high Nessus Plugin ID 238541
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-2024:0388 advisory.Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:
CVE-2024-25126:
Rack is a modular Ruby web server interface. Carefully crafted content type headers can cause Racks media type parser to take much longer than expected, leading to a possible denial of service vulnerability (ReDos 2nd degree polynomial). This vulnerability is patched in 3.0.9.1 and 2.2.8.1.
CVE-2024-26141:
Rack is a modular Ruby web server interface. Carefully crafted Range headers can cause a server to respond with an unexpectedly large response. Responding with such large responses could lead to a denial of service issue. Vulnerable applications will use the Rack::File middleware or the Rack::Utils.byte_ranges methods (this includes Rails applications). The vulnerability is fixed in 3.0.9.1 and 2.2.8.1.
CVE-2024-26146:
Rack is a modular Ruby web server interface. Carefully crafted headers can cause header parsing in Rack to take longer than expected resulting in a possible denial of service issue. Accept and Forwarded headers are impacted. Ruby 3.2 has mitigations for this problem, so Rack applications using Ruby 3.2 or newer are unaffected. This vulnerability is fixed in 2.0.9.4, 2.1.4.4, 2.2.8.1, and 3.0.9.1.
Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.
