FINAL RESULTS:
data/imv-4.1.0/src/imv_msg.c:32:5: [5] (buffer) strncat:
Easily used incorrectly (e.g., incorrectly computing the correct maximum
size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
or automatically resizing strings. Risk is high; the length parameter
appears to be a constant, instead of computing the number of characters
left.
strncat(buf, argv[i], sizeof buf - 1);
data/imv-4.1.0/src/imv_msg.c:34:7: [5] (buffer) strncat:
Easily used incorrectly (e.g., incorrectly computing the correct maximum
size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
or automatically resizing strings. Risk is high; the length parameter
appears to be a constant, instead of computing the number of characters
left.
strncat(buf, " ", sizeof buf - 1);
data/imv-4.1.0/src/imv_msg.c:37:3: [5] (buffer) strncat:
Easily used incorrectly (e.g., incorrectly computing the correct maximum
size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
or automatically resizing strings. Risk is high; the length parameter
appears to be a constant, instead of computing the number of characters
left.
strncat(buf, "\n", sizeof buf - 1);
data/imv-4.1.0/src/binds.c:281:16: [4] (format) snprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.
printed += snprintf(buf, len - printed, format, key);
data/imv-4.1.0/src/canvas.c:135:3: [4] (format) vsnprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.
vsnprintf(line, sizeof line, fmt, args);
data/imv-4.1.0/src/imv.c:1257:20: [4] (race) access:
This usually indicates a security flaw. If an attacker can change anything
along the path between the call to access() and the file's actual use
(e.g., by moving files), the attacker can exploit the race condition
(CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
and try to open the file directly.
if (!path || access(path, R_OK) == -1) {
data/imv-4.1.0/src/imv.c:1569:3: [4] (shell) system:
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.
system(argstr);
data/imv-4.1.0/src/log.c:29:3: [4] (format) vsnprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.
vsnprintf(g_log_buffer, sizeof g_log_buffer, fmt, args);
data/imv-4.1.0/src/imv.c:744:15: [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 ((o = getopt(argc, argv, "frdxhvlu:s:n:b:t:c:")) != -1) {
data/imv-4.1.0/src/ipc_common.c:8:22: [3] (buffer) getenv:
Environment variables are untrustable input if they can be set by an
attacker. They can have any content and length, and the same variable can
be set more than once (CWE-807, CWE-20). Check environment variables
carefully before using them.
const char *base = getenv("XDG_RUNTIME_DIR");
data/imv-4.1.0/src/navigator.c:56:20: [3] (buffer) realpath:
This function does not protect against buffer overflows, and some
implementations can overflow internally (CWE-120/CWE-785!). Ensure that the
destination buffer is at least of size MAXPATHLEN, andto protect against
implementation problems, the input argument should also be checked to
ensure it is no larger than MAXPATHLEN.
nav_item->path = realpath(path, NULL);
data/imv-4.1.0/src/backend_libjpeg.c:77:16: [2] (misc) open:

around to create a race condition, control its ancestors, or change its
contents? (CWE-362).

memcpy(new_private, &private, sizeof private);
data/imv-4.1.0/src/backend_libnsgif.c:86:3: [2] (buffer) memcpy:
