Synopsis

The remote CentOS host is missing a security update.

Description

The remote CentOS Linux 8 host has a package installed that is affected by a vulnerability as referenced in the CESA-2024:3105 advisory.

 - 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. (CVE-2023-49083)
