15 Synopsis
16 ========
17
18 A flaw in OpenLDAP allows remote unauthenticated attackers to cause a
19 Denial of Service.
20
21 Background
22 ==========
23
24 OpenLDAP Software is an open source implementation of the Lightweight
25 Directory Access Protocol.
26
27 Affected packages
28 =================
29
30 -------------------------------------------------------------------
31 Package / Vulnerable / Unaffected
32 -------------------------------------------------------------------
33 1 net-nds/openldap < 2.3.43 >= 2.3.43
34
35 Description
36 ===========
37
38 Cameron Hotchkies discovered an error within the parsing of ASN.1 BER
39 encoded packets in the "ber_get_next()" function in
40 libraries/liblber/io.c.
41
42 Impact
43 ======
44
45 A remote unauthenticated attacker can send a specially crafted ASN.1
46 BER encoded packet which will trigger the error and cause an
47 "assert()", terminating the "slapd" daemon.
48
49 Workaround
50 ==========
51
52 There is no known workaround at this time.
53
54 Resolution
55 ==========
56
57 All OpenLDAP users should upgrade to the latest version:
58
59 # emerge --sync
60 # emerge --ask --oneshot --verbose ">=net-nds/openldap-2.3.43"
