CBL Mariner 2.0 Security Update: python-cryptography (CVE-2023-49083)

high Nessus Plugin ID 201655

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of python-cryptography installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-49083 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.

Solution

Update the affected packages.
