Debian DLA-1931-2 : libgcrypt20 regression update

medium Nessus Plugin ID 129305

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that the fix to address an ECDSA timing attack in the libgcrypt20 cryptographic library was incomplete.

For Debian 8 'Jessie', this issue has been fixed in libgcrypt20 version 1.6.3-2+deb8u8. Thanks to Albert Chin-A-Young <[email protected]> for the report.

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.
