TencentOS Server 4: python-asyncssh (TSSA-2024:1054)

high Nessus Plugin ID 239507

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-2024:1054 advisory.

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

CVE-2023-46445:
An issue in AsyncSSH before 2.14.1 allows attackers to control the extension info message (RFC 8308) via a man-in-the-middle attack, aka a Rogue Extension Negotiation.

CVE-2023-46446:
An issue in AsyncSSH before 2.14.1 allows attackers to control the remote end of an SSH client session via packet injection/removal and shell emulation, aka a Rogue Session Attack.

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.
