Package        : libzstd
Version        : 1.1.2-1+deb9u1
Debian Bug     : 981404 982519

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/source-package/libzstd

Further information about Debian LTS security advisories, how to apply
these updates to your system and frequently asked questions can be
