Low

Why this priority?

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.

From the Ubuntu Security Team

It was discovery that sendmail has a vulnerability where it disclosure sensitive informations via a carfted message. An attacker could use it to retrieve it.
