This at least causes the program to segmentation abort if the heap size parameter isn’t aligned correctly. In version before GLIBC version 2.29 and aligned correctly, it allows arbitrary write anywhere in the programs memory.

CVE-2020-10735

Read Time:21 Second

A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when using int(“text”), a system could take 50ms to parse an int string with 100,000 digits and 5s for 1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not affected). The highest threat from this vulnerability is to system availability.
