Description OSIDB Bzimport 2026-11-12 14:33:38 UTC 
Integer wraparound in PostgreSQL generation memory contexts allows a database user to execute arbitrary code as the operating system user running the database, via freeing an allocation larger than 1 GB and causing its block to be reused for smaller chunks whose back-pointer offset cannot represent that position.  Within major versions 16-18, minor versions before PostgreSQL 18.7, 17.12, and 16.16 are affected.  Versions before PostgreSQL 16 are unaffected.
