CID 11049: Readlink used insecurely (READLINK)Passing size argument "4096UL" implies readlink() can return up to "4096UL" bytes.
Assigning: "numread" = readlink().
 135    numread = readlink(symlink_name, target, PATH_MAX);
At conditional (1): "numread < 0L" taking the false branch.

 138        DEBUG(2, ("readlink failed [%d]: %s\n", ret, strerror(ret)));
 139        return ret;
 140    }
"target[numread]" is essentially buffer[sizeof(buffer)] which is an off-by-one error.
 141    target[numread] = '\0';
