CVE-2024-10372: 
Homebrew vulnerability analysis and mitigation

A vulnerability has been identified in chidiwilliams buzz version 1.1.0, specifically affecting the downloadmodel function in the buzz/modelloader.py file. The vulnerability was disclosed on October 24, 2024, and is tracked as CVE-2024-10372. The issue stems from the use of insecure temporary file handling (GitHub Advisory).

The vulnerability arises from the use of the deprecated tempfile.mktemp() function, which is fundamentally insecure as it does not ensure exclusive access to temporary files. The function generates a unique filename but requires a separate operation to open the file, creating a potential race condition. The CVSS v3.1 base score is 3.6 (LOW) with the vector string CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:L (NVD).

The vulnerability primarily affects system availability and can potentially lead to code execution and data leaks. This occurs because malicious actors could replace the intended model with a compromised URL model during the window between temporary file name generation and file creation (GitHub Advisory).

The recommended fix is to replace the usage of tempfile.mktemp() with mkstemp(). This alternative function provides atomic file creation and ensures exclusive access to the temporary file (GitHub Advisory).
