CVE-2021-33897
A buffer overflow in Synthesia before 10.7.5567, when a non-Latin locale is used, allows user-assisted attackers to cause a denial of service (application crash) via a crafted MIDI file with malformed bytes.
Does this matter?
Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.
Description
A buffer overflow in Synthesia before 10.7.5567, when a non-Latin locale is used, allows user-assisted attackers to cause a denial of service (application crash) via a crafted MIDI file with malformed bytes. This file is mishandled during a deletion attempt. In Synthesia before 10.9, an improper path handling allows local attackers to cause a denial of service (application crash) via a crafted MIDI file with malformed bytes.
