CVE-2013-4242

CVE-2013-4242 affects GnuPG before 1.4.14 and Libgcrypt before 1.5.3 (as used in GnuPG 2.0.x), enabling a local user to obtain private RSA keys via a cache side-channel (Flush+Reload) on the L3 cache. The root cause is a cache side-channel leak in the RSA key handling within GnuPG/Libgcrypt. Docu...

FreeBSD : gnupg -- side channel attack on RSA secret keys (80771b89-f57b-11e2-bf21-b499baab0cbe)

A Yarom and Falkner paper reports : Flush+Reload is a cache side-channel attack that monitors access to data in shared pages. In this paper we demonstrate how to use the attack to extract private encryption keys from GnuPG. The high resolution and low noise of the Flush+Reload attack enables a sp...
