    Mozilla Firefox and Opera Vulnerability

    added February 18, 2008 at 03:34 pm

    US-CERT is aware of public reports of a vulnerability in Mozilla Firefox and Opera web browsers.  This vulnerability is caused by improper handling of bitmap image files (.bmp). By sending a specially crafted bitmap image file to the browser, an attacker may be able to obtain sensitive information or cause a denial-of-service condition.

    US-CERT encourages Mozilla Firefox users to upgrade to Firefox 2.0.0.12 and Opera users to upgrade to Opera 9.25.

    US-CERT will provide more information as it becomes available.


    Public Exploit Code for Microsoft Works Vulnerabilities

    added February 15, 2008 at 08:37 am

    US-CERT is aware of reports of publicly available exploit code for vulnerabilities in Microsoft Works 6 File Converter. By convincing a user to open a specially crafted Works file, an attacker may be able to execute arbitrary code on an affected system. This vulnerability was addressed in Microsoft Security Bulletin MS08-011.

    US-CERT reminds users to review Microsoft Security Bulletin MS08-011 and apply any necessary updates or workarounds. 


    Email Attacks Circulating

    added February 14, 2008 at 03:27 pm

    US-CERT is aware of reports of several email attacks circulating.

    The first of these attacks is related to the U.S. presidential election. The email contains a message indicating that there is a video of a candidate interview available and instructs users to follow a link to download the video. If a user clicks on this link, an executable file will be downloaded that contains the Trojan "Trojan.Srizbi."

    The second attack is a phishing scam related to the U.S. Internal Revenue Service. Messages promising faster or larger refunds may request that users provide personal information or may contain links to phishing websites.

    US-CERT encourages users to take the following preventative measures to mitigate the security risks:
