Summary

Infinite loop condition in Amazon.IonDotnet

Details

Summary

Amazon.IonDotnet (ion-dotnet) is a .NET library with an implementation of the Ion data serialization format.

An issue exists in Amazon.IonDotnet and the RawBinaryReader class where, under certain conditions, an actor could trigger an infinite loop condition.

Impact

When reading binary Ion data through Amazon.IonDotnet using the RawBinaryReader class, Amazon.IonDotnet does not check the number of bytes read from the underlying stream while deserializing the binary format. If the Ion data is malformed or truncated, this triggers an infinite loop condition that could potentially result in a denial of service.

Impacted versions: <=1.3.0

Patches

This issue has been addressed in Amazon.IonDotnet version 1.3.1. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.

Workarounds

There are no workarounds. Upgrade to version 1.3.1.
