Details
It was discovered that Exim incorrectly handled memory in the ESMTP
CHUNKING extension. A remote attacker could use this issue to cause Exim to
crash, resulting in a denial of service, or possibly execute arbitrary
code. The default compiler options for affected releases should reduce the
vulnerability to a denial of service.
