FINAL RESULTS:
data/libaacs-0.9.0/src/file/path.c:101:13: [5] (race) readlink:
This accepts filename arguments; if an attacker can move those files or
change the link content, a race condition results. Also, it does not
terminate with ASCII NUL. (CWE-362, CWE-20). Reconsider approach.
n = readlink(resolved_path, link, AACS_PATH_MAX - 1);
data/libaacs-0.9.0/src/file/dirs_xdg.c:104:13: [4] (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).
strcpy(dirs, xdg_sys);
data/libaacs-0.9.0/src/file/keydbcfg.c:550:51: [4] (shell) system:
This causes a new program to execute and is difficult to use safely
(CWE-78). try using a library call that implements the same functionality
if available.

data/libaacs-0.9.0/src/util/logging.c:76:9: [4] (format) vsnprintf:
If format strings can be influenced by an attacker, they can be exploited,

a constant for the format specification.
vsnprintf(pt, sizeof(buffer) - (size_t)(intptr_t)(pt - buffer) - 1, format, args);
