FINAL RESULTS:
data/r-cran-pbdzmq-0.3.3.1+dfsg/src/R_zmq_message.c:56:3: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy(zmq_msg_data(&msg), RAW(R_rmsg), C_rmsg_length);
data/r-cran-pbdzmq-0.3.3.1+dfsg/src/R_zmq_message.c:101:3: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy(RAW(R_rmsg), zmq_msg_data(&msg), C_rmsg_length);
data/r-cran-pbdzmq-0.3.3.1+dfsg/src/R_zmq_transfer.c:61:18: [2] (misc) fopen:
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).
FILE *infile = fopen(CHARPT(R_filename, 0), "r");
data/r-cran-pbdzmq-0.3.3.1+dfsg/src/R_zmq_transfer.c:113:19: [2] (misc) fopen:
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).

data/r-cran-pbdzmq-0.3.3.1+dfsg/src/R_zmq_utility.c:29:2: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.
char ver[36];
data/r-cran-pbdzmq-0.3.3.1+dfsg/src/R_zmq_utility.c:36:10: [2] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf. Risk is low because the source has a constant maximum length.
chars = sprintf(ver, "%d.%d.%d", major, minor, patch);
data/r-cran-pbdzmq-0.3.3.1+dfsg/src/shellexec_wcc.c:38:9: [2] (buffer) wchar_t:
Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.
static wchar_t filename[BSIZE + 1];
data/r-cran-pbdzmq-0.3.3.1+dfsg/src/shellexec_wcc.c:76:2: [2] (buffer) wchar_t:
Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.

data/r-cran-pbdzmq-0.3.3.1+dfsg/src/R_zmq_socket.c:113:20: [1] (buffer) strlen:
Does not handle strings that are not \0-terminated; if given one it may
perform an over-read (it could cause a crash if unprotected) (CWE-126).
C_option_len = strlen(C_option_value);
data/r-cran-pbdzmq-0.3.3.1+dfsg/src/R_zmq_socket.c:150:20: [1] (buffer) strlen:
Does not handle strings that are not \0-terminated; if given one it may
perform an over-read (it could cause a crash if unprotected) (CWE-126).
C_option_len = strlen(C_option_value);
data/r-cran-pbdzmq-0.3.3.1+dfsg/src/shellexec_wcc.c:44:6: [1] (buffer) strlen:
Does not handle strings that are not \0-terminated; if given one it may
perform an over-read (it could cause a crash if unprotected) (CWE-126).
if(!strlen(CHAR(fn))){
data/r-cran-pbdzmq-0.3.3.1+dfsg/src/shellexec_wcc.c:45:3: [1] (buffer) wcscpy:
Does not check for buffer overflows when copying to destination [MS-banned]
(CWE-120). Consider using a function version that stops copying at the end
of the buffer. Risk is low because the source is a constant character.
wcscpy(filename, L"");
data/r-cran-pbdzmq-0.3.3.1+dfsg/src/shellexec_wcc.c:60:8: [1] (buffer) strlen:
Does not handle strings that are not \0-terminated; if given one it may
perform an over-read (it could cause a crash if unprotected) (CWE-126).
inb = strlen(inbuf)+1; outb = 2*BSIZE;
data/r-cran-pbdzmq-0.3.3.1+dfsg/src/shellexec_wcc.c:82:3: [1] (buffer) wcsncpy:
Easily used incorrectly; doesn't always \0-terminate or check for invalid
pointers [MS-banned] (CWE-120).
wcsncpy(home2, home, 10000);
