I’m no geography expert, but I didn’t think there were beaches in Atlanta. After reading Dan Holden’s post on ISS’ “Frequency X” blog, I am beginning to doubt this presumed truth. There MUST be beaches in Atlanta… I don’t see any other way that Holden and ISS could have their heads so deep in the sand.
November has been informally designated the “Month of Kernel Bugs” in security circles. The Month of Kernel Bugs began on November 1, with the publication of a vulnerability in Apple’s AirPort drivers. SecuriTeam blogs did an interview with LMH, who hosts the Month of Kernel Bugs project (aka MoKB); the text of our interview is below (after the jump).
Sunbelt’s recent Vector Markup Language (VML) vulnerability discovery has drawn some attention here on the blogs, and rightly so. The impact of the vulnerability is fairly significant and there are reports that malicious sites are exploiting the vulnerability to install malicious code of all sorts.
For those without perimeter/endpoint defenses to identify the exploit and those seeking additional assurances that the issue can be effectively blocked, I’d like to note some workarounds that I’ve found effective. The vulnerable component in this instance is vgx.dll. Microsoft has proposed three workarounds in Security Advisory 925568 that appear to be effective in blocking the attack, and another aimed at mitigating the attack.
Microsoft notes that reading e-mail in plain text is a mitigator against e-mail based attacks, but the attacks seen at this time are not e-mail based, to the best of my knowledge. You may disable access to vgx.dll by either un-registering it or blocking access with file system access control lists. Microsoft also suggests users of Windows XP SP2 disable binary and script behaviors within Internet Explorer. All of these workarounds are effective, and you should apply them if possible.
Some important guidance, however, is absent from the Microsoft advisory, and I’d like to raise it here.
While it still appears that few have been affected by attacks targeting the newly-reported Microsoft Word vulnerability, I’ve provided a registry script that can be deployed on Windows XP to eliminate the impact of the current malware targeting the vulnerability.
