cpython: Out-of-memory when loading Plist

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...

The 'zipfile' module would not check the validity of the ZIP64 End of Central Directory EOCD Locator record offset value would not be used to locate the ZIP64 EOCD record, instead the ZIP64 EOCD record wou...

cpython: Excessive read buffering DoS in http.client

A flaw was found in the http.client module in the Python standard library. When reading an HTTP response from a server, if no read amount is specified, the default behavior will be to use Content-Length. This issue allows a malicious server to cause the client to read large amounts of data into...
