| Package | Affected versions | Patched versions |
|---|---|---|
| opc ua tunneller | < 6.3.0.8233 | 6.3.0.8233 |
Some parsing functions in the affected product do not check the return value of malloc and the thread handling the message is forced to close, which may lead to a denial-of-service condition on the OPC UA Tunneller (versions prior to 6.3.0.8233).
