Flawfinder version 2.0.10, (C) 2001-2019 David A. Wheeler.

(CWE-362). FILE* fp = fopen(path, "w"); data/zathura-djvu-0.2.9/zathura-djvu/djvu.c:462:28: [2] (integer) atoi: Unless checked, the resulting number can exceed the expected range (CWE-190). If source untrusted, check both minimum and maximum, even if the input had no minus sign (large numbers can roll over into negative number; consider saving to an unsigned value if that is intended). target.page_number = atoi(target_string + 2) - 1; data/zathura-djvu-0.2.9/zathura-djvu/djvu.c:707:30: [2] (integer) atoi: Unless checked, the resulting number can exceed the expected range (CWE-190).
