TencentOS Server 4: openvpn (TSSA-2025:0091)

high Nessus Plugin ID 239514

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 multiple vulnerabilities as referenced in the TSSA-2025:0091 advisory.

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

CVE-2024-5594:
OpenVPN before 2.6.11 does not santize PUSH_REPLY messages properly which attackers can use to inject unexpected arbitrary data into third-party executables or plug-ins.

CVE-2024-28882:
OpenVPN from 2.6.0 through 2.6.10 in a server role accepts multiple exit notifications from authenticated clients which will extend the validity of a closing session

CVE-2024-27459:
The interactive service in OpenVPN 2.6.9 and earlier allows an attacker to send data causing a stack overflow which can be used to execute arbitrary code with more privileges.

CVE-2024-24974:
The interactive service in OpenVPN 2.6.9 and earlier allows the OpenVPN service pipe to be accessed remotely, which allows a remote attacker to interact with the privileged OpenVPN interactive service.

Tenable has extracted the preceding description block directly from the Tencent 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 packages.
