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 multiple vulnerabilities as referenced in the TSSA-2023:0173 advisory.

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

CVE-2023-2602:
A vulnerability was found in the pthread_create() function in libcap. This issue may allow a malicious actor to use cause __real_pthread_create() to return an error, which can exhaust the process memory.

CVE-2023-2603:
