SCA: security update for ParquetSharp (GHSA-rrjr-v56m-ww88)

medium Tenable Self-Hosted Container Security Plugin ID 440800

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - ParquetSharp is a .NET library for reading and writing Apache Parquet files. From version 18.1.0 to before
 version 23.0.0.1, DecimalConverter.ReadDecimal makes a stackalloc using what might be an attacker-supplied
 value. If an attacker declares a decimal column with some unreasonable width, this could lead to a stack
 overflow. In a service environment, this would potentially take down a service. This affects applications
 using ParquetSharp to read untrusted Parquet files in a network service. This issue has been patched in
 version 23.0.0.1. (CVE-2026-42241)

Solution

Update the ParquetSharp library and its related packages to version 23.0.0.1 or later.
