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-2025:0417 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities: CVE-2025-5268: Memory safety bugs present in Firefox 138, Thunderbird 138, Firefox ESR 128.10, and Thunderbird 128.10. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 139 and Firefox ESR < 128.11. CVE-2025-5267: A clickjacking vulnerability could have been used to trick a user into leaking saved payment card details to a malicious page. This vulnerability affects Firefox < 139 and Firefox ESR < 128.11. CVE-2025-5266: Script elements loading cross-origin resources generated load and error events which leaked information enabling XS-Leaks attacks. This vulnerability affects Firefox < 139 and Firefox ESR < 128.11. CVE-2025-5264: Due to insufficient escaping of the newline character in the Copy as cURL feature, an attacker could trick a user into using this command, potentially leading to local code execution on the user's system. This vulnerability affects Firefox < 139, Firefox ESR < 115.24, and Firefox ESR < 128.11. CVE-2025-5263: Error handling for script execution was incorrectly isolated from web content, which could have allowed cross-origin leak attacks. This vulnerability affects Firefox < 139, Firefox ESR < 115.24, and Firefox ESR < 128.11. 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.
