22 This is a *heads-up* notice about the upcoming release.
23 You may plan your availability and schedule an update of the Exim
24 packages supplied by your distribution or build the new release from the
25 source, once the release goes public on CRD.
30 We discovered a vulnerability. We consider the risk of an exploit as
31 low, you need to have a fairly unusual runtime configuration. Neither
32 our default runtime configuration nor the runtime configuration shipped
33 by the Debian distribution is vulnerable.
35 The vulnerability is exploitable either remotely or locally and could
36 be used to execute other programs with root privilege.
