Summary

IBM DataPower Gateway versions 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, and 11.0.0.0 through 11.0.0.2 are affected. A heap buffer underwrite (CWE-124) lets a remote attacker write before the start of a heap buffer. An attacker can exploit this without authentication, which may crash the service.
