TOP VULNERABILITY THIS WEEK: Multiple remotely exploitable 0-day attacks

were released against MySQL this weekend, with proof of concept
available for each issue. The bugs, which range from buffer overflows
to user enumeration, are being actively exploited in the wild now, and
no patches are available.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Multiple Remote 0-Day Attacks Against MySQL Databases
Description: A slew of remotely exploitable bugs in MySQL were released
by security researcher KingCope on the Full-Disclosure mailing list over
the weekend, with exploits including buffer overflows, user enumeration
techniques, and denial-of-service attacks. As no patches are currently
available, some of the issues target default configurations, and
exploits are already circulating in the wild, system administrators are
urged to lock down access to their database systems to only authorized
users wherever possible as a mitigation until patches become available.

Title: Dump of Syrian Ministry of Foreign Affairs’ Email Reveals Targeted Malware
Description: After Anonymous published a dump of email from the Syrian
Ministry of Foreign Affairs on the site “Par:AnoIA”, researchers noted
that a message sent on December 5, 2011 contained targeted malware,
which entered the system via a PDF exploit using CVE-2010-0188. A
similar attack has been used in targeted campaigns over the course of
the last year, according to Kaspersky.

Title: Windows AutoRun Malware Makes A Comeback
Description: Several security vendors have noted recently that malware
known alternately as W32/Autorun or W32/Changeup - which spreads via the
AutoRun feature on Windows when removable media is plugged into a system

dormant this year. System administrators should disable the AutoRun
feature wherever feasible, in addition to deploying AV and IDS
signatures as appropriate.

Title: Exploit Kit Market Continues To Expand
Description: New exploit kits are continuing to emerge in the wild, as
that model of online criminal economics becomes more dominant by the
day. Kits such as Sweet Orange and the Cool Exploit Kit, released within
the last few months, are nowhere near as dominant as established players
like Blackhole or Phoenix, but are equally dangerous, and network
defenders need to be paying attention to them as well as the heavy
hitters of the industry.
