TOP VULNERABILITY THIS WEEK: A new zero-day attack for Adobe Acrobat

Reader X has been discovered, according to Russian firm Group-IB. While
attacks to date appear to be limited, due to the need for user
interaction before exploitation can take place, it can be assumed that
underground researchers are working on a mechanism to automate the
exploit, so that it can be used in drive-by downloads and exploit kits.

NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Adobe Flash 0-Day
Description: A new Adobe Acrobat Reader X memory corruption
vulnerability was recently announced by Group-IB, a Russian
cybersecurity firm. While initial reports were that it was to be added
to the Blackhole Exploit Kit immediately, researchers soon noted that
exploiting the bug required manual user interaction - specifically, the
malicious file would have to be closed like a normal document - which
would make it unsuitable for Blackhole and other automated exploitation
systems. Exploits have been limited in the wild thus far, but given the
difficulty of bypassing Adobe’s recently added sandboxing and other
security features, cybercriminals are likely working on ways to automate
exploitation already. As no patch currently exists, potentially
vulnerable users should exercise caution when opening potentially
suspicious PDF documents.

Title: 64-bit Linux Rootkit Uses Novel Techniques
Description: A new type of 64-bit Linux rootkit was discovered in the
wild last week, after an infected user posted details from an infected
server on the Full-Disclosure mailing list. The rootkit was found
injecting malicious iframes into all HTTP responses served up by the
victim’s nginx web server, a popular open-source, lightweight system
programmed by Russian-based company Nginx, Inc. This technique, which
can easily be used to assist in drive-by downloads and other exploit kit
style behavior, is a fascinating new twist on cybercriminals’ efforts
to continue infecting large swaths of the public for use in worldwide
botnets.

Title: Novell File Reporter 0-Day Exploits Available in Metasploit
Description: Multiple remote file retrieval vulnerabilities plus a
remote code execution bug were announced last week in Novell’s File
Reporter software, used for coordinating data storage across multiple
filesystems and/or storage solutions. The vulnerabilities have already
been added to Metasploit, and as no patch currently exists, exploits are
presumed to be occurring in the wild. Potentially impacted customers are
urged to firewall off their devices appropriately until a patch is
released.

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-2012-4956
Title: Novell File Reporter Vulnerabilities
Vendor: Novell
Description: Heap-based buffer overflow in NFRAgent.exe in Novell File
Reporter 1.0.2 allows remote attackers to execute arbitrary code via a
large number of VOL elements in an SRS record.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: : CVE-2012-2897
Title: Microsoft Windows Kernel TrueType Font Integer Underflow Vulnerability
Vendor: Microsoft
Description: The kernel-mode drivers in Microsoft Windows XP SP2 and
