<description>
|
|
|
|
|
|
<p>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.
