Oracle Linux 8 : .NET / Core / 3.1 (ELSA-2022-0827)

medium Nessus Plugin ID 158884

Synopsis

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

Description

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-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 this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
