CVE-2021-40647

September 9, 2022

Read Time:18 Second

In man2html 1.6g, a specific string being read in from a file will overwrite the size parameter in the top chunk of the heap. 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

September 9, 2022

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.
