After this address is freed, vlc then attempts to free the next four bytes in the file, 0x1122331e. This data can be changed in the sample_crash file to free two arbitrary addresses. sample_crash : http://s000.tinyupload.com/?file_id=94915905821495818830 <http://s000.tinyupload.com/index.php?file_id=94915905821495818830> -Loren Maggiore Content of type "text/html" skipped Download attachment "smime.p7s" of type "application/pkcs7-signature" (3869 bytes)
