  • Comment: Bad XDS bytes segfault zvbi

    It looks like there's a "Start Miscellaneous" XDS code in there with a sub-code of 0x18. As best as I can tell, 0x18 is illegal (they go up to 0x17). This is accessing an array element in cc->sub_packet[][] that is beyond the end of the array.

  • Bad XDS bytes segfault zvbi

    I have a video file with bad (and possibly missing) XDS bytes. This causes libzvbi to not just choke, but segfault with a dereference on a bad pointer. I've distilled the section of picture-user bytes into a byte array within a test application to make this easily repeatable (attached). Expected behavior: the library shouldn't segfault on bad slice data. (gdb) bt #0 xds_separator...
