    A denial-of-service vulnerability exists in Sysax Multi-Server version 6.10 via its SSH daemon. A specially crafted SSH key exchange packet can trigger a crash in the service, resulting in loss of availability. The flaw is triggered during the handling of malformed key exchange data, including a non-standard byte (\x28) in place of the expected SSH protocol delimiter.
