## Overview

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.

## Affected packages

- `pytest < 9.0.3`

## Remediation

Upgrade to a patched release:

- `pytest 9.0.3`
