Description

By overlong input values an attacker may force overwrite of the internal program stack in SAP Web Dispatcher - versions 7.53, 7.77, 7.81, 7.85, 7.86, or Internet Communication Manager - versions KRNL64NUC 7.22, 7.22EXT, 7.49, KRNL64UC 7.22, 7.22EXT, 7.49, 7.53, KERNEL 7.22, 7.49, 7.53, 7.77, 7.81, 7.85, 7.86, which makes these programs unavailable, leading to denial of service.
