    (6) LOW: Opera Web Browser Multiple Vulnerabilities

    Affected Products:
    Opera Web browser Version 7

    Description:
    The Opera Web browser contains multiple vulnerabilities that allow a
    malicious web server to read arbitrary files on the client system,
    steal cookies set by other sites, and extract a user's browsing
    history.

    Risk: A malicious web server can harvest sensitive information from
    a client running Opera.

    Deployment: Moderate.
    The Opera browser is ranked third among browsers worldwide behind
    Internet Explorer and Netscape. The software was designed to be
    compact, making it a popular browser solution for embedded devices.
    Opera runs on Windows, OS/2, Linux, BeOS, BelA, Symbian OS, and QNX.

    Ease of Exploitation: Straightforward.
    Example exploits have been posted for each vulnerability.

    Status: These vulnerabilities have not been confirmed by Opera
    Software. They have been corrected in Version 7.01, which is available
    for download from the Opera web site.

    Council Site Actions:
    The majority of the council sites reported the affected software was
    not in production or widespread use, hence no action was necessary.
    One site did have a small deployment, but none of the users had
    installed the affected version.
