Vulnerability Assessment Details

[GLSA-200404-18] Multiple Vulnerabilities in ssmtp

Vulnerability Assessment Summary
Multiple Vulnerabilities in ssmtp

Detailed Explanation for this Vulnerability Assessment
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. A possible hacker 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.
