OpenBSD Portable OpenSSH < 4.4.p1 GSSAPI Authentication Overflow

High

Synopsis

The remote host is vulnerable to a buffer overflow.

Description

The remote host is running a version of OpenSSH that is vulnerable to a flaw in the way that it handles GSSAPI authentication. If the SSH server is configured to utilize GSSAPI authentication then the host may be compromised by a remote attacker with access to the SSH port (typically 22). Successful exploitation would result in remote code execution.

Solution

Upgrade to version 4.4.p1 or higher.
