{"id":"UBUNTU-CVE-2025-49146","details":"pgjdbc is an open source postgresql JDBC Driver. From 42.7.4 and until 42.7.7, when the PostgreSQL JDBC driver is configured with channel binding set to required (default value is prefer), the driver would incorrectly allow connections to proceed with authentication methods that do not support channel binding (such as password, MD5, GSS, or SSPI authentication). This could allow a man-in-the-middle attacker to intercept connections that users believed were protected by channel binding requirements. This vulnerability is fixed in 42.7.7.","modified":"2026-05-20T16:23:32.776254664Z","published":"2025-06-11T15:15:00Z","upstream":["CVE-2025-49146"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-49146"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-49146"},{"type":"REPORT","url":"https://github.com/pgjdbc/pgjdbc/security/advisories/GHSA-hq9p-pm7w-8p54"},{"type":"REPORT","url":"https://github.com/pgjdbc/pgjdbc/commit/9217ed16cb2918ab1b6b9258ae97e6ede244d8a0"}],"affected":[{"package":{"name":"libpgjava","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.2-1002-1"],"ecosystem_specific":{"binaries":[{"binary_version":"9.2-1002-1","binary_name":"libpg-java"},{"binary_version":"9.2-1002-1","binary_name":"libpostgresql-jdbc-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-49146.json"}},{"package":{"name":"libpgjava","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.2-1002-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpg-java","binary_version":"9.2-1002-1"},{"binary_name":"libpostgresql-jdbc-java","binary_version":"9.2-1002-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-49146.json"}},{"package":{"name":"libpgjava","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.4.1212-1","9.4.1212-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpostgresql-jdbc-java","binary_version":"9.4.1212-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-49146.json"}},{"package":{"name":"libpgjava","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["42.2.6-1","42.2.8-1","42.2.9-1","42.2.10-1","42.2.10-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpostgresql-jdbc-java","binary_version":"42.2.10-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-49146.json"}},{"package":{"name":"libpgjava","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["42.2.23-1","42.2.24-1","42.3.1-1","42.3.2-1","42.3.3-1"],"ecosystem_specific":{"binaries":[{"binary_version":"42.3.3-1","binary_name":"libpostgresql-jdbc-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-49146.json"}},{"package":{"name":"libpgjava","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["42.5.4-1","42.6.0-2","42.7.0-1","42.7.1-1","42.7.2-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpostgresql-jdbc-java","binary_version":"42.7.2-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-49146.json"}},{"package":{"name":"libpgjava","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["42.7.5-1","42.7.5-2","42.7.7-1"],"ecosystem_specific":{"binaries":[{"binary_version":"42.7.7-1","binary_name":"libpostgresql-jdbc-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-49146.json"}},{"package":{"name":"libpgjava","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libpgjava?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["42.7.7-1","42.7.8-1","42.7.8-2","42.7.9-1","42.7.10-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libpostgresql-jdbc-java","binary_version":"42.7.10-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-49146.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
