Opening .avi file is crashing Winamp 5.571

praveen_recker · 4th January 2010, 19:28

Created a file with name, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.avi

Opening file with this name crashes Winamp v5.571

I tested this on Windows7 Ultimate.

Add .avi extension to the attached file and open with Winamp

I can reproduce it on XP
an empty "a.avi" file is enough

it crashes in the in_avi plugin

It crashes explorer.exe for me...
Though I think that was the explorer preview using ffdshow to blame.

But yeah, we'll need to fix 0 byte AVI files crashing.
Is it just AVI, or are any other formats affected, eg. MKV or MP4/M4V?

I wasn't sure at first if it was the 0 byte factor or the filename length to blame... or both.

I can't reproduce this with other media file name extensions

LE: I've uninstalled ffdshow, it still crashes

Hello Friends,

Crash is not due to long avi file name...the CRASH is due to zero size avi file.
I tried few other extensions but didn't observe this bug.

I wanted to directly report to Winamp guys but couldn't get any Email-ID so ended up in posting the forum.

Hi DJ Egg.....Can I make it public, like disclosing at securityfocus.com and obtain CVE ID from MITRE or wait until the bug is fixed.

DJ Egg · 10th January 2010, 20:04

This should fix it....

Nullsoft AVI Demuxer v0.3 [in_avi.dll]

I'm having the same problem, but it happens with ANY avi file, regardless of name or size.

They play fine in all other players, but crash Winamp on open.

I have the latest codecs and Winamp version.

Everything worked until a week or so ago...
