The remote NewStart CGSL host, running version MAIN 6.06, has python-cryptography packages installed that are affected by multiple vulnerabilities: - In Python before 3,9,5, the ipaddress library mishandles leading zero characters in the octets of an IP address string. This in some situations...

python-cryptography: memory corruption via immutable objects

A vulnerability was found in python-cryptography. In affected versions, Cipher.updateinto would accept Python objects which implement the buffer protocol but provide only immutable buffers. This issue allows immutable objects such as bytes to be mutated, thus violating the fundamental rules of...

Enough Polynomials and Linear Algebra to Implement Kyber

I was once talking with a mathematician and trying to explain elliptic curve cryptography. Eventually, something clicked and they went "oh, that! I think there was a chapter about it in the book. You made a whole field out of it?" Yes, in cryptography we end up focusing on a very narrow slice of...
