Debian Security Advisory DSA-4850-1 security@debian.org
https://www.debian.org/security/ Sebastien Delafond
February 10, 2021 https://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : libzstd
Debian Bug : 981404
It was discovered that zstd, a compression utility, temporarily
exposed 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+deb10u1.
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
