high Nessus Plugin ID 189201


The remote Oracle Linux host is missing a security update.


The remote Oracle Linux 8 / 9 host has a package installed that is affected by a vulnerability as referenced in the ELSA-2024-12079 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Update the affected python3-cryptography package.
