CVE-2016-9951: n/a vulnerability

CVE-2016-9951: An issue was discovered in Apport before 2.20.4.

An issue was discovered in Apport before 2.20.4. A malicious Apport crash file can contain a restart command in `RespawnCommand` or `ProcCmdline` fields. This command will be executed if a user clicks the Relaunch button on the Apport prompt from the malicious crash file. The fix is to only show the Relaunch button on Apport crash files generated by local systems. The Relaunch button will be hidden when crash files are opened directly in Apport-GTK.

Security readout for executives and security teams

CVE-2016-9951 affects Apport before 2.20.4, Ubuntu’s crash-reporting tool. A crafted crash file could cause command execution if a user opened it in Apport and clicked Relaunch. The documented fix hides Relaunch for crash files opened directly rather than generated locally. Exposure is mainly Ubuntu desktop or workstation environments using vulnerable Apport versions before 2.20.4 where users can receive or open untrusted crash files. Treat this as a targeted desktop-risk issue, not an internet-wide emergency. Prioritize patching Ubuntu workstations, developer desktops, and shared systems where users may handle external files. Mitigation focus: Update Apport to version 2.20.4 or a vendor-fixed package.; Apply Ubuntu advisory USN-3157-1 where applicable.; Avoid opening untrusted Apport crash files directly..
