FINAL RESULTS:
data/ikarus-0.0.3+bzr.2010.01.26/src/ikarus-runtime.c:667:11: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
int r = chmod((char*)(path+off_bytevector_data), (mode_t)unfix(mode));
data/ikarus-0.0.3+bzr.2010.01.26/benchmarks.larceny/src/perm9.c:549:5: [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( msg );
data/ikarus-0.0.3+bzr.2010.01.26/benchmarks.larceny/src/string.c:18:25: [4] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.
sprintf(p, "123%s456%s789", s, s);
data/ikarus-0.0.3+bzr.2010.01.26/benchmarks.larceny/src/string.c:23:25: [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(p, s + len/2);
data/ikarus-0.0.3+bzr.2010.01.26/src/ikarus-process.c:160:7: [4] (shell) execvp:
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.
execvp(cmd_str, argv_strs);
data/ikarus-0.0.3+bzr.2010.01.26/src/ikarus-process.c:162:7: [4] (shell) execv:
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.
execv(cmd_str, argv_strs);
data/ikarus-0.0.3+bzr.2010.01.26/src/ikarus-runtime.c:709:13: [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.
int r = system((char*)(long)(str+off_bytevector_data));
data/ikarus-0.0.3+bzr.2010.01.26/src/ikarus-runtime.c:1084:7: [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.
r = access(fn, c_how);
data/ikarus-0.0.3+bzr.2010.01.26/src/ikarus.c:53:3: [4] (format) fprintf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
fprintf(stderr, helpstring, BOOTFILE);
data/ikarus-0.0.3+bzr.2010.01.26/src/ikarus-process.c:65:16: [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.
searchpath = getenv("PATH");
data/ikarus-0.0.3+bzr.2010.01.26/src/ikarus-runtime.c:695:13: [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.
char* p = realpath((char*)(bv+off_bytevector_data), buff);
data/ikarus-0.0.3+bzr.2010.01.26/src/ikarus-runtime.c:924:13: [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.
