Flawfinder version 2.0.10, (C) 2001-2019 David A. Wheeler. Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/pspresent-1.3/gs.c Examining data/pspresent-1.3/ps.c Examining data/pspresent-1.3/pspresent.c Examining data/pspresent-1.3/pspresent.h FINAL RESULTS: data/pspresent-1.3/gs.c:47:2: [4] (shell) execvp: This causes a new program to execute and is difficult to use safely (CWE-78). try using a library call that implements the same functionality if available. execvp(args[0], args); data/pspresent-1.3/pspresent.c:624:2: [4] (buffer) strcat: Does not check for buffer overflows when concatenating to destination [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or snprintf (warning: strncat is easily misused). strcat(wm_name, filename); data/pspresent-1.3/pspresent.c:457:14: [3] (buffer) getopt: Some older implementations do not protect against internal buffer overflows (CWE-120, CWE-20). Check implementation on installation, or limit the size of all string inputs. while ((c = getopt(argc, argv, "os:O:hvlt::T:?")) != -1) data/pspresent-1.3/gs.c:39:2: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. char ghostview[32]; data/pspresent-1.3/gs.c:58:2: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. char prop[64]; data/pspresent-1.3/ps.c:49:30: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. static Bool PSGetBoundingBox(char *string, int bounds[4]) data/pspresent-1.3/ps.c:88:21: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. Bool PSScanDocument(char *start, char *end, int bounds[4], int *orientation, data/pspresent-1.3/ps.c:88:34: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).

Bool PSScanDocument(char *start, char *end, int bounds[4], int *orientation, data/pspresent-1.3/ps.c:122:17: [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). pages_size = atoi(line + LEN(DSC_PAGES)) + 1; data/pspresent-1.3/ps.c:156:16: [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). this_page = atoi(line + LEN(DSC_PAGE)); data/pspresent-1.3/pspresent.c:359:7: [2] (misc) open: Check when opening files - can an attacker redirect it (via symlinks), force the opening of special file type (e.g., device files), move things around to create a race condition, control its ancestors, or change its contents? (CWE-362). fd = open(filename, O_RDONLY); data/pspresent-1.3/pspresent.c:422:20: [2] (integer) atoi: Unless checked, the resulting number can exceed the expected range (CWE-190).

(CWE-362). fdelay = fopen(optarg, "r"); data/pspresent-1.3/pspresent.c:623:2: [2] (buffer) strcpy: Does not check for buffer overflows when copying to destination [MS-banned] (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy easily misused). Risk is low because the source is a constant string. strcpy(wm_name, "pspresent: "); data/pspresent-1.3/pspresent.h:52:21: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).
