CVE-2014-3591

Name of the Vulnerable Software and Affected Versions Libgcrypt versions prior to 1.6.3 GnuPG versions prior to 1.4.19

Description The issue concerns the lack of ciphertext blinding for Elgamal decryption, allowing physically proximate attackers to obtain the server's private key. This is achieved by determining factors using crafted ciphertext and analyzing the fluctuations in the electromagnetic field during multiplication.

Recommendations For Libgcrypt versions prior to 1.6.3, update to version 1.6.3 or later to resolve the issue. For GnuPG versions prior to 1.4.19, update to version 1.4.19 or later to resolve the issue.
