Fix a side-channel attack on data-dependent timing variations in modular exponentiation, which can potentially lead to an information leak. (CVE-2015-0837 __)
Fix a side-channel attack which can potentially lead to an information leak. (CVE-2014-3591 __)
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 __, which was fixed in ALAS-2014-278. (CVE-2014-5270 __)
Run yum update libgcrypt to update your system.
