<title>Multiple Vulnerabilities in ssmtp</title>
|
|
<synopsis>
|
|
There are multiple format string vulnerabilities in the SSMTP package,
|
|
which may allow an attacker to run arbitrary code with ssmtp's privileges
|
|
(potentially root).

|
SSMTP is a very simple mail transfer agent (MTA) that relays mail from the
|
|
local machine to another SMTP host. It is not designed to function as a
|
|
full mail server; its sole purpose is to relay mail.

|
<p>
|
|
There are two format string vulnerabilities inside the log_event() and
|
|
die() functions of ssmtp. Strings from outside ssmtp are passed to various
|
|
printf()-like functions from within log_event() and die() as format
|
|
strings. An attacker could cause a specially-crafted string to be passed to
|
|
these functions, and potentially cause ssmtp to execute arbitrary code.

|
<impact type="high">
|
|
<p>
|
|
If ssmtp connects to a malicious mail relay server, this vulnerability can
|
|
be used to execute code with the rights of the mail sender, including root.
|

|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time. All users are advised to upgrade
|
|
to the latest available version of ssmtp.
