Package        : 389-ds-base
Version        : 1.3.3.5-4+deb8u4
CVE ID         : CVE-2018-14648

It was discovered that 389-ds-base (the 389 Directory Server) is vulnerable
to search queries with malformed values in the do_search() function
(servers/slapd/search.c). Attackers could leverage this vulnerability by
sending crafted queries in a loop to cause DoS.

For Debian 8 "Jessie", this problem has been fixed in version
1.3.3.5-4+deb8u4.

We recommend that you upgrade your 389-ds-base packages.

Package        : 389-ds-base

A regression was found in the recent security update for 389-ds-base
(the 389 Directory Server), announced as DLA-1554-2, caused by an
incomplete fix for CVE-2018-14648. The regression caused the server
to crash when processing requests with empty attributes.

For Debian 8 "Jessie", this problem has been fixed in version
1.3.3.5-4+deb8u5.

We recommend that you upgrade your 389-ds-base packages.
