Threats tagged 'ghsa-vwp2-2ffq-7j23'

A use-after-free vulnerability in PostgreSQL's expanded-record domain checks allows an object creator to execute arbitrary code with the privileges of the operating system user running the database. This occurs due to repeated domain checks over a composite type that reuse a dangling memory-context pointer. Versions prior to PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
