OpenSSH < 4.2p1 GSSAPI Authentication Credential Escalation

Low Nessus Network Monitor Plugin ID 3205


The remote host is vulnerable to a flaw that allows attackers to retrieve sensitive files or data.


The remote host is running a version of OpenSSH which is vulnerable to a flaw in the way that it handles GSSAPI authentication. Specifically, if GSSAPI is enabled and 'GSSAPIDelegateCredentials' is enabled, an attacker may gain access to GSSAPI credentials.

Note: PVS has solely relied on the banner of the SSH client to perform this check. Any backported patches or workarounds such as recompiling or edited configurations are not observable through the banner.


Upgrade to version 4.2p1 or higher.
