NVD Description

Note: Versions mentioned in the description apply only to the upstream python-cryptography package and not the python-cryptography package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

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.
