Hello,
I am afraid that my first message wasn't clear. Not from first look at
least. Sorry about that. Let me elaborate, I think it is probably a
security bug. makesocketpath() checks !S_ISDIR(sb.st_mode); when true it
returns with error. But then it checks !S_ISDIR(sb.st_mode) in second
time and it is definitely false at this point:
if (sb.st_uid != uid || (!S_ISDIR(sb.st_mode) &&
sb.st_mode & (S_IRWXG|S_IRWXO)) != 0) {
errno = EACCES;
return (NULL);
}
Being false it effectively disables the permission check. Hence, for
example, world-writable directory will pass.
