CVE-2025-71176
Description
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.
Statement
This vulnerability is rated Moderate for Red Hat products. The flaw in pytest allows a local attacker to cause a denial of service or potentially gain privileges by manipulating temporary directories in /tmp. This primarily affects systems where pytest is installed and executed by local users.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
