Package : libzstd
Debian Bug : 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 the stable distribution (buster), this problem has been fixed in
version 1.3.8+dfsg-3+deb10u2.
We recommend that you upgrade your libzstd packages.
For the detailed security status of libzstd please refer to
its security tracker page at:
