- Summary
- Memory-amplification denial of service via declared-length preallocation in Amazon ion-java
- Details
-
Uncontrolled memory allocation in the binary Ion stream cursor in Amazon ion-java before 1.12.0 might allow remote actors to cause a denial of service via a crafted Ion binary document containing a declared-length field that causes excessive heap preallocation.
To remediate this issue, users should upgrade to version 1.12.0.
