Python PyOS_vsnprintf integer overflow

python-pyosvsnprintf-overflow (44171) The risk level is classified as HighHigh Risk

Description:

Python is vulnerable to multiple integer overflows in the PyOS_vsnprintf function. A remote attacker could exploit this vulnerability via specially-crafted input to string formatting operations to corrupt memory and execute arbitrary code on the system with elevated privileges or cause the application to crash.
