FINAL RESULTS:
data/clamsmtp-1.10/common/smtppass.c:1843:13: [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.

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.
if(getenv(name) && !overwrite)
data/clamsmtp-1.10/src/clamsmtpd.c:205:17: [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.

data/clamsmtp-1.10/common/compat.c:272:30: [2] (misc) open:

data/clamsmtp-1.10/common/smtppass.c:1364:19: [2] (tmpfile) mkstemp:
Potential for temporary file vulnerability in some circumstances. Some
older Unix-like systems create temp files with permission to write by all
by default, so be sure to set the umask to override this. Also, some older
Unix systems might fail to use O_EXCL when opening the file, so make sure
that O_EXCL is used by the library (CWE-377).

size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
or automatically resizing strings. Risk is low because the source is a
constant character.

Does not check for buffer overflows when concatenating to destination
