{"id":"UBUNTU-CVE-2026-119277","details":"MariaDB Connector/J is used to connect applications developed in Java to MariaDB and MySQL databases. From 3.0.0 until 3.3.7, 3.4.5, and 3.5.11, decoders for OK packet session-state blocks, column definition packets, text row data, or binary row data used server-declared lengths without confirming that the requested bytes remained in the receive buffer. The decoders could position reads, create sub-buffers, or decode strings beyond the packet boundary. A malicious or compromised server, or a machine-in-the-middle attacker, could trigger unchecked ArrayIndexOutOfBoundsException or IllegalArgumentException failures inside JDBC calls and terminate connection handling. This issue is fixed in versions 3.3.7, 3.4.5, and 3.5.11.","modified":"2026-10-31T03:30:10.423984713Z","published":"2026-10-30T00:00:00Z","upstream":["CVE-2026-119277"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-119277"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-119277"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/49c92adfcf816853e324031ba9762a69444cfd12"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/52538206298db39062ad67939f1446b767cacde4"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/commit/ea8c7b6537e50053444188a9a3fd9cae99550f56"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.3.7"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.4.5"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.5.11"},{"type":"REPORT","url":"https://github.com/mariadb-corporation/mariadb-connector-j/security/advisories/GHSA-wfxr-v78w-p49r"}],"affected":[{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3.0-1~18.04"],"ecosystem_specific":{"binaries":[{"binary_name":"libmariadb-java","binary_version":"2.3.0-1~18.04"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119277.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.2-1build2","2.5.3-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmariadb-java","binary_version":"2.5.3-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119277.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.2-1","2.7.4-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.7.4-1","binary_name":"libmariadb-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119277.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.6-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmariadb-java","binary_version":"2.7.6-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119277.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.6-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.7.6-1build1","binary_name":"libmariadb-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119277.json"}},{"package":{"name":"mariadb-connector-java","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/mariadb-connector-java?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.6-1","2.7.6-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmariadb-java","binary_version":"2.7.6-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119277.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
