Description Srikanth Balasubramanian 2026-08-25 10:13:04 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Heap buffer overflow in PostgreSQL to_char(timestamptz) allows the party choosing the timezone to execute arbitrary code as the operating system user running the database, via a long POSIX timezone abbreviation.  Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
