Debian DLA-2573-1 : libzstd security update

high Nessus Plugin ID 146725

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that zstd, a compression utility, was vulnerable to a race condition: it temporarily exposed, during a very short timeframe, a world-readable version of its input even if the original file had restrictive permissions.

For Debian 9 stretch, this problem has been fixed in version 1.1.2-1+deb9u1.

We recommend that you upgrade your libzstd packages.

For the detailed security status of libzstd please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/libzstd

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 libzstd-dev, libzstd1, and zstd packages.
