[Bug 275565] Re: vlc crashed with SIGSEGV in LibavutilCallback()
regarding vlc_crash.mpg, it's a bug in libavcodec. ffplay crash also on it. (well very recent ffplay from svn doesn't really crash but get stuck) Running a debug version of vlc yields: *** glibc detected *** ./bin/vlc-static: free(): invalid pointer: 0xb2520020 *** === Backtrace: = /lib/i686/cmov/libc.so.6[0xb7c01624] /lib/i686/cmov/libc.so.6(cfree+0x96)[0xb7c03826] ./modules/codec/avcodec/.libs/libavcodec_plugin.so(av_freep+0x16)[0xb4bd6f56] /data/dev/videolan/vlc/linux/src/.libs/libvlccore.so.2(__module_unneed+0x2f)[0xb7e9a09f] /data/dev/videolan/vlc/linux/src/.libs/libvlccore.so.2(input_DecoderDelete+0x95)[0xb7e4c625] and gdb says: #0 0xb7ef1424 in __kernel_vsyscall () #1 0xb7ba7640 in raise () from /lib/i686/cmov/libc.so.6 #2 0xb7ba9018 in abort () from /lib/i686/cmov/libc.so.6 #3 0xb7be434d in __libc_message () from /lib/i686/cmov/libc.so.6 #4 0xb7bea624 in malloc_printerr () from /lib/i686/cmov/libc.so.6 #5 0xb7bec826 in free () from /lib/i686/cmov/libc.so.6 #6 0xb7449f56 in av_freep (arg=0x9195198) at libavutil/mem.c:128 #7 0xb708ff11 in avcodec_default_free_buffers (s=0x91ad2c0) at libavcodec/utils.c:824 #8 0xb71c1c45 in ff_h263_decode_end (avctx=0x91ad2c0) at libavcodec/h263dec.c:126 #9 0xb70912f7 in avcodec_close (avctx=0x91ad2c0) at libavcodec/utils.c:575 #10 0xb7084eb9 in CloseDecoder (p_this=0x91a8428) at ../../../../modules/codec/avcodec/avcodec.c:315 #11 0xb7e8309f in __module_unneed (p_this=0x91a8428, p_module=0x9131bb0) at ../../src/modules/modules.c:681 (Can't comment on the youtube one as the video has been removed) -- vlc crashed with SIGSEGV in LibavutilCallback() https://bugs.launchpad.net/bugs/275565 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm not sure this is the exact same as my bug, but I've attached the exact .mpg file that caused the crash I reported.

I'm not able to play this mpeg file with anything (nor mplayer, avidemux, ..)

[Bug 275565] Re: vlc crashed with SIGSEGV in LibavutilCallback()
I think the point is that this file is actually corrupt (iirc he said something like this in the duplicate bug). But even if the file is corrupted is must not crash vlc player. ** Changed in: vlc (Ubuntu) Status: Incomplete = Confirmed -- vlc crashed with SIGSEGV in LibavutilCallback() https://bugs.launchpad.net/bugs/275565 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 275565] Re: vlc crashed with SIGSEGV in LibavutilCallback()
Yes, that's correct. The file is corrupt and won't play in any player. However, VLC also runs as a browser plugin so this bug could be used to crash people's browser remotely. It's not at all inconceivable that this bug also opens for remote code execution (if it's some form of buffer or integer overflow for example). -- vlc crashed with SIGSEGV in LibavutilCallback() https://bugs.launchpad.net/bugs/275565 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

A lot of memory leaks has been fixed with vlc 0.9.4. As the video is not available anymore, and that I've not been able to reproduce the problem, can you test the last vlc version?
