"According to the version of the sendmail packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerability :
- The Sendmail program is a very widely used Mail
Transport Agent (MTA).MTAs send mail from one machine
to another. Sendmail is not a client program, which you
use to read your email. Sendmail is a behind-the-scenes
program which actually moves your email over networks
or the Internet to where you want it to go.If you ever
need to reconfigure Sendmail, you will also need to
have the sendmail-cf package installed. If you need
documentation on Sendmail, you can install the
sendmail-doc package.Security Fix(es):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.(CVE-2014-3956)
Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
