-------------------------------------------------------------------------

Package : postgresql-13 Version : 13.23-0+deb11u2 CVE ID : CVE-2026-2003 CVE-2026-2004 CVE-2026-2005 CVE-2026-2006 Debian Bug :

Multiple vulnerabilities were fixed in PostgreSQL, a popular database.

CVE-2026-2003

Fix CVE-2026-2003: Improper validation of type oidvector in PostgreSQL allows a database user to disclose a few bytes of server memory. We have not ruled out viability of attacks that arrange for presence of confidential information in disclosed bytes, but they seem unlikely.

CVE-2026-2004

Fix CVE-2026-2004: Missing validation of type of input in PostgreSQL intarray extension selectivity estimator function allows an object creator to execute arbitrary code as the operating system user running the database.

CVE-2026-2005

Fix CVE-2026-2005: Heap buffer overflow in PostgreSQL pgcrypto allows a ciphertext provider to execute arbitrary code as the operating system user running the database.

CVE-2026-2006

Fix CVE-2026-2006: Missing validation of multibyte character length in PostgreSQL text manipulation allows a database user to issue crafted queries that achieve a buffer overrun. That suffices to execute arbitrary code as the operating system user running the database.

For Debian 11 bullseye, these problems have been fixed in version 13.23-0+deb11u2.

We recommend that you upgrade your postgresql-13 packages.

For the detailed security status of postgresql-13 please refer to its security tracker page at:
