## How to fix

- Fixed in 0.25.0

## Technical details

The Apache Thrift Ruby bindings fail to properly handle exceptional conditions, resulting in uncaught exceptions that can be triggered by network input or malformed data. An attacker with network access to a service using the affected Ruby bindings can exploit this improper exception handling to crash the application. The issue is resolved in version 0.25.0.

## Affected products

- Apache Thrift before 0.25.0
