| Detailed Description |
According to its banner, the version of Samba 3.x running on the remote host is earlier than 3.3.15 / 3.4.12 / 3.5.7. An error exists in the range checks on file descriptors in the 'FD_SET' macro which allows stack corruption. This corruption can cause Samba to crash or to continually try selecting on an improper descriptor set.
An attacker who is able to get a connection to a file share, either authenticated or via a guest connection, can leverage this issue to launch a denial of service attack against the affected smbd service.
* Note: If this check solely relied on the version number of the remote Samba server to assess this vulnerability, then this might be a false positive.
