Under "Secure Browsing" for IE 9, VLC media player 1.x is listed as "Unpatched, no vendor solution".

In fact, there is no VLC media player plugin for Internet Explorer, and there never has been. The Status and Advisory links are directed to the listing about the *Mozilla* plugin.

I've given up on expecting the issue of "detection" of the Mozilla plugin when it is not even installed for Mozilla; that false detection of a non-installed plugin will apparently never be fixed. I've never had the plugin installed, yet PSI always has claimed it is making Firefox "not secure".

But claiming that the same Mozilla plugin somehow also makes IE 9 "Not secure for browsing"? What is THAT?

Did I mention that the plugin is not installed on my system at all anyway?

I'm sure this will somehow be blamed on VideoLAN or Microsoft.

Have you tried double clicking on the entry in Secure Browsing (tho' there's no + sign on the left of ), after having clicked alongside the main IE/Mozilla entry should present you with a Quick facts panel which should include details and File Path etc..

Hope this helps........regards,

Yes, I have tried double-clicking on the program name, and it is not helpful. I know the path/filename/etc. I'm very familiar with the program - enough to know (unlike PSI) that there is no IE 9 plug-in for VLC Media player.

In fact, double-clicking the program takes me to the information about the program itself, and not the plugin, which is yet another misfeature of PSI. I'm glad you mentioned it - it's not really germane - but it is quite misleading that double-clicking at that point on ANY plug-in doesn't tell you about the plug-in itself in cases like this where the plug-in is ancillary to, or an optional feature of, another installed program.

In any case, in the secure browsing page, under the supposed "IE 9 plug-in" for VLC Media Player, I have clicked where it says "Unpatched, no vendor solution", and where it says "SA41810", and both links take me to information about the Mozilla plug-in for VLC Media Player.

So... two issues:

1. There is no IE 9 plug-in, and IE doesn't use the Mozilla plug-in, therefore PSI is falsely reporting that my IE 9 browser is not secure.

2. I don't even have the Mozilla plug-in installed, therefore PSI is also falsely reporting that my Firefox browser is not secure.

My point is: false reporting undermines my confidence in the secure browsing part of PSI, and therefore in PSI and CSI overall. If I can't trust what PSI says about this, how can I trust the other things it reports?

The best thing I can say about this is that it displays a lack of attention to detail.

@msimpson baymcp

Understandably frustrating. To be clear go to the Secure Browsing feature/ on the + sign alongside IE or FF...and in both cases an entry for the VLC plug-in is shown, for both, as vulnerable ? You then click on either/each of the plug-in entries, and a panel appears but with no filepath to : it takes you to info about the program ? Have I got it correct ?
I know there's still outstanding consternation on at least one other thread....where users do have the plug-in....and even so havn't got a resolution.
In my experience if Secunia has detected an insecurity it's usually found something; but obviously; if you can't find the file can't go any further.
I can only think that it's a matter of detection rules being amended. That of course won't be till after the holiday.....when hopefully Support will pick up on this thread.

Hi ,

This subject is almost done to death , it just won't lie down .

The default installation of the VLC Player version 1.1.9 is with the "Mozilla Plug-in" not selected but with the "ActiveX" selected , as in for IE , as in the same for Flash Player for example . This is what will be showing/detected by the PSI in IE9 .

The problem of the "secure browsing" detection is a known and accepted bug and cannot be rectified by changing the PSI detection rules at the moment .

Secunia are on record as looking/trying to find a solution :-

Also , try reading here :-

I am unsure why "a" known , established and accepted bug would cause someone to put the whole concept and reliability of Secunia , the CSI , the PSI and the OSI at risk !! Nothing , except death and taxes , is 100% guaranteed , so a little imagination is paramount .

VideoLAN have not fixed the "Mozilla" bug and have/cannot change their bundling , nor do they seem likely to do anything with the "plug-in" saga for the forseeable future ; probably because they are short of developers as per this and the contained Forum link(s) :-

Enjoy the Easter break :))

Take care



It always seems impossible until its done.

The Secure Browsing section is only intended for advanced users. The information presented here can be less "polished" and so may require some technical knowledge to use.

In the case of VLC, it is not possible for the PSI to discriminate on configuration changes. As such, VLC is grouped for both NPAPI and activex (only IE) browsers, because this is the surface it might expose to vulnerabilities.

hope this helps.

[Edit] Actually, I am rescinding what I said here, after reading the links finally provided which show that VideoLan has let this vulnerability exist since 2008!

In that case, I am happy enough to be warned to the extent that I removed this recent install from my machine, precision errors of reporting or not.

I'd installed it in the first place because of persistent slant that VLC might be more secure than original video players. Clearly not the case, and with all due regard to having a prominent developer leave. Perhaps the issue in gaining another has to do with uncertainty surrounding replicated codecs, etc., which is another question about VLC.

Again (if you read the original comment), Emil, I do appreciate the challenge in what Secunia does, and appreciate what it provides.
