CVE-2009-0068: Freedesktop Xdg-Utils

Medium severity, CVSS 6.8. EPSS: 2.2% chance of exploitation in the next 30 days.

Interaction error in xdg-open allows remote attackers to execute arbitrary code by sending a file with a dangerous MIME type but using a safe type that Firefox sends to xdg-open, which causes xdg-open to process the dangerous file type through automatic type detection, as demonstrated by overwriting the .desktop file.

Affected products
