HOW TO FIX?

A fix was pushed into the master branch but not yet published.


OVERVIEW

Affected versions of this package are vulnerable to Allocation of Resources
Without Limits or Throttling via the deserialization of Ion text encoded data or
the IonValue model processing. An attacker can cause a StackOverflowError by
crafting malicious Ion data that triggers excessive resource consumption when
loaded or processed. This is only exploitable if the application deserializes
Ion data from an untrusted source or data that could have been tampered with.

Notes:

According to the README.md file of this package, its domain changed from
software.amazon.ion to com.amazon.ion. Please be aware that this vulnerability
affects versions of both domains of this package.

For a fix, please check the advisory on the maintained package.


WORKAROUND

This vulnerability can be mitigated by not loading data from untrusted sources
or that could have been tampered with.
