Ion Java StackOverflow vulnerability

High
popematt published GHSA-264p-99wq-f4j6 Jan 3, 2024

Package

maven com.amazon.ion:ion-java (Maven)

Affected versions

< 1.10.5

Patched versions

>= 1.10.5

Description

Impact

A potential denial-of-service issue exists in ion-java for applications that use ion-java to:

  • Deserialize Ion text encoded data, or
  • Deserialize Ion text or binary encoded data into the IonValue model and then invoke certain IonValue methods on that in-memory representation.

An actor could craft Ion data that, when loaded by the affected application and/or processed using the IonValue model, results in a StackOverflowError originating from the ion-java library.

Impacted versions: <1.10.5

Patches

The patch is included in ion-java >= 1.10.5.

Workarounds

Do not load data which originated from an untrusted source or that could have been tampered with. Only load data you trust.

If you have any questions or comments about this advisory, we ask that you contact AWS/Amazon Security via our vulnerability reporting page [1] or directly via email to aws-security@amazon.com. Please do not create a public GitHub issue.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
