Stop using pycrypto. Use pycryptodome instead
As we are still seeing a lot of applications depending on the Python Cryptography Toolkit (aka pycrypto) to manage their cryptography, this is a quick reminder to stop using it.
Pycrypto is vulnerable to a heap-based buffer overflow in the ALGnew function in block_templace.c. It allows remote attackers to execute arbitrary code in the python application. It was assigned the CVE-2013-7459 number.
Pycrypto didn’t release any fix to that vulnerability and no commit was made to the project since Jun 20, 2014.
Pycryptodome to the rescue
Pycryptodome is a drop-in replacement for the PyCrypto library. Just ‘pip install pycryptodome’ and you’re good to go.
