Description OSIDB Bzimport 2026-11-12 14:32:29 UTC
Use after free in PostgreSQL plperl allows an object creator to execute arbitrary code as the operating system user running the database, via reentrant return_next() calls.  Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
