Threats tagged 'ghsa-ccfq-qwmr-4cgg'

A use-after-free vulnerability exists in the PostgreSQL pltcl extension that allows an object creator to execute arbitrary code as the operating system user running the database. This occurs via a domain CHECK constraint that re-enters the Tcl interpreter and manipulates a string that is still in use during result conversion. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
