TOP VULNERABILITY THIS WEEK: A Metasploit module emerged this week for

a vulnerability silently patched by Microsoft in their July bulletin
set. While the vulnerability is restricted to Internet Explorer 8, the
publication of a simple exploit ensures that it will be used in the wild
immediately.

NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Microsoft releases huge pile of patches
Description: Microsoft’s monthly patch release this week contained a
whopping 47 CVEs, spread across 13 total bulletins. Only a single one
of the vulnerabilities was listed as having been previously disclosed,
with no note on in-the-wild exploitation on any of the bugs. The
patches, which run the gamut from privilege escalation to remote code
execution, are certain to present fertile ground for attackers going
forward, with exploits likely to emerge for at least some of the bugs
in the near future.

Title: Silently patched Internet Explorer 8 exploit now has Metasploit
module
Description: After being discovered by security researcher Orange Tsai
earlier this year, and discussed at Hitcon 2013, a bug in Internet
Explorer version 8 is gaining new life this week, with a fully
functional Metasploit module for the attack being made public. Though
the issue was silently patched in Microsoft bulletin MS13-055 this July,
the widespread availability of a working attack makes it considerably
more likely that exploitation will occur in the wild in the near future.

Title: Dropbox presents ASLR bypass for other programs when installed
Description: An independent security researcher this week made public a
surprising consequence of running the popular Dropbox file-sharing
software: doing so, at least on 32-bit systems, presents an ASLR-free
zone for exploiting other high-risk applications, such as web browsers
or file sharing clients. Specifically, Dropbox injects itself in DLL
form into open windows, and as such can be used by exploits targeting
the injected processes for code execution techniques that are typically
mitigated by ASLR. Mitigation includes using EMET to force ASLR on all
processes system-wide.
