Secunia Research has discovered a vulnerability in Windows XP, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a use-after-free error in the bundled version of Flash Player when unloading Flash objects while these are still being accessed using script code. This can be exploited to corrupt memory via a specially crafted web page.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in Flash Player bundled with a fully patched Windows XP SP2 and is also confirmed in an old version 6.0.79 of Adobe Flash Player.

NOTE: The version of Flash Player bundled with Windows XP is also affected by a number of other vulnerabilities previously disclosed and fixed in later versions of Adobe Flash Player.

Solution
Uninstall the bundled version of Flash Player and optionally install the latest supported version of Flash Player from Adobe.
