Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
pytest versions before 9.0.3 have vulnerable tmpdir handling on UNIX systems, where the directories it uses under the /tmp/pytest-of-{user} name pattern can be abused. A local user can exploit this to cause a denial of service or possibly gain privileges. Upgrade pytest to version 9.0.3 or later.
