A vulnerability has been reported in Adobe Flash Player, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an error in the ActionScript Virtual Machine 2 (AVM2) when handling the "newfunction()" method. This can be exploited to incorrectly calculate the location of a pointer later used to obtain an object reference, which may result in execution of user-controlled data in memory.

Successful exploitation allows execution of arbitrary code.

The vulnerability is reported in version 10.0.45.2 and prior 10.0.x and 9.0.x versions for Windows, Macintosh, Linux, and Solaris.

NOTE: The vulnerability is reportedly being actively exploited.

Hi motty

By making a comment after a Secunia Advisory, creates a thread under the Vulnerabilities sub-heading, where a lot of members are reluctant to post replies, due to negative scoring and post minimising.
It is always better to create your own thread, under one of the other sub-headings (despite comments/replies being invited after an Advisory).

However your action is correct (and is the same as I and others have done).

As this RC7 Flash is still release candidate and not full release version update, PSI recognises this as secure under patched, but only as a workaround under secure browsing (and not a full solution), hence the browser boxes still showing red.

Both Secunia and Adobe report the latest RC7 flash as not effected by the vulnerability - so you should be secure, despite the PSI reporting conflicts.

One further point - perhaps here is not the best place to promote non-related links.
