Shaw that disables functions that would generate or use ElGamal keys for encryption.
