Date Reported: 12/9/97
Vulnerability: SNMP-config
Platforms Affected: Check Point FireWall-1
Risk Factor: Low
The default configuration of Check Point Firewall-1 may allow remote users
to access SNMP MIB information. The firewall can not be compromised
through this configuration; however, users should evaluate restricting the
availability of SNMP MIB information on all SNMP enabled devices.. For
additional information and a patch go to Check Point's public Web site at
http://www.checkpoint.com/techsupport/snmp/cp-fw-301-0024.html If a
customer has not upgraded to FireWall-1 3.0, a description of how to
change the configuration setting without the patch may be found at
http://www.checkpoint.com/techsupport/snmp/config/snmpindex.html

___
Date Reported: 12/6/97
Vulnerability: Slack-crond
Platforms Affected: Linux Slackware 3.4
Risk Factor: High
A vulnerability exists in Linux Slackware version 3.4's crond. A locally
exploitable buffer overflow condition that will allow local users with an
account to execute arbitrary code. By exploiting this vulnerability,
users can obtain root access.

___
Date Reported: 12/5/97
Vulnerability: statd
Platforms Affected: AIX (3.2, 4.1)
Digital UNIX (V4.0 - V4.0c)
Solaris (2.4, 2.5, 2.5.1)
SunOS (4.1.3, 4.1.4)
Risk Factor: High
statd provides network status monitoring and provides crash and recovery
functions for the locking services on NFS. Local users can exploit a
vulnerability in statd that would allow them to execute commands as the
user running statd, which is, in most cases, root. Remote users without
an account on the system would also be able to exploit this vulnerability
if statd is accessible on the network.

allows users to exploit the at command to gain root access.

Incident: Yahoo! Web Site Hacked
The Yahoo! web directory and search engine was hacked. Intruders changed
the web pages that are seen by Lynx and older Netscape browsers. Their
message was that they had planted a virus on Yahoo! and that anyone who
had viewed their pages had it. They also made statements that Kevin
Mitnick had been framed, and that they would only release the antidote to
their virus, if he was freed.

Risk Factor Key:
High any vulnerability that provides an attacker with immediate
access into a machine, gains superuser access, or bypasses
a firewall. Example: A vulnerable Sendmail 8.6.5 version
that allows an intruder to execute commands on mail
server.
Medium any vulnerability that provides information that has a
high potential of giving access to an intruder. Example:
A misconfigured TFTP or vulnerable NIS server that allows
an intruder to get the password file that possibly can
contain an account with a guessable password.
Low any vulnerability that provides information that
potentially could lead to a compromise. Example: A
finger that allows an intruder to find out who is online
and potential accounts to attempt to crack passwords
via bruteforce.
