Examining data/elementary-xfce-0.15.1/svgtopng/svgtopng.c

FINAL RESULTS:

data/elementary-xfce-0.15.1/svgtopng/svgtopng.c:58:15:  [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).
  icon_size = atoi (basename);
data/elementary-xfce-0.15.1/svgtopng/svgtopng.c:66:25:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
  tmp = g_strndup (src, strlen (src) - 3);
data/elementary-xfce-0.15.1/svgtopng/svgtopng.c:78:38:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
              tmp = g_strndup (link, strlen (link) - 3);

Symlinks skipped = 9 (--allowlink overrides but see doc for security issue)
Dot directories skipped = 1 (--followdotdir overrides)
Minimum risk level = 1
Not every hit is necessarily a security vulnerability.
There may be other security vulnerabilities; review your code!
