These client programs can be located on the same machine as the\nPostgreSQL server, or on a remote machine that accesses a PostgreSQL server\nover a network connection.  The PostgreSQL server can be found in the\npostgresql-server sub-package.\r\n\r\n\nSecurity Fix(es):\n\nImproper 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)\n\nMissing 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)\n\nHeap 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)\n\nMissing 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)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP2","name":"postgresql","purl":"pkg:rpm/openEuler/postgresql&distro=openEuler-24.03-LTS-SP2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"15.17-1.oe2403sp2"}]}],"ecosystem_specific":{"aarch64":["postgresql-15.17-1.oe2403sp2.aarch64.rpm","postgresql-contrib-15.17-1.oe2403sp2.aarch64.rpm","postgresql-debuginfo-15.17-1.oe2403sp2.aarch64.rpm","postgresql-debugsource-15.17-1.oe2403sp2.aarch64.rpm","postgresql-docs-15.17-1.oe2403sp2.aarch64.rpm","postgresql-llvmjit-15.17-1.oe2403sp2.aarch64.rpm","postgresql-plperl-15.17-1.oe2403sp2.aarch64.rpm","postgresql-plpython3-15.17-1.oe2403sp2.aarch64.rpm","postgresql-pltcl-15.17-1.oe2403sp2.aarch64.rpm","postgresql-private-devel-15.17-1.oe2403sp2.aarch64.rpm","postgresql-private-libs-15.17-1.oe2403sp2.aarch64.rpm","postgresql-server-15.17-1.oe2403sp2.aarch64.rpm","postgresql-server-devel-15.17-1.oe2403sp2.aarch64.rpm","postgresql-static-15.17-1.oe2403sp2.aarch64.rpm","postgresql-test-15.17-1.oe2403sp2.aarch64.rpm"],"noarch":["postgresql-test-rpm-macros-15.17-1.oe2403sp2.noarch.rpm"],"src":["postgresql-15.17-1.oe2403sp2.src.rpm"],"x86_64":["postgresql-15.17-1.oe2403sp2.x86_64.rpm","postgresql-contrib-15.17-1.oe2403sp2.x86_64.rpm","postgresql-debuginfo-15.17-1.oe2403sp2.x86_64.rpm","postgresql-debugsource-15.17-1.oe2403sp2.x86_64.rpm","postgresql-docs-15.17-1.oe2403sp2.x86_64.rpm","postgresql-llvmjit-15.17-1.oe2403sp2.x86_64.rpm","postgresql-plperl-15.17-1.oe2403sp2.x86_64.rpm","postgresql-plpython3-15.17-1.oe2403sp2.x86_64.rpm","postgresql-pltcl-15.17-1.oe2403sp2.x86_64.rpm","postgresql-private-devel-15.17-1.oe2403sp2.x86_64.rpm","postgresql-private-libs-15.17-1.oe2403sp2.x86_64.rpm","postgresql-server-15.17-1.oe2403sp2.x86_64.rpm","postgresql-server-devel-15.17-1.oe2403sp2.x86_64.rpm","postgresql-static-15.17-1.oe2403sp2.x86_64.rpm","postgresql-test-15.17-1.oe2403sp2.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1495"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2003"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2004"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2005"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2006"}],"database_specific":{"severity":"High"}}
