Executive Summary

This vulnerability occurs in the plistlib module when loading a plist file. The module reads data in a size specified by the file itself, which means a maliciously crafted plist file can cause the program to consume excessive memory (Out Of Memory - OOM) and potentially lead to Denial of Service (DoS).

Impact Analysis

The impact of this vulnerability is that an attacker can supply a specially crafted plist file that causes the application using plistlib to consume excessive memory, potentially crashing the application or making it unavailable, resulting in a Denial of Service (DoS).
