ID:	200804-14

Synopsis

Multiple vulnerabilities have been discovered in Opera, allowing for execution of arbitrary code.

Background

Opera is a fast web browser that is available free of charge.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-client/opera	< 9.27	>= 9.27	All supported architectures

Description

Michal Zalewski reported two vulnerabilities, memory corruption when adding news feed sources from a website (CVE-2008-1761) as well as when processing HTML CANVAS elements to use scaled images (CVE-2008-1762). Additionally, an unspecified weakness related to keyboard handling of password inputs has been reported (CVE-2008-1764).

Impact

A remote attacker could entice a user to visit a specially crafted web site or news feed and possibly execute arbitrary code with the privileges of the user running Opera.

Workaround

There is no known workaround at this time.

Resolution

All Opera users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/opera-9.27"
