Alibaba Cloud Linux 3 : 0274: python3.11-cryptography (ALINUX3-SA-2024:0274)

critical Nessus Plugin ID 236156

Synopsis

The remote Alibaba Cloud Linux host is missing one or more security updates.

Description

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2024:0274 advisory.

 Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

 CVE-2023-23931:
 cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In affected versions `Cipher.update_into` would accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable objects (such as `bytes`) to be mutated, thus violating fundamental rules of Python and resulting in corrupted output. This now correctly raises an exception. This issue has been present since `update_into` was originally introduced in cryptography 1.8.

 CVE-2023-49083:
 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.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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

Solution

Update the affected python3.11-cryptography, python3.11-cryptography-debuginfo and / or python3.11-cryptography- debugsource packages.
