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-2024:0429 advisory.

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

    CVE-2024-23672:
    Denial of Service via incomplete cleanup vulnerability in Apache Tomcat.

    Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M10, from     10.1.0-M1 through 10.1.15, from 9.0.0-M1 through 9.0.82 and from 8.5.0 through 8.5.95 did not correctly     parse HTTP trailer headers. A trailer header that exceeded the header size limit could cause Tomcat to     treat a single     request as multiple requests leading to the possibility of request     smuggling when behind a reverse proxy.

    Users are recommended to upgrade to version 11.0.0-M11onwards, 10.1.16 onwards, 9.0.83 onwards or 8.5.96     onwards, which fix the issue.
