TencentOS Server 3: .NET 8.0 (TSSA-2024:0727)

critical Nessus Plugin ID 238536

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-2024:0727 advisory.

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

 CVE-2024-38229:
 A flaw was found in dotnet. When closing an HTTP/3 stream while application code is writing to the response body, a race condition can cause a use-after-free.

 CVE-2024-43483:
 A flaw was found in dotnet. The System.Security.Cryptography.Cose, System.IO.Packaging and System.Runtime.Caching components may be exposed to hostile input, making them susceptible to hash flooding attacks, resulting in denial of service.

 CVE-2024-43484:
 .NET, .NET Framework, and Visual Studio Denial of Service Vulnerability

 CVE-2024-43485:
 .NET and Visual Studio Denial of Service Vulnerability

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.
