New exploits emerge in wake of Patch Tuesday

Posted by   Virus Bulletin on   Apr 13, 2007

Security update release cycle leads to attack release cycle.

With the monthly 'Patch Tuesday' issue of security updates over, the now customary revelations of further vulnerabilities has begun, with attackers giving their creations as much time as possible to take effect before any fix is likely.

After some six separate holes in Windows and other Microsoft products were covered by Tuesday's release, including updates to patches for the serious animated cursor flaw for which new exploits continue to emerge, several new vulnerabilities have emerged, although some remain somewhat nebulous. Several reports were issued yesterday, including code carried on cracker sites, of new vulnerabilities in Word, to add to several still remaining unpatched after several months. The latest flaws affect Word 2007, and are thought capable of causing the product, and possibly the system, to crash, and possibly in some cases to allow remote code execution.

More seriously, flaws in Microsoft's DNS service could be used to remotely hijack vulnerable machines, thanks to an overflow issue in the RPC control interface. Users of the service are advised to disable RPC management; an advisory from Microsoft is here, and a Secunia alert is here.
