Freebsd · Openam · CVE-2006-0883
**Name of the Vulnerable Software and Affected Versions**
OpenSSH on FreeBSD versions 5.3 through 5.4
**Description**
The issue arises when OpenSSH on FreeBSD is used with OpenPAM and a forked child process terminates during PAM authentication. This allows remote attackers to cause a denial of service by connecting multiple times to the SSH server, waiting for the password prompt, and then disconnecting.
**Recommendations**
For OpenSSH on FreeBSD versions 5.3 through 5.4, consider restricting access to the SSH server or implementing measures to limit the number of concurrent connections as a temporary workaround until a patch is available.
