Cryptography vulnerable to buffer overflow if non-contiguous buffers were passed to APIs

If a non-contiguous buffer was passed to APIs which accepted Python buffers e.g. Hash.update, this could lead to buffer overflows. For example: python h = HashSHA256 b.updatebuf::-1 would read past the end of the buffer on Python 3.11...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write in the update function when non-contiguous buffers are provided as input. An attacker can cause memory corruption or unintended behavior by supplying specially crafted non-contiguous buffers to APIs that accept Pytho...
