Package        : pmix
Version        : 3.1.2-3+deb10u1
CVE ID         : CVE-2023-41915
Debian Bug     : 1051729

It was discovered that there was an arbitrary file overwrite
vulnerability in pmix, a library used in parallel/cluster computing.

Attackers could have obtained ownership of arbitrary files via a
symlink-related race condition during execution of library code with
UID 0. 

For Debian 10 buster, this problem has been fixed in version
3.1.2-3+deb10u1.

We recommend that you upgrade your pmix packages.
