-----------------
permissions on /dev/null. Exempt it from some checks.
Reported by Andreas M. Kirchwitz.
+PP/03 Report version information for many libraries, including
+ Exim version information for dynamically loaded libraries. Created
+ version.h, now support a version extension string for distributors
+ who patch heavily. Dynamic module ABI change.
+
+PP/04 CVE-2011-0017 - check return value of setuid/setgid. This is a
+ privilege escalation vulnerability whereby the Exim run-time user
+ can cause root to append content of the attacker's choosing to
+ arbitrary files.
+
+PP/05 Bugzilla 1041: merged DCC maintainer's fixes for return code.
+ (Wolfgang Breyha)
+
+PP/06 Bugzilla 1071: fix delivery logging with untrusted macros.
+ If dropping privileges for untrusted macros, we disabled normal logging
+ on the basis that it would fail; for the Exim run-time user, this is not
+ the case, and it resulted in successful deliveries going unlogged.
+ Fixed. Reported by Andreas Metzler.
