Advisory Released Date: 2025-12-08
Advisory Updated Date: 2025-12-08
Severity:
Medium
Issue Overview:
Integer wraparound in multiple PostgreSQL libpq client library functions allows an application input provider or network peer to cause libpq to undersize an allocation and write out-of-bounds by hundreds of megabytes. This results in a segmentation fault for the application using libpq. Versions before PostgreSQL 18.1, 17.7, 16.11, 15.15, 14.20, and 13.23 are affected. (CVE-2025-12818)
Affected Packages:
libpq
Issue Correction:
Run dnf update libpq --releasever 2023.9.20251208 or dnf update --advisory ALAS2023-2025-1299 --releasever 2023.9.20251208 to update your system.
