An update for libpq is now available for openEuler-24.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-1514 Final 1.0 1.0 2026-03-06 Initial 2026-03-06 2026-03-06 openEuler SA Tool V1.0 2026-03-06 libpq security update An update for libpq is now available for openEuler-24.03-LTS-SP3 PostgreSQL is a powerful, open source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads. This package provides the essential shared library for any PostgreSQL client program or interface. Security Fix(es): 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. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected.(CVE-2026-2003) 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. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected.(CVE-2026-2004) Heap buffer overflow in PostgreSQL pgcrypto allows a ciphertext provider to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected.(CVE-2026-2005) 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. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected.(CVE-2026-2006) An update for libpq is now available for master/openEuler-22.03-LTS-SP4/openEuler-24.03-LTS/openEuler-24.03-LTS-Next/openEuler-24.03-LTS-SP1/openEuler-24.03-LTS-SP2/openEuler-24.03-LTS-SP3. openEuler Security has rated this update as having a security impact of high.
