FINAL RESULTS:
data/dzen2-0.9.5~svn271/draw.c:503:5: [4] (buffer) strcat:
Does not check for buffer overflows when concatenating to destination
[MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
snprintf (warning: strncat is easily misused).
strcat(rbuf, lbuf);
data/dzen2-0.9.5~svn271/util.c:32:2: [4] (format) vfprintf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
vfprintf(stderr, errstr, ap);
data/dzen2-0.9.5~svn271/util.c:58:4: [4] (shell) execl:
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.
execl(shell, shell, "-c", arg, (char *)NULL);
data/dzen2-0.9.5~svn271/util.c:49:25: [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.
if(!shell && !(shell = getenv("SHELL")))
data/dzen2-0.9.5~svn271/action.c:270:18: [2] (integer) atoi:
Unless checked, the resulting number can exceed the expected range
(CWE-190). If source untrusted, check both minimum and maximum, even if the
input had no minus sign (large numbers can roll over into negative number;
consider saving to an unsigned value if that is intended).
