- Vendor: Delta Electronics
- Equipment: DOPSoft 2
- Vulnerabilities: Stack-based Buffer Overflow, Out-of-Bounds Write, Heap-based Buffer Overflow
2. RISK EVALUATION
Successful exploitation of these vulnerabilities may allow arbitrary code execution.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following versions of DOPSoft 2 are affected:
- DOPSoft 2: Version 2.00.07 and prior
3.2 VULNERABILITY OVERVIEW
The affected application lacks proper validation of user-supplied data when parsing specific project files. This could lead to a stack-based buffer overflow while trying to copy to a buffer during font string handling. An attacker could leverage this vulnerability to execute code in the context of the current process.
The affected application lacks proper validation of user-supplied data when parsing specific project files. This could result in multiple out-of-bounds write instances. An attacker could leverage this vulnerability to execute code in the context of the current process.
