NVD Description

Note: Versions mentioned in the description apply only to the upstream libssh package and not the libssh package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

A flaw was found in libssh. When ProxyCommand is used, an unchecked fork() failure can be stored as process ID -1; during cleanup, signals may then be sent across the caller's accessible process tree, leading to local denial of service.
