FINAL RESULTS:
data/libre-1.1.0/src/sa/ntop.c:154:2: [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(dst, tmp);
data/libre-1.1.0/src/sys/sys.c:202:11: [4] (misc) getlogin:
It's often easy to fool getlogin. Sometimes it does not work at all,
because some program messed up the utmp file. Often, it gives only the
first 8 characters of the login name. The user currently logged in on the
controlling tty of our program need not be the user who started it. Avoid
getlogin() for security-related purposes (CWE-807). Use getpwuid(geteuid())
and extract the desired information instead.
login = getlogin();
data/libre-1.1.0/src/dns/win32/srv.c:40:9: [3] (misc) LoadLibrary:
Ensure that the full path to the library is specified, or current directory
may be used (CWE-829, CWE-20). Use registry entry or GetWindowsDirectory to
find library path, if you aren't already.
hLib = LoadLibrary(TEXT("iphlpapi.dll"));
data/libre-1.1.0/src/lock/win32/lock.c:38:2: [3] (misc) InitializeCriticalSection:
Exceptions can be thrown in low-memory situations. Use
InitializeCriticalSectionAndSpinCount instead.
InitializeCriticalSection(&l->c);
data/libre-1.1.0/src/lock/win32/lock.c:47:2: [3] (misc) EnterCriticalSection:
On some versions of Windows, exceptions can be thrown in low-memory
situations. Use InitializeCriticalSectionAndSpinCount instead.
EnterCriticalSection(&l->c);
data/libre-1.1.0/src/lock/win32/lock.c:53:2: [3] (misc) EnterCriticalSection:
On some versions of Windows, exceptions can be thrown in low-memory
situations. Use InitializeCriticalSectionAndSpinCount instead.
EnterCriticalSection(&l->c);
data/libre-1.1.0/src/net/win32/wif.c:39:9: [3] (misc) LoadLibrary:
Ensure that the full path to the library is specified, or current directory
may be used (CWE-829, CWE-20). Use registry entry or GetWindowsDirectory to
find library path, if you aren't already.
hLib = LoadLibrary(TEXT("iphlpapi.dll"));
data/libre-1.1.0/src/sys/rand.c:50:2: [3] (random) srand:
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.
srand((uint32_t) tmr_jiffies());
data/libre-1.1.0/src/sys/sys.c:197:10: [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.
login = getenv("LOGNAME");
data/libre-1.1.0/src/sys/sys.c:199:11: [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.
login = getenv("USER");
