Debian DLA-1080-1 : gnupg security update

medium Nessus Plugin ID 102888

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

See https://eprint.iacr.org/2017/627 for details.

For Debian 7 'Wheezy', these problems have been fixed in version 1.4.12-7+deb7u9.

We recommend that you upgrade your gnupg packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
