MOST POPULAR MALWARE FILES 5/29/2012 - 6/5/2012

Top Vulnerability this week: The XML zero day that affects Internet
Explorer users as well as Office 2003 and 2007 users. It was important
enough for Microsoft to make an extra out-of-cycle patch available. The
reason it is so important is that most targeted attacks going after
sensitive intellectual property use a vector like the one used in this
attack.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: MySQL Authentication Brute Force Attack
Description: A trivially exploitable attack exists for certain platforms
running MySQL that allows attackers root access to the database without
any credentials. HD Moore has demonstrated a single-line shell script
that will grant access, so live attacks are presumed to exist in the
wild already, with automated scanners for this vulnerability likely to
follow (if not already available).

Title: Web Shell With GIF Header
Description: A live shell has been observed in the wild as part of
automated attempts to exploit the WordPress TimThumb vulnerability
released in August of 2011. This shell has a validly formed GIF header
prepended to the malicious PHP code, so that TimThumb’s built-in file
safety checks will be bypassed (as well as any other check based on
file(1), which declares the shell to be a valid GIF file). Several
monitoring organizations have reported this shell being dropped very
widely in the field.

Title: CVE-2012-1875 Microsoft Internet Explorer DOM manipulation memory corruption
Description: This is a complex Document Object Model heap overwrite, but
several actors are using it in targeted attacks observed across the
globe. Several variants of the attack are in public already, and more
are being traded in the underground. Users of Internet Explorer should
patch this bug as promptly as possible.

Snort SID: 23125
ClamAV: Exploit.CVE_2012_1875, Exploit.CVE_2012_1875-1

Title: Unauthorized Microsoft Security Certificates Allow Windows Update Spoofing
Description: The recently discovered Flame malware used a specifically
crafted SSL certificate to man-in-the-middle the Windows Update process
and inject code. As any certificate issued by a pair of intermediate
signing authorities could, if used by Flame or others, lead to
unauthorized content being trusted by the operating system, Microsoft
explicitly revoked all certificates issued by those authorities.

Title: CVE-2011-2140 Adobe Flash Player MP4 Buffer Overflow:
Description: A simple buffer overflow attack exists in the way Adobe
Flash parses certain chunks of MP4 files. Public exploits exist, and
have been incorporated into the Chinese Yang Pack exploit kit. Active
exploitation of this vulnerability has been observed in the wild by the
Sourcefire VRT.
