CVE-2023-50188

Code execution via uninitialized SKP parser memory

Published May 3, 2024 · Updated Aug 2, 2024

Use of an uninitialized variable in Trimble SketchUp Viewer 22.0.354 allows remote attackers to execute code through a crafted SKP file. The SKP parser accesses memory before properly initializing it, causing the current process to operate on indeterminate data. Exploitation requires a user to visit a malicious page or open a malicious SKP file, after which code runs with the current process's privileges.
