FINAL RESULTS:
data/prelink-0.0.20131005/src/canonicalize.c:263:12: [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 (rpath, buf, path_max);
data/prelink-0.0.20131005/src/dso.c:768:3: [4] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.
sprintf (filename, "%s.#prelink#.XXXXXX", temp_base);
data/prelink-0.0.20131005/src/execstack.c:108:3: [4] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.
sprintf (filename, "%s.#execstack#.XXXXXX", dso->filename);
data/prelink-0.0.20131005/src/execstack.c:130:7: [4] (shell) execlp:
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.
execlp ("prelink", "prelink", "-u", "-o", filename,
data/prelink-0.0.20131005/src/execstack.c:132:7: [4] (shell) execl:
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.
execl (SBINDIR "/prelink", "prelink", "-u", "-o", filename,
data/prelink-0.0.20131005/src/gather.c:631:3: [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 (dir->dir, canon_name);
data/prelink-0.0.20131005/src/gather.c:1350:3: [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 (path->dir, canon_name);

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 (stpcpy (p, "LD_TRACE_PRELINKING="), info->ent->filename);
data/prelink-0.0.20131005/src/main.c:261:7: [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.
system("/sbin/init U");
data/prelink-0.0.20131005/src/main.c:328:9: [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.
if (! access ("/proc/sys/kernel/exec-shield", F_OK))
data/prelink-0.0.20131005/src/makecrc.c:59:5: [4] (format) printf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
printf(i % 5 ? ", 0x%08lx" : ",\n 0x%08lx", c);
data/prelink-0.0.20131005/src/layout.c:403:4: [3] (random) srandom:
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.
srandom (mmap_start >> 12);
data/prelink-0.0.20131005/src/layout.c:405:25: [3] (random) random:
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.
l.libs[i]->u.tmp = random ();
data/prelink-0.0.20131005/src/main.c:345:23: [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.
ld_library_path = getenv ("LD_LIBRARY_PATH");

data/prelink-0.0.20131005/src/cache.c:367:8: [2] (misc) open:
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).

Potential for temporary file vulnerability in some circumstances. Some
older Unix-like systems create temp files with permission to write by all
