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-2026:1049 advisory.

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

CVE-2026-91105:
A flaw was found in HPLIP.

CVE-2026-91103:
A flaw was found in HPLIP (HP Linux Imaging and Printing) software. This issue encompasses multiple vulnerabilities across several components, potentially allowing an attacker to achieve remote code execution, elevate their privileges, or cause a denial of service. Additionally, these flaws could lead to information disclosure or unauthorized file modification under certain conditions.

CVE-2026-91098:
A flaw was found in HP Linux Imaging and Printing (HPLIP) software. Multiple vulnerabilities exist that could allow a remote attacker to achieve remote code execution, escalate privileges, cause a denial of service, disclose information, or modify files without authorization under certain conditions.

CVE-2026-91097:
