#Firefox upnp player manual

“They do not need to access any malicious websites or click any malicious links.

“The target simply has to have the Firefox application running on their phone,” he explained. To exploit the bug, an attacker would need to be attached to the same Wi-Fi network as the target, according to researcher Chris Moberly, who recently published details on the bug, along with a proof-of-concept (PoC) exploit. This can be used for various malicious attacks, or as the researcher points out, surprising victims with an auto-playing Rick Astley video. The attack manifests in the form of a Firefox browser window on the target device suddenly launching, without the users’ permission.

#Firefox upnp player manual

You might want to say something like that in the manual (or suppress the option if that's not too hard).A vulnerability in Firefox for Android paves the way for an attackers to launch websites on a victim’s phone, with no user interaction. As I understand it, if only 'raw' is specified, the 'No Higher' option should not be available because there is no way to make it work. It's a bit silly from UPnP standard because, they could, as for wav, discover the sample rate and size with the audio data as, although it's not *inside* the data, HTTP requires content-type header to set explicitly these informations when starting to send audio. I know we are in the context of tests, and not trying to find a working configuration, but I did not fully got the precise problem. So, in that case, if raw is allowed, I used it On the contrary, when you fix sample rate and sample size, then the bridge knows that it will have to do whatever is needed to reach these sample rate and size, which also means that it can indicate them to the UPnP player in the early play message. So, in that case, I have to remove 'raw' from allowed format and because this is the only one you have set in 'PCM format', it fails. And that's too late, as the play command as already been sent to the UPnP player Unfortunately, when LMS sends a play request for a compressed format (flac in your case), it does not tell what are the sample rate and size, the bridge discovers it when it starts receiving the actual audio. When trying to send pcm (audio/Lss) to a UPnP player, you must tell, at that early stage, what is the sample size and sample rate. : and I know what's happening! This is related to the long post I wrote beforeĭue to UPnP protocol, the bridge must send the UPnP play request as soon as it receives the play request from LMS, and that's before any audio data has arrived. : and I'm sorry for being thick, I'm probably doing (trying to do) too many things in parallel here when set to 96000 with the 'no higher' option ticked, it fails when resampling rate is force to fixed 96000, its fine So, let me try to resume: all other things being equal, It's only when I place the limit that nothing at all works in raw.Oh, Sorry Tim I got it now. I know it will work in raw 96000, and even 192000. (BTW I posted the abilities a few posts ago). I know I can get the music to play, that's not the aim of my tests for you. It's only when I place the limit that nothing at all works in raw.īut wait a minute. To me that means there's something wrong the the ticked logic. The only issue is that with the one tick box unticked it's all fine in raw (only) but with it ticked nothing plays. audio/Lss) format but sample rate up to 96000 - you're precise, but all these criteria must match a player capabilityĪ more 'relaxed' setting is to have 'raw,wav' in 'PCM format' so that the transcoded 24 bits audio can be sent in 'wav' if no audio/L24 rate=rrrrr is foundBut wait a minute. Here you want 24 bits (in 'packed' mode), you've authorized only 'raw' (i.e. Because if it does not, then it is why there is no matching. I do not remember if its protocolInfo authorizes up to audio/L24 rate=96000. So, the M1 config has 'raw' only authorized in uncompressed format (the log says you play on the M1).
