FINAL RESULTS:
data/colorhug-client-0.2.8/src/ch-ccmx.c:1762:37: [3] (buffer) g_get_home_dir:
This function is synonymous with 'getenv("HOME")';it returns untrustable
input if the environment can beset by an attacker. It 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.
current_folder = g_build_filename (g_get_home_dir (),
data/colorhug-client-0.2.8/src/ch-main.c:2822:13: [3] (random) g_random_int_range:
This function is not sufficiently random for security-related functions
such as key and nonce creation (CWE-327). Use a more secure technique for
acquiring random values.
data[i] = g_random_int_range (0x00, 0xff);
data/colorhug-client-0.2.8/src/ch-self-test.c:42:8: [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.
tmp = realpath (path, full_tmp);
data/colorhug-client-0.2.8/src/ch-flash.c:536:2: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy (priv->firmware_data,
data/colorhug-client-0.2.8/src/ch-self-test.c:39:2: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.
char full_tmp[PATH_MAX];
