FINAL RESULTS:
data/libnative-platform-java-0.14/src/main/cpp/posix.cpp:73:18: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
int retval = chmod(pathStr, mode);
data/libnative-platform-java-0.14/src/main/cpp/posix.cpp:260:14: [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.
retval = readlink(pathStr, contents, link_info.st_size);
data/libnative-platform-java-0.14/src/main/cpp/posix.cpp:192:9: [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(childPath+pathLen+1, entry.d_name);
data/libnative-platform-java-0.14/src/main/cpp/win.cpp:217:13: [4] (format) swprintf:
Potential format string problem (CWE-134). Make format string constant.
swprintf(devPath, 7, L"\\\\.\\%s", cur);
data/libnative-platform-java-0.14/src/main/cpp/win.cpp:256:21: [4] (format) swprintf:
Potential format string problem (CWE-134). Make format string constant.
swprintf(fileSystemName, MAX_PATH+1, L"cdrom");
data/libnative-platform-java-0.14/src/main/cpp/win.cpp:258:21: [4] (format) swprintf:
Potential format string problem (CWE-134). Make format string constant.
swprintf(fileSystemName, MAX_PATH+1, L"unknown");
data/libnative-platform-java-0.14/src/curses/cpp/curses.cpp:98:26: [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.
char* termType = getenv("TERM");

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.
char* valueStr = getenv(varStr);
data/libnative-platform-java-0.14/src/main/cpp/freebsd_kevents.cpp:46:20: [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).
int event_fd = open(pathStr, O_EVTONLY);

int event_fd = open(pathStr, O_RDONLY);
data/libnative-platform-java-0.14/src/main/cpp/linux.cpp:41:5: [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 buf[1024];

functions that limit length, or ensure that the size is larger than the
maximum possible length.

data/libnative-platform-java-0.14/src/main/cpp/posix.cpp:167:20: [1] (buffer) strlen:

data/libnative-platform-java-0.14/src/main/cpp/posix.cpp:190:9: [1] (buffer) strncpy:
