FINAL RESULTS:
data/conman-0.2.7/client-conf.c:70:14: [4] (misc) getlogin:
It's often easy to fool getlogin. Sometimes it does not work at all,
because some program messed up the utmp file. Often, it gives only the
first 8 characters of the login name. The user currently logged in on the
controlling tty of our program need not be the user who started it. Avoid
getlogin() for security-related purposes (CWE-807). Use getpwuid(geteuid())
and extract the desired information instead.
if ((p = getlogin()) || (p = getenv("USER")) || (p = getenv("LOGNAME")))
data/conman-0.2.7/log.c:79:9: [4] (format) vfprintf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
vfprintf(stderr, format, vargs);
data/conman-0.2.7/log.c:223:9: [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.
n = vsnprintf(p, len, format, vargs);
data/conman-0.2.7/server-conf.c:848:13: [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.
