Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the DXF polyline import process. An attacker can cause application instability and system unavailability by tricking a user into opening a specially crafted DXF file. This is only exploitable if a user opens a malicious DXF file in a desktop environment where untrusted drawing files are processed.
Workaround
This vulnerability can be mitigated by restricting the processing of untrusted or unverified DXF documents and exercising caution when opening DXF files from untrusted sources.
