<description>
|
|
<p>Exim supports the use of multiple “-p” command line arguments
|
|
causing a memory leak. This could lead to a stack-clash in user-space and
|
|
as result the attacker can, “clash” or “smash” the stack or
|
|
another memory region, or “jump” over the stack guard-page.

</impact>
|

</workaround>
