Description
Integer wraparound in PostgreSQL 32-bit builds of pltcl and plperl allows an object creator to cause the server to undersize an allocation and write out-of-bounds via crafted function bodies. This may execute arbitrary code as the operating system user running the database. CVE-2026-6473 had fixed similar problems. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
