When viewing http://www.mediaatlantic.com/Downloads/avermedia/A808_AVerTV_DVB-T_Volar.pdf , I find evince crashes:

Installing debug packages and running with valgrind, we see memory violation via stack corruption (which happens to be caught by GCC this time), thus this has potential to be a security violation:
