TOP VULNERABILITY THIS WEEK: SCADA security continues to be a hot-button

issue, with a pair of vendors claiming a massive cache of 0-day remote
code execution bugs in a variety of product suites. Details are sketchy
at best for the time being, but users of potentially impacted software
are urged to work with ICS-CERT and their vendor(s) to resolve the
problems as soon as information about these exploits surfaces.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Multiple SCADA 0-Day Remote Exploits
Description: Responding to claims by Maltese security firm ReVuln that
it had discovered multiple remotely exploitable bugs in different SCADA
systems, but would not be supplying details of the bugs to impacted
vendors, reverse-engineering firm Exodus Intel has provided details of
23 distinct SCADA vulnerabilities - including a number of remote code
execution bugs - to ICS-CERT, the US government organization
specifically in charge of SCADA security. While no details of either set
of vulnerabilities has been released to date, users of potentially
impacted software are urged to contact ICS-CERT for mitigation
information as soon as possible, and to work with their vendors to patch
promptly once updates become available.

Title: Samsung Printer Backdoor Account
Description: Network-aware printers manufactured by Samsung before
October 31, 2012 (including some Dell printers actually built by
Samsung) have a hard-coded SNMP read-write community string, which
enables full administrative access to the device - even when SNMP has
been disabled by the user. A patch is currently being developed by
Samsung; in the interim, users should consider blocking all SNMP traffic
to impacted printers, which likely contain sensitive information that
could be used by an attacker or industrial spy.

Title: Invision IP Board Remote Code Execution
Description: A problem handling PHP serialized code in certain cookie
values leads to trivial remote code execution in the Invision IP Board
system, a popular web forum. Exploits have been released in Metasploit
and elsewhere, and attacks are presumed to be occurring in the wild.
Impacted users should patch their systems immediately.

Title: Lighttpd Web Server Denial of Service
Description: A trivially exploitable denial-of-service attack was
recently discovered in the popular Lighttpd web server, known for its
small footprint and ease of deployment on resource-constrained systems.
Users with simple HTTP request creation tools can easily exploit this
vulnerability to take sites offline. Impacted users are urged to patch
immediately.

RECENT VULNERABILITIES FOR WHICH EXPLOITS ARE AVAILABLE COMPILED BY THE QUALYS VULNERABILITY RESEARCH TEAM

This is a list of recent vulnerabilities for which exploits are
available. System administrators can use this list to help in
prioritization of their remediation activities. The Qualys Vulnerability
Research Team compiles this information based on various exploit
frameworks, exploit databases, exploit kits and monitoring of internet
activity.

ID: : CVE-2012-3752
Title: Apple QuickTime 7.7.2 TeXML Style Element font-table Field Stack
Buffer Overflow
Vendor: Apple
Description: Multiple buffer overflows in Apple QuickTime before 7.7.3
allow remote attackers to execute arbitrary code or cause a denial of
service (application crash) via a crafted style element in a QuickTime
