NVD Description
Note: Versions mentioned in the description apply only to the upstream postgresql:12/postgresql-private-libs package and not the postgresql:12/postgresql-private-libs package as distributed by RHEL.
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.
