FINAL RESULTS:
data/hexxagon-1.0pl1/src/gui/gtkboardlist.cpp:59:24: [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.
return std::string(getenv("HOME")) + "/.hexxagon";
data/hexxagon-1.0pl1/src/libhexx/game.cpp:270:2: [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 str[64];
data/hexxagon-1.0pl1/src/libhexx/game.cpp:283:2: [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 str[64];
data/hexxagon-1.0pl1/src/gui/gtkhexxagonboardplay.cpp:140:9: [1] (obsolete) usleep:
This C routine is considered obsolete (as opposed to the shell command by
the same name). The interaction of this function with SIGALRM and other
timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead.
usleep(10000);
data/hexxagon-1.0pl1/src/libhexx/game.cpp:271:5: [1] (buffer) read:
Check buffer boundaries if used in a loop including recursive loops
(CWE-120, CWE-20).
in.read(str, strlen(FILE_HDR_V1));
data/hexxagon-1.0pl1/src/libhexx/game.cpp:271:15: [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).
in.read(str, strlen(FILE_HDR_V1));
data/hexxagon-1.0pl1/src/libhexx/game.cpp:273:31: [1] (buffer) strlen:
