VID 18116
Severity 20
Port 25
Protocol TCP
Class SMTP
Detailed Description The remote mail server is running a version of Sendmail prior to 8.14.9. It is, therefore, affected by a flaw related to file descriptors and the 'close-on-exec' flag that may allow a local attacker to cause unspecified impact on open SMTP connections.

- CVE-2014-3956
The sm_close_on_exec function in conf.c in sendmail before 8.14.9 has arguments in the wrong order, and consequently skips setting expected FD_CLOEXEC flags, which allows local users to access unintended high-numbered file descriptors via a custom mail-delivery program.
