CVE-2022-48564

read_ints in plistlib.py in Python through 3.9.1 is vulnerable to a potential DoS attack via CPU and RAM exhaustion when processing malformed Apple Property List files in binary format.

Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems.

Security Fix(es):

• python: use after free in heappushpop() of heapq module (CVE-2022-48560)
• python: DoS when processing malformed Apple Property List files in binary format (CVE-2022-48564)
