Rocky Linux 8 : .NET Core 3.1 (RLSA-2022:0827)

medium Nessus Plugin ID 184566

Synopsis

The remote Rocky Linux host is missing one or more security updates.

Description

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2022:0827 advisory.

- A buffer overflow exists in the Brotli library versions prior to 1.0.8 where an attacker controlling the input length of a one-shot decompression request to a script can trigger a crash, which happens when copying over chunks of data larger than 2 GiB. It is recommended to update your Brotli library to 1.0.8 or later. If one cannot update, we recommend to use the streaming API as opposed to the one-shot API, and impose chunk size limits. (CVE-2020-8927)

- .NET and Visual Studio Denial of Service Vulnerability (CVE-2022-24464)

- .NET and Visual Studio Remote Code Execution Vulnerability (CVE-2022-24512)

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.
