SSH: Multiple SSH2 Clients and Servers Buffer Overflow Denial of Service

This signature detects attempts to exploit a known vulnerability against multiple SSH2 servers and clients. A successful attack can result in a denial-of-service condition.

Extended Description

Multiple SSH2 servers and clients do not properly handle large packets or large fields, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code via buffer overflow attacks, as demonstrated by the SSHredder SSH protocol test suite.
