Description Murray McAllister 2013-12-16 00:31:32 UTC
It was found that GnuPG was vulnerable to side-channel attacks via acoustic cryptanalysis. An attacker in close range to a target system that is decrypting ciphertexts could possibly use this flaw to recover the RSA secret key from that system.

This issue affects GnuPG version 1.4. It does not affect the gnupg2 packages in Red Hat Enterprise Linux 5 and 6, and Fedora.

Comment 9 Murray McAllister 2013-12-18 05:52:35 UTC

Red Hat would like to thank Werner Koch of GnuPG upstream for reporting this issue. Upstream acknowledges Genkin, Shamir, and Tromer as the original reporters.

Comment 12 Vincent Danen 2013-12-18 20:10:23 UTC
This is fixed in upstream 1.4.16.
