- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 981404, 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 Debian 9 stretch, this problem has been fixed in version 1.1.2-1+deb9u1.
We recommend that you upgrade your libzstd packages.
