Summary
Vulnerability in openjdk-9 (UBUNTU-CVE-2026-10037). Successful exploitation can lead to full system takeover. Mitigation: upgrade to 3.70+nmu1ubuntu1.22.04.1 or later.
Original description
The description as published by the source.
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.
