CVE-2025-52584

Code execution via malformed XE file parsing

Published Aug 18, 2025 · Updated Aug 19, 2025

Heap-based buffer overflow in Ashlar-Vellum CAD products before 12.6.1204.204 allows attackers to execute code through a crafted XE file. The published record identifies the XE parser and missing input validation but does not disclose the specific field or allocation operation that overruns the heap buffer. Exploitation requires a user to open the crafted file, and resulting code runs with the current process's privileges.
