high Nessus Plugin ID 238672

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-2024:0117 advisory.

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

CVE-2023-50269:
A flaw was found in Squid, which is susceptible to a Denial of Service (DoS) due to an Uncontrolled Recursion bug, specifically targeting HTTP Request parsing. Exploiting this issue involves a remote client initiating a DoS attack by sending an oversized X-Forwarded-For header when the follow_x_forwarded_for feature is configured. This issue poses a threat to the stability and availability of the Squid service.

CVE-2024-25111:
A flaw was found in Squid. This issue may allow a remote attacker to trigger an uncontrolled recursion bug when sending a specially crafted, chunked, encoded HTTP Message, resulting in a denial of service.

CVE-2024-25617:
A flaw was found in Squid. This issue may allow a remote client or remote server to trigger a denial of service when sending oversized headers in HTTP messages.

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.
