Debian DLA-1405-1 : libgcrypt20 security update

Low Nessus Plugin ID 110814

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that Libgcrypt is prone to a local side-channel attack allowing recovery of ECDSA private keys.

For Debian 8 'Jessie', these problems have been fixed in version 1.6.3-2+deb8u5.

We recommend that you upgrade your libgcrypt20 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.
