Type Confusion

Affected versions of this package are vulnerable to Type Confusion in the do_x509_check() function in x509/v3_utl.c, which is responsible for certificate name checks. An application that specifies an expected DNS name, Email address or IP address that performs a name check on an otherName subject alternative name of an X.509 certificate can be made to crash when it attempts to read an invalid memory address.

Note: Users that are building cryptography source ("sdist") are responsible for upgrading their copy of OpenSSL.

How to fix Type Confusion?

Upgrade cryptography to version 43.0.1 or higher.
