python3-cryptography: fix CVE-2023-49083

Browse Source 
cryptography is a package designed to expose cryptographic primitives
and recipes to Python developers. Calling `load_pem_pkcs7_certificates`
or `load_der_pkcs7_certificates` could lead to a NULL-pointer dereference
and segfault. Exploitation of this vulnerability poses a serious risk of
Denial of Service (DoS) for any application attempting to deserialize a
PKCS7 blob/certificate. The consequences extend to potential disruptions
in system availability and stability. This vulnerability has been patched
in version 41.0.6.
