EulerOS Virtualization 2.11.1 : python-cryptography (EulerOS-SA-2024-1419)

high Nessus Plugin ID 192354

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the versions of the python-cryptography package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python-cryptography packages.
