"This update for amavisd-new fixes the following issues :

wmavisd-new was updated to version 2.11.1 (bsc#1123389) :

removed a trailing dot element from @INC, as a workaround for a perl
vulnerability CVE-2016-1238 (bsc#987887)

amavis-services: bumping up syslog level from LOG_NOTICE to LOG_ERR
for a message 'PID <pid> went away', and removed redundant newlines
from some log messages </pid>

safe_decode() and safe_decode_utf8(): avoid warning messages 'Use of
uninitialized value in subroutine entry' in Encode::MIME::Header when
the $check argument is undefined

@sa_userconf_maps has been extended to allow loading of per-recipient
(or per-policy bank, or global) SpamAssassin configuration set from
LDAP. For consistency with SQL a @sa_userconf_maps entry prefixed with
'ldap:' will load SpamAssassin configuration set using the
load_scoreonly_ldap() method; a patch by Atanas Karashenski

add some Sanesecurity.Foxhole false positives to the default list
@virus_name_to_spam_score_maps

updated some comments

Update amavis-milter to version 2.6.1: Fixed bug when creating
amavisd-new policy bank names

description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
