Hi,

You are receiving an AlmaLinux Security update email because you subscribed to receive errata
notifications from AlmaLinux.

AlmaLinux: 10
Type: Security
Severity: Important
Release date: 2026-05-26

Summary:

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: PostgreSQL pg_trgm heap buffer overflow writes pattern onto server memory
(CVE-2026-2007)
  * postgresql: PostgreSQL oidvector discloses a few bytes of memory (CVE-2026-2003)
  * postgresql: PostgreSQL missing validation of multibyte character length executes arbitrary code
(CVE-2026-2006)
  * postgresql: PostgreSQL intarray missing validation of type of input to selectivity estimator
executes arbitrary code (CVE-2026-2004)
  * postgresql: PostgreSQL pgcrypto heap buffer overflow executes arbitrary code (CVE-2026-2005)
