Debian Security Advisory DSA-3960-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
September 01, 2017 https://www.debian.org/security/faq

Package : gnupg
CVE ID : CVE-2017-7526

Daniel J. Bernstein, Joachim Breitner, Daniel Genkin, Leon Groot
Bruinderink, Nadia Heninger, Tanja Lange, Christine van Vredendaal and
Yuval Yarom discovered that GnuPG is prone to a local side-channel
attack allowing full key recovery for RSA-1024.

For the oldstable distribution (jessie), this problem has been fixed
in version 1.4.18-7+deb8u4.

We recommend that you upgrade your gnupg packages.
