Summary

CVE-2023-49797 affectes applications built with PyInstaller, a tool used to bundle Python applications and their dependencies. If an attacker can trick a user into replacing a temporary file with a symlink while the file is being deleted, they may delete files that the user does not have direct access to. This vulnerability only affects users running applications containing `matplotlib` or `win32com` as administrators, with a non-protected temporary directory. PyInstaller versions before `5.13.1` are susceptible to this issue, which can lead to data loss for the affected user. There are no known workarounds, and users are strongly advised to upgrade to the latest PyInstaller version to mitigate this risk.
