Package        : libgcrypt11
CVE ID         : CVE-2015-7511

Daniel Genkin, Lev Pachmanov, Itamar Pipman and Eran Tromer discovered
that the ECDH secret decryption keys in applications using the
libgcrypt11 library could be leaked via a side-channel attack.

See https://www.cs.tau.ac.IL/~tromer/ecdh/ for details.

For the oldstable distribution (wheezy), this problem has been fixed
in version 1.5.0-5+deb7u4.

We recommend that you upgrade your libgcrypt11 packages.
