CVE-2006-5051 is a signal-handler race condition in OpenSSH versions before 4.4. Excessive functionality in a signal handler creates a race condition that can lead to a double-free condition. Remote attackers can crash the affected OpenSSH service. When GSSAPI authentication is enabled, the double-free may also permit arbitrary code execution; the precise vectors leading to the double free are unspecified.
