FINAL RESULTS:
data/libmypaint-1.6.0/tests/mypaint-test-surface.c:95:5: [4] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.
sprintf(png_filename, "%s.png", data->test_case_id);
data/libmypaint-1.6.0/tests/mypaint-test-surface.c:115:23: [4] (format) snprintf:
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.
char *id = malloc(snprintf(NULL, 0, templ, title) + 1);
data/libmypaint-1.6.0/tests/mypaint-test-surface.c:116:5: [4] (format) sprintf:
Potential format string problem (CWE-134). Make format string constant.
sprintf(id, templ, title);
data/libmypaint-1.6.0/tests/mypaint-benchmark.c:61:22: [3] (buffer) getenv:
Environment variables are untrustable input if they can be set by an
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.
char * enabled = getenv("MYPAINT_ENABLE_PROFILING");
data/libmypaint-1.6.0/mypaint-rectangle.c:28:13: [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(p, src, len);
data/libmypaint-1.6.0/tests/mypaint-test-surface.c:155:5: [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 test_ids[num_cases][max_id_length];
data/libmypaint-1.6.0/tests/testutils.c:15:18: [2] (misc) fopen:
Check when opening files - can an attacker redirect it (via symlinks),
force the opening of special file type (e.g., device files), move things
around to create a race condition, control its ancestors, or change its
contents? (CWE-362).
FILE *file = fopen(path, "r");
