Uncaught exceptions in PostgreSQL plperl allow an object creator to cause use of a stale sigjmp_buf, via a tied Perl object, or a Perl object whose overloaded conversion throws while plperl is handling another error. We have not ruled out arbitrary code execution on some platform. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.

Ein Angreifer kann mehrere Schwachstellen in PostgreSQL ausnutzen, um beliebigen Code auszuführen, Berechtigungen zu erweitern, Sicherheitsmaßnahmen zu umgehen, SQL-Injection durchzuführen, Daten zu manipulieren und offenzulegen oder einen Denial-of-Service-Zustand zu verursachen.
