USN-8087-1 fixed a vulnerability in python-cryptography. The update caused a regression when using ECC algorithms with certain software. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was discovered that python-cryptography incorrectly handled subgroup validation for SECT curves. A remote attacker could use this issue to perform a subgroup attack and possibly recover the least significant bits of private keys.
