Red Hat Security Advisory: postgresql16 security update
PostgreSQL is an advanced Object-Relational database management system (DBMS). The base postgresql package contains the client programs that you'll need to access a PostgreSQL DBMS server, as well as HTML documentation for the whole system. These client programs can be located on the same machine as the PostgreSQL server, or on a remote machine that accesses a PostgreSQL server over a network connection. The PostgreSQL server can be found in the postgresql-server sub-package. Security Fix(es): * postgresql: libpq undersizes allocations, via integer wraparound (CVE-2025-12818) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
This advisory addresses two vulnerabilities in PostgreSQL 16 on Red Hat Enterprise Linux 10. CVE-2025-12817 is a privilege check bypass where the CREATE STATISTICS command does not verify schema CREATE privileges, potentially allowing unauthorized actions. CVE-2025-12818 involves an integer wraparound in libpq causing undersized memory allocations, which could lead to memory corruption or related issues. Red Hat has released updated packages (version 16.11-1.el10_1) that fix these vulnerabilities. The advisory rates the security impact as moderate and provides updated RPM packages for various architectures and extended support versions.
Potential Impact
The vulnerabilities could allow unauthorized users to perform actions without proper schema CREATE privileges (CVE-2025-12817) and cause memory allocation errors due to integer wraparound in libpq (CVE-2025-12818). These issues may lead to privilege escalation or memory corruption, impacting the security and stability of PostgreSQL installations on affected Red Hat Enterprise Linux 10 systems.
Mitigation Recommendations
Red Hat has released an official security update for PostgreSQL 16 (version 16.11-1.el10_1) that addresses these vulnerabilities. Users should apply the update promptly following Red Hat's guidance at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official patch.
