{"id":"UBUNTU-CVE-2025-1948","details":"In Eclipse Jetty versions 12.0.0 to 12.0.16 included, an HTTP/2 client can specify a very large value for the HTTP/2 settings parameter SETTINGS_MAX_HEADER_LIST_SIZE. The Jetty HTTP/2 server does not perform validation on this setting, and tries to allocate a ByteBuffer of the specified capacity to encode HTTP responses, likely resulting in OutOfMemoryError being thrown, or even the JVM process exiting.","modified":"2026-05-20T16:20:23.719586938Z","published":"2025-05-08T18:15:00Z","upstream":["CVE-2025-1948"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-1948"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-1948"},{"type":"REPORT","url":"https://github.com/jetty/jetty.project/security/advisories/GHSA-889j-63jv-qhr8"},{"type":"REPORT","url":"https://github.com/jetty/jetty.project/issues/12690"}],"affected":[{"package":{"name":"jetty","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/jetty?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.1.26-1ubuntu1","6.1.26-1ubuntu1.1","6.1.26-1ubuntu1.2"],"ecosystem_specific":{"binaries":[{"binary_name":"jetty","binary_version":"6.1.26-1ubuntu1.2"},{"binary_name":"libjetty-extra","binary_version":"6.1.26-1ubuntu1.2"},{"binary_name":"libjetty-extra-java","binary_version":"6.1.26-1ubuntu1.2"},{"binary_name":"libjetty-java","binary_version":"6.1.26-1ubuntu1.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-1948.json"}},{"package":{"name":"jetty","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/jetty?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.1.26-5","6.1.26-5ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjetty-extra","binary_version":"6.1.26-5ubuntu0.1"},{"binary_name":"libjetty-extra-java","binary_version":"6.1.26-5ubuntu0.1"},{"binary_name":"libjetty-java","binary_version":"6.1.26-5ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-1948.json"}},{"package":{"name":"jetty9","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/jetty9?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.2.14-1"],"ecosystem_specific":{"binaries":[{"binary_name":"jetty9","binary_version":"9.2.14-1"},{"binary_name":"libjetty9-extra-java","binary_version":"9.2.14-1"},{"binary_name":"libjetty9-java","binary_version":"9.2.14-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-1948.json"}},{"package":{"name":"jetty9","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/jetty9?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.2.22-2","9.2.22-3","9.2.23-1","9.4.15-1~18.04.1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"jetty9","binary_version":"9.4.15-1~18.04.1ubuntu1"},{"binary_name":"libjetty9-extra-java","binary_version":"9.4.15-1~18.04.1ubuntu1"},{"binary_name":"libjetty9-java","binary_version":"9.4.15-1~18.04.1ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-1948.json"}},{"package":{"name":"jetty9","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/jetty9?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.4.18-2build2","9.4.26-1"],"ecosystem_specific":{"binaries":[{"binary_name":"jetty9","binary_version":"9.4.26-1"},{"binary_name":"libjetty9-extra-java","binary_version":"9.4.26-1"},{"binary_name":"libjetty9-java","binary_version":"9.4.26-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-1948.json"}},{"package":{"name":"jetty9","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/jetty9?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.4.39-3","9.4.44-2","9.4.44-3","9.4.44-4","9.4.45-1"],"ecosystem_specific":{"binaries":[{"binary_name":"jetty9","binary_version":"9.4.45-1"},{"binary_name":"libjetty9-extra-java","binary_version":"9.4.45-1"},{"binary_name":"libjetty9-java","binary_version":"9.4.45-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-1948.json"}},{"package":{"name":"jetty9","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/jetty9?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.4.51-2","9.4.53-1"],"ecosystem_specific":{"binaries":[{"binary_name":"jetty9","binary_version":"9.4.53-1"},{"binary_name":"libjetty9-extra-java","binary_version":"9.4.53-1"},{"binary_name":"libjetty9-java","binary_version":"9.4.53-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-1948.json"}},{"package":{"name":"jetty9","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/jetty9?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.4.56-1","9.4.57-1"],"ecosystem_specific":{"binaries":[{"binary_name":"jetty9","binary_version":
