Last modified Jun 17, 2026

CVE-2018-8839 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. Delta PMSoft versions 2.10 and prior have multiple stack-based buffer overflow vulnerabilities where a .ppm file can introduce a value larger than is readable by PMSoft's fixed-length stack buffer. This can cause the buffer to be overwritten, which may allow arbitrary code execution or cause the application to crash. EPSS estimates a 0.47% chance of exploitation in the next 30 days.
