Daniel Genkin, Lev Pachmanov, Itamar Pipman and Eran Tromer discovered that
the ECDH secret decryption keys in applications using the libgcrypt20 library
could be leaked via a side-channel attack (CVE-2015-7511).

The libgcrypt package was also updated to include countermeasures against
Lenstra's fault attack on RSA Chinese Remainder Theorem optimization in RSA.
A signature verification step was updated to protect against leaks of private
keys in case of hardware faults or implementation errors in numeric
libraries. This issue is equivalent to the CVE-2015-5738 issue in gnupg.");
