Synopsis

The remote TencentOS Server 3 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2024:0204 advisory.

Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

CVE-2023-49083:
A null-pointer dereference vulnerability was found in python-cryptography during the loading of PKCS7 certificates. Invoking load_pem_pkcs7_certificates or load_der_pkcs7_certificates can trigger this issue and lead to subsequent segmentation fault and result in a Denial of Service (DoS) for any application aiming to deserialize a PKCS7 blob or certificate. The potential impact includes disruptions in system availability and stability.

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

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.
