medium Nessus Plugin ID 14483

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200404-18 (Multiple Vulnerabilities in ssmtp)

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 :

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 :

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

Solution

All users are advised to upgrade to the latest available version of ssmtp.
