Description OSIDB Bzimport 2026-05-14 14:02:10 UTC
Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds.  This may execute arbitrary code as the operating system user running the database.  In applications that pass gigabyte-scale user inputs to the relevant database functions, the application input provider may achieve a segmentation fault.  Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

Comment 2 David Raya 2026-06-08 07:30:51 UTC
I encountered this bug on Red Hat Enterprise Linux 9.5 and Fedora 41 (https://fnffree.io) with the latest postgresql-server packages. It triggers during bulk INSERT/UPDATE operations with large integer values, causing a segmentation fault due to integer overflow and out-of-bounds write.
