{"id":"UBUNTU-CVE-2026-10037","details":"A sandbox escape vulnerability exists in the OpenJDK packages provided in Ubuntu. The .jar MIME handlers installed by these packages execute files marked as executable when the mailcap package is installed. A compromised or malicious sandboxed application with access to the OpenURI portal via xdg-desktop-portal-gtk can write a malicious .jar file to the host file system, set its executable bit, and trigger the handler to execute arbitrary code outside of the sandbox environment.","modified":"2026-07-09T21:30:36.807927857Z","published":"2026-07-08T21:18:56Z","related":["USN-8518-1"],"upstream":["CVE-2026-10037"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-10037"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-10037"},{"type":"REPORT","url":"https://bugs.launchpad.net/ubuntu/+source/openjdk-25/+bug/2153100"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8518-1"}],"affected":[{"package":{"name":"openjdk-9","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/openjdk-9?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9~b88-1","9~b101-2ubuntu2","9~b102-1","9~b113-0ubuntu1","9~b114-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"openjdk-9-demo","binary_version":"9~b114-0ubuntu1"},{"binary_name":"openjdk-9-jdk","binary_version":"9~b114-0ubuntu1"},{"binary_name":"openjdk-9-jdk-headless","binary_version":"9~b114-0ubuntu1"},{"binary_version":"9~b114-0ubuntu1","binary_name":"openjdk-9-jre"},{"binary_name":"openjdk-9-jre-headless","binary_version":"9~b114-0ubuntu1"},{"binary_name":"openjdk-9-source","binary_version":"9~b114-0ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10037.json"}},{"package":{"name":"openjdk-13","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/openjdk-13?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["13+33-1","13.0.1+9-2","13.0.2+8-1","13.0.2+8-2","13.0.3+3-1ubuntu2","13.0.4+8-1~20.04","13.0.7+5-0ubuntu1~20.04"],"ecosystem_specific":{"binaries":[{"binary_name":"openjdk-13-demo","binary_version":"13.0.7+5-0ubuntu1~20.04"},{"binary_name":"openjdk-13-jdk","binary_version":"13.0.7+5-0ubuntu1~20.04"},{"binary_name":"openjdk-13-jdk-headless","binary_version":"13.0.7+5-0ubuntu1~20.04"},{"binary_version":"13.0.7+5-0ubuntu1~20.04","binary_name":"openjdk-13-jre"},{"binary_name":"openjdk-13-jre-headless","binary_version":"13.0.7+5-0ubuntu1~20.04"},{"binary_name":"openjdk-13-jre-zero","binary_version":"13.0.7+5-0ubuntu1~20.04"},{"binary_name":"openjdk-13-source","binary_version":"13.0.7+5-0ubuntu1~20.04"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10037.json"}},{"package":{"name":"openjdk-16","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/openjdk-16?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["16.0.1+9-1~20.04"],"ecosystem_specific":{"binaries":[{"binary_name":"openjdk-16-demo","binary_version":"16.0.1+9-1~20.04"},{"binary_name":"openjdk-16-jdk","binary_version":"16.0.1+9-1~20.04"},{"binary_name":"openjdk-16-jdk-headless","binary_version":"16.0.1+9-1~20.04"},{"binary_name":"openjdk-16-jre","binary_version":"16.0.1+9-1~20.04"},{"binary_name":"openjdk-16-jre-headless","binary_version":"16.0.1+9-1~20.04"},{"binary_name":"openjdk-16-jre-zero","binary_version":"16.0.1+9-1~20.04"},{"binary_version":"16.0.1+9-1~20.04","binary_name":"openjdk-16-source"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10037.json"}},{"package":{"name":"mailcap","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/mailcap?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.70+nmu1ubuntu1.22.04.1"}]}],"versions":["3.69ubuntu1","3.70ubuntu1","3.70+nmu1ubuntu1"],"ecosystem_specific":{"availability":"No
