CVE-2007-3456
CVE-2007-3457


Description:
Some vulnerabilities have been reported in Adobe Flash Player, which can be exploited by malicious people to gain knowledge of sensitive information or compromise a user's system.

1) A boundary error when processing FLV files can be exploited to cause a buffer overflow via an FLV file with a specially crafted DataObject section.

Successful exploitation allows execution of arbitrary code when a user e.g. visits a malicious website.

The vulnerability affects versions 9.0.45.0 and prior.

2) An error within the interaction of Flash Player and certain browsers can be exploited to leak key presses to a Flash Player applet.

The vulnerability affects versions 7.0.69.0 and prior on Linux and Solaris. It does not affect Flash Player 9.

A bug has also been reported in the validation of the HTTP Referer in versions 8.0.34.0 and prior, which may aid in e.g. CSRF (Cross-Site Request Forgery) attacks.

Solution:
Apply updates.
