Summary
IBM DataPower Gateway 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 sorting comparator violates strict weak ordering, which causes out-of-bounds memory access (CWE-787). A remote attacker without privileges or user interaction can cause a denial of service.
