FINAL RESULTS:
data/ffmpegfs-2.0/src/ffmpeg_utils.cc:1072:21: [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.
ssize_t count = readlink("/proc/self/exe", result, PATH_MAX);
data/ffmpegfs-2.0/src/fuseops.cc:674:11: [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.
len = readlink(origpath.c_str(), buf, size - 2);
data/ffmpegfs-2.0/src/ffmpeg_utils.cc:690:9: [4] (buffer) strcat:
Does not check for buffer overflows when concatenating to destination
[MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
snprintf (warning: strncat is easily misused).
strcat(dir, p);
data/ffmpegfs-2.0/src/ffmpeg_utils.cc:1120:39: [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.
size_t size = static_cast<size_t>(snprintf(nullptr, 0, format.c_str(), args ...) + 1); // Extra space for '\0'
data/ffmpegfs-2.0/src/ffmpeg_utils.cc:1122:10: [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.
std::snprintf(buf.get(), size, format.c_str(), args ...);
data/ffmpegfs-2.0/src/ffmpeg_utils.cc:1321:13: [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.
return (access(filename.c_str(), F_OK) != -1);
data/ffmpegfs-2.0/src/logging.h:322:56: [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.
size_t size = static_cast<size_t>(std::snprintf(nullptr, 0, res[2].str().c_str(), val)) + 1;
data/ffmpegfs-2.0/src/logging.h:325:22: [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.
std::snprintf(buffer.data(), size, res[2].str().c_str(), val);

(e.g., by moving files), the attacker can exploit the race condition

data/ffmpegfs-2.0/src/ffmpeg_utils.cc:714:24: [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.
const char *temp = getenv("TMPDIR");
data/ffmpegfs-2.0/src/ffmpeg_utils.cc:1250:9: [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.

data/ffmpegfs-2.0/src/transcode.cc:194:47: [3] (buffer) getenv:
