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-2024:0814 advisory.

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

    CVE-2023-6681:
    A vulnerability was found in JWCrypto. This flaw allows an attacker to cause a denial of service (DoS)     attack and possible password brute-force and dictionary attacks to be more resource-intensive. This issue     can result in a large amount of computational consumption, causing a denial of service attack.

    CVE-2024-28102:
    JWCrypto implements JWK, JWS, and JWE specifications using python-cryptography. Prior to version 1.5.6, an     attacker can cause a denial of service attack by passing in a malicious JWE Token with a high compression     ratio. When the server processes this token, it will consume a lot of memory and processing time. Version     1.5.6 fixes this vulnerability by limiting the maximum token length.
