Name of the Vulnerable Software and Affected Versions Zim versions 0.72.1 and earlier

Description The issue allows a malicious user to predict and create Zim's temporary directories, preventing other users from starting Zim and resulting in a denial of service.

Recommendations For versions 0.72.1 and earlier, consider implementing a randomization mechanism for temporary directory names to prevent predictability and potential denial of service attacks. As a temporary workaround, restrict access to the temporary directory creation process to minimize the risk of exploitation.
