Macromedia Flash Player: Remote arbitrary code execution

Background

The Macromedia Flash Player is a renderer for the popular SWF file type which is commonly used to provide interactive websites, digital experiences and mobile content.

Description

Mark Hills discovered some errors when interacting with a browser for keystrokes handling (CVE-2007-2022). Stefano Di Paola and Giorgio Fedon from Minded Security discovered a boundary error when processing FLV files (CVE-2007-3456). An input validation error when processing HTTP referrers has also been reported (CVE-2007-3457).

Impact

A remote attacker could entice a user to open a specially crafted file, possibly leading to the execution of arbitrary code with the privileges of the user running the Macromedia Flash Player, or sensitive data access.

Workaround

There is no known workaround at this time.

Resolution

All Macromedia Flash Player users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=www-plugins/adobe-flash-9.0.48.0"
