Application crash via oversized preset name
Published Mar 21, 2026 · Updated Mar 21, 2026
Out-of-bounds write in Tomabo MP4 Converter 3.25.22 allows local users to crash the application through an oversized preset name. The preset editor accepts a 10,000-character Name value when Add Preset is used and writes beyond the intended buffer after Reset All is clicked. Exploitation requires interactive access to the Windows application and interrupts only that application process.
