CVE-2023-41915

PMI has been used for quite some time as a means of exchanging wireup information needed for interprocess communication.

Security Fix(es):

OpenPMIx PMIx before 4.2.6 and 5.0.x before 5.0.1 allows attackers to obtain ownership of arbitrary files via a race condition during execution of library code with UID 0.(CVE-2023-41915)

The Process Management Interface (PMI) provides process management functions for MPI implementations. PMI Exascale (PMIx) provides an extended version of the PMI standard specifically designed to support clusters up to and including exascale sizes.

Security Fix(es):

• pmix: race condition allows attackers to obtain ownership of arbitrary files (CVE-2023-41915)

• CVE-2023-41915: prevent attackers from obtaining ownership of arbitrary files by fixing race condition during execution of library code with UID 0

OpenPMIx PMIx before 4.2.6 and 5.0.x before 5.0.1 allows attackers to obtain ownership of arbitrary files via a race condition during execution of library code with UID 0.

This update fixes a race condition allowing attackers to obtain ownership of arbitrary files (CVE-2023-41915).

These are all security issues fixed in the libmca_common_dstore1-3.2.3-11.1 package on the GA media of openSUSE Tumbleweed.

This update for pmix fixes the following issues:

• CVE-2023-41915: Fixed a potential vulnerability where a chown may follow a user-created link (bsc#1215190).

• Install pmix-plugin-munge if munge is installed.

Francois Diakhate discovered that PMIx did not properly handle race conditions in the pmix library, which could lead to unwanted privilege escalation. An attacker could possibly use this issue to obtain ownership of an arbitrary file on the filesystem, under the default configuration of the application.
