Doc Text:
A flaw was found in pytest. This vulnerability allows local users to exploit insecure temporary directory handling, specifically the reliance on predictable directory names in /tmp/pytest-of-{user}. An attacker can leverage this to cause a denial of service (DoS) or potentially gain elevated privileges on the system.

Description OSIDB Bzimport 2026-01-22 06:01:25 UTC
pytest through 9.0.2 on UNIX relies on directories with the /tmp/pytest-of-{user} name pattern, which allows local users to cause a denial of service or possibly gain privileges.
