Description
This security bulletin contains information about 1 security vulnerability.
1) Information disclosure (CVE-ID: CVE-2014-5270)
The vulnerability allows a local non-authenticated attacker to gain access to sensitive information.
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.
