FINAL RESULTS:
data/lurker-2.3/common/Keys.cpp:80:3: [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(&out[0], prefix);
data/lurker-2.3/index/getdate.cpp:829:21: [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.
# define YYFPRINTF fprintf
data/lurker-2.3/index/lurker-drop-rlimit.cpp:14:2: [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[1], argv+1);
data/lurker-2.3/render/Cache.cpp:133:12: [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.
output = popen(command.c_str(), "w");
data/lurker-2.3/render/message.cpp:281:14: [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.
FILE* pgp = popen(command.c_str(), "r");
data/lurker-2.3/render/message.cpp:318:6: [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.

if available.

destination buffer is at least of size MAXPATHLEN, andto protect against
implementation problems, the input argument should also be checked to
