DoS Exploit for MS-053
Incidents.org has the story on an “in the wild” exploit for MS-053 vulnerability. The patch is out, so if you haven’t already – go ahead with the patching. The vulnerability is entitled “Vulnerabilities in Graphics Rendering Engine Could Allow Code Execution (896424)”. The exploit causes 100% cpu utilitzation on visiting a page with a specially crafted file using Internet Explorer. The “attacking” page could essentially cause a system freeze.
Remember though, the javascript (unpatched) vulnerability of last week was ORIGINALLY marked at a DoS only vuln, last week it was discovered that Remote Code Execution was possible. So, any remote vulnerability should be treated with urgency in patching.
