Doc Text:
A vulnerability was found in the Python core plistlib library within the read_ints() function in the plistlib.py file. In malformed input, the implementation can be manipulated to create an argument for struct.unpack(). This issue can lead to excessive CPU and memory consumption, resulting in a MemError, as it constructs the 'format' argument for unpack(). This flaw allows an attacker to employ a binary plist input, potentially executing a denial of service (DoS) attack by exhausting CPU and RAM resources.
