Description
Certain versions of Exim ship with a flawed implementation of the 'dns_build_reverse()' function which allows a local attacker to overflow a buffer and execute arbitrary code under the privileges of the mailer. As a result, a local user may be able to read the e-mail belonging to other users on the system.
