Test ID:	1.3.6.1.4.1.25623.1.0.10517
Category:	Gain root remotely
Title:	pam_smb / pam_ntdom overflow
Summary:	NOSUMMARY
Description:	Description: The remote telnet server shut the connection abruptly when given a long username followed by a password. Although Nessus could not be 100% positive, it may mean that the remote host is using an older pam_smb or pam_ntdom pluggable authentication module to validate user credentials against a NT domain. Older version of these modules have a well known buffer overflow which may allow an intruder to execute arbitrary commands as root on this host. It may also mean that this telnet server is weak and crashes when issued a too long username, in this case this host is vulnerable to a similar flow. This may also be a false positive. Solution : . if pam_smb or pam_ntdom is being used on this host, be sure to upgrade it to the newest non-devel version. . if the remote telnet server crashed, contact your vendor for a patch Risk factor : High
