Title: Exim: Arbitrary code execution
Date: July 20, 2016
Bugs: #517934, #576582
ID: 201607-12
– – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – –
Synopsis
========
A local attacker could execute arbitrary code by providing unsanitized
data to a data source or escalate privileges.
Background
==========
Exim is a message transfer agent (MTA) designed to be a a highly
configurable, drop-in replacement for sendmail.
Affected packages
=================
——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 mail-mta/exim < 4.87 >= 4.87
Description
===========
Vulnerabilities have been discovered in Exim’s implementation of
set-uid root and when using ‘perl_startup’. These vulnerabilities
require a user account on the Exim server and a configuration that does
lookups against files to which the user has edit access.
Impact
======
A local attacker could possibly execute arbitrary code with the
privileges of the process, or escalate privileges.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Exim users should upgrade to the latest version:
# emerge –sync
# emerge –ask –oneshot –verbose “>=mail-mta/exim-4.87”
