Hi, this AFL is such an insidious thing. :))
The test "ISO" is totally screwed up, except a narrow path that leads to a root directory which bears a Rock Ridge entry "RE". Such an entry marks a directory as relocated. I.e. its Rock Ridge path of directories is not the ECMA-119 path which leads to that directory. A different Rock Ridge path is supposed to exist which points to the directory. But for the root directory, this is of course fatal, as no other path can circumvent it. I have put a patch on that particular pitfall. https://dev.lovelyhq.com/libburnia/libisofs/commit/860a91dd2f05f0fa935e4429ed91fd8b72c911d0 The reaction of xorriso-1.4.7 is now: libisoburn: WARNING : ISO image size 808464432s larger than readable size 20s xorriso : NOTE : Loading ISO image tree from LBA 0 libisofs: FATAL : Root directory is marked by RRIP RE as relocated libisofs: FATAL : Unable to obtain root directory xorriso : FAILURE : Cannot read ISO image tree There is a small memory leak in xorriso_main.c. It is semi-intentional, because the program is bailing out anyways. It has to be expected that other similar crash opportunities exist. Have a nice day :) Thomas
