TencentOS Server 4: ceph (TSSA-2026:0534)

medium Nessus Plugin ID 325855

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:0534 advisory.

 Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

 CVE-2024-31884:
 A flaw was found in Ceph. An attacker can allow Ceph to accept any certificate because no certificate context is passed via Pybind to the constructors imaplib.IMAP4_SSL or smtplib.SMTP_SSL. As a result, pybind pybind does not check the server's X.509 certificate, instead accepting any certificate. This enables an attacker to commit a Man In the Middle (MITM) attack, compromising mail server credentials or mail contents

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.
