DSA-4859-1 libzstd -- security update
- Date Reported:
- 20 Feb 2021
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 982519.
- More information:
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.
