Doc Text:
A flaw was found in the plistlib module in the Python standard library. The amount of data to read from a Plist file is specified in the file itself. This issue allows a specially crafted Plist file to cause an application to allocate a large amount of memory, potentially resulting in allocations errors, swapping, out-of-memory conditions or even system freezes.
