data/crashme-2.8.5/vnsq.c:27:3: [2] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf. Risk is low because the source has a constant maximum length.
sprintf (decimalrep, "%lu", nextn);
data/crashme-2.8.5/vnsq.c:36:20: [2] (integer) atol:
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).
vnsq_value = atol (nextp);
data/crashme-2.8.5/crashme.c:280:3: [1] (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). Risk is low because the
source is a constant character.
strcat (note_buffer, "\n");
data/crashme-2.8.5/crashme.c:606:29: [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).
notes = note_buffer + strlen (note_buffer);
data/crashme-2.8.5/crashme.c:619:29: [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).

data/crashme-2.8.5/crashme.c:639:11: [1] (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). Risk is low because the
source is a constant character.

data/crashme-2.8.5/crashme.c:939:3: [1] (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 character.
strcpy (notes, "");
data/crashme-2.8.5/vnsq.c:28:20: [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).
