CWEhttps://cwe.mitre.org/data/definitions/191.html

A code execution vulnerability exists in the DL_Dxf::handleLWPolylineData functionality of Ribbonsoft dxflib 3.17.0. A specially-crafted .dxf file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.

Weakness

The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
