Microsoft releases its Security Bulletins for August 2005
W32/Zotob.A has emerged since the release of Microsoft Security Bulletins for August; a worm that exploits a Plug and Play vulnerability reported in this month's Microsoft Security Bulletin MS05-039 - [KB899588].
Microsoft Windows Security Bulletins for August report the release of three security patches rated "critical", one rated "important" and two rated "moderate". Details of the vulnerabilities these patches pertain to are published in Microsoft's technical summary of August Security Bulletins.
Of the three patches rated "critical", all allowing for potential remote code execution, the patch announced in Microsoft Security Bulletin MS05-038 is of the greatest urgency to most users. One of the vulnerabilities described in this bulletin is a new JPEG image rendering vulnerability in Internet Explorer. This new image rendering vulnerability follows a PNG image rendering vulnerability reported in June 2005 (Microsoft Security Bulletin MS05-025) and the more serious JPEG image rendering vulnerability reported in September 2004 (Microsoft Security Bulletin MS04-028).
Users are advised to patch their systems against these vulnerabilities immediately. Patches can be downloaded via links posted within the appropriate Security Bulletin or by visiting Windows Update and Office Update.
We recommend that users patch their systems by downloading and installing critical Microsoft updates as soon as possible.
Users are also encouraged to update their antivirus software daily and to install a firewall on their computers, if they have not done so already. For more information on firewalls, please read Microsoft's tutorial on how to protect your PC.
