FINAL RESULTS:
data/kcov-38+dfsg/src/engines/system-mode-binary-lib.cc:43:11: [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.
int rv = readlink("/proc/self/exe", buf, sizeof(buf));
data/kcov-38+dfsg/src/engines/system-mode-engine.cc:134:8: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
if (chmod(dst.c_str(), st.st_mode) < 0)
data/kcov-38+dfsg/src/main.cc:443:6: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
if (chmod(library.c_str(), 0755) < 0)
data/kcov-38+dfsg/src/engines/bash-engine.cc:210:8: [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.
if (execv(vec[0], vec))
data/kcov-38+dfsg/src/engines/bash-engine.cc:482:8: [4] (shell) popen:
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.
fp = popen(cmd.c_str(), "r");
data/kcov-38+dfsg/src/engines/bash-engine.cc:520:3: [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(envString, val.c_str());
data/kcov-38+dfsg/src/engines/clang-coverage-engine.cc:51:4: [4] (shell) execv:

(CWE-78). try using a library call that implements the same functionality
if available.
execv(argv[0], argv);
data/kcov-38+dfsg/src/engines/gcov-engine.cc:44:4: [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(argv[0], argv);
data/kcov-38+dfsg/src/engines/ptrace.cc:100:7: [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.

a constant for the format specification.
