GnuPG / libcrypt information leakage
SecurityVulns ID:13961
Threat Level:
Description:ElGamal subkeys can be leaked via side-channel.
Affected:GNU : GnuPG 1.4
 LIBCRYPT : libgcrypt 1.5
CVE:CVE-2014-5270 (Libgcrypt before 1.5.4, as used in GnuPG and other products, does not properly perform ciphertext normalization and ciphertext randomization, which makes it easier for physically proximate attackers to conduct key-extraction attacks by leveraging the ability to collect voltage data from exposed metal, a different vector than CVE-2013-4576.)
