high Nessus Plugin ID 239367

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-2024:0240 advisory.

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

CVE-2024-4367:
A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes this flaw as follows: A type check was missing when handling fonts in PDF.js, which would allow arbitrary JavaScript execution in the PDF.js context.

CVE-2024-4767:
A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes this flaw as follows: If the `browser.privatebrowsing.autostart` preference is enabled, IndexedDB files were not properly deleted when the window was closed. This preference is disabled by default in Firefox.

CVE-2024-4768:
A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes this flaw as follows: A bug in popup notifications' interaction with WebAuthn made it easier for an attacker to trick a user into granting permissions.

CVE-2024-4769:
A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes this flaw as follows: When importing resources using Web Workers, error messages would distinguish the difference between `application/javascript` responses and non-script responses. This could have been abused to learn information cross-origin.

CVE-2024-4770:
A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes this flaw as follows: When saving a page to PDF, certain font styles could have led to a potential use-after-free crash.

CVE-2024-4777:
A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes this flaw as follows:
Memory safety bugs present in Firefox 125, Firefox ESR 115.10, and Thunderbird 115.10. 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.

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.
