Severity: important

Affected versions:

- Apache Johnzon through 1.2.20

Description:

Deserialization of Untrusted Data vulnerability in Apache Software Foundation 
Apache Johnzon.


A malicious attacker can craft up some JSON input that uses large numbers 
(numbers such asĀ 1e20000000) that Apache Johnzon will deserialize into 
BigDecimal and maybe use numbers too large which may result in a slow 
conversion (Denial of service risk). Apache Johnzon 1.2.21 mitigates this by 
setting a scale limit of 1000 (by default) to the BigDecimal. 


This issue affects Apache Johnzon: through 1.2.20.

This issue is being tracked as JOHNZON-397
