Summary
The deref_parseCtrl function in servers/slapd/overlays/deref.c in OpenLDAP 2.4.13 through 2.4.40 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via an empty attribute list in a deref control in a search request.
Vulnerable Configurations
Nessus
NASL family MacOS X Local Security Checks NASL id MACOS_HT210788.NASL description The remote host is running a version of macOS / Mac OS X that is 10.13.x prior to 10.13.6 Security Update 2019-007, 10.14.x prior to 10.14.6 Security Update 2019-002, or 10.15.x prior to 10.15.2. It is, therefore, affected by multiple vulnerabilities : - slapd in OpenLDAP before 2.4.30 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via an LDAP search query with attrsOnly set to true, which causes empty attributes to be returned. (CVE-2012-1164) - libraries/libldap/tls_m.c in OpenLDAP, possibly 2.4.31 and earlier, when using the Mozilla NSS backend, always uses the default cipher suite even when TLSCipherSuite is set, which might cause OpenLDAP to use weaker ciphers than intended and make it easier for remote attackers to obtain sensitive information. (CVE-2012-2668) - The rwm overlay in OpenLDAP 2.4.23, 2.4.36, and earlier does not properly count references, which allows remote attackers to cause a denial of service (slapd crash) by unbinding immediately after a search request, which triggers rwm_conn_destroy to free the session context while it is being used by rwm_op_search. (CVE-2013-4449) - The deref_parseCtrl function in servers/slapd/overlays/deref.c in OpenLDAP 2.4.13 through 2.4.40 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via an empty attribute list in a deref control in a search request. (CVE-2015-1545) - tcpdump before 4.9.3 has a heap-based buffer over-read related to aoe_print in print-aoe.c and lookup_emem in addrtoname.c. (CVE-2017-16808) - tcpdump before 4.9.3 mishandles the printing of SMB data (issue 1 of 2). (CVE-2018-10103) - tcpdump before 4.9.3 mishandles the printing of SMB data (issue 2 of 2). (CVE-2018-10105) - The LDP parser in tcpdump before 4.9.3 has a buffer over-read in print-ldp.c:ldp_tlv_print(). (CVE-2018-14461) - The ICMP parser in tcpdump before 4.9.3 has a buffer over-read in print-icmp.c:icmp_print(). (CVE-2018-14462) - The VRRP parser in tcpdump before 4.9.3 has a buffer over-read in print-vrrp.c:vrrp_print(). (CVE-2018-14463) - The LMP parser in tcpdump before 4.9.3 has a buffer over-read in print-lmp.c:lmp_print_data_link_subobjs(). (CVE-2018-14464) - The RSVP parser in tcpdump before 4.9.3 has a buffer over-read in print-rsvp.c:rsvp_obj_print(). (CVE-2018-14465) - The Rx parser in tcpdump before 4.9.3 has a buffer over- read in print-rx.c:rx_cache_find() and rx_cache_insert(). (CVE-2018-14466) - The BGP parser in tcpdump before 4.9.3 has a buffer over-read in print-bgp.c:bgp_capabilities_print() (BGP_CAPCODE_MP). (CVE-2018-14467) - The FRF.16 parser in tcpdump before 4.9.3 has a buffer over-read in print-fr.c:mfr_print(). (CVE-2018-14468) - The IKEv1 parser in tcpdump before 4.9.3 has a buffer over-read in print-isakmp.c:ikev1_n_print(). (CVE-2018-14469) - The Babel parser in tcpdump before 4.9.3 has a buffer over-read in print-babel.c:babel_print_v2(). (CVE-2018-14470) - The command-line argument parser in tcpdump before 4.9.3 has a buffer overflow in tcpdump.c:get_next_file(). (CVE-2018-14879) - The OSPFv3 parser in tcpdump before 4.9.3 has a buffer over-read in print-ospf6.c:ospf6_print_lshdr(). (CVE-2018-14880) - The BGP parser in tcpdump before 4.9.3 has a buffer over-read in print-bgp.c:bgp_capabilities_print() (BGP_CAPCODE_RESTART). (CVE-2018-14881) - The ICMPv6 parser in tcpdump before 4.9.3 has a buffer over-read in print-icmp6.c. (CVE-2018-14882) - The IEEE 802.11 parser in tcpdump before 4.9.3 has a buffer over-read in print-802_11.c for the Mesh Flags subfield. (CVE-2018-16227) - The HNCP parser in tcpdump before 4.9.3 has a buffer over-read in print-hncp.c:print_prefix(). (CVE-2018-16228) - The DCCP parser in tcpdump before 4.9.3 has a buffer over-read in print-dccp.c:dccp_print_option(). (CVE-2018-16229) - The BGP parser in tcpdump before 4.9.3 has a buffer over-read in print-bgp.c:bgp_attr_print() (MP_REACH_NLRI). (CVE-2018-16230) - The BGP parser in tcpdump before 4.9.3 allows stack consumption in print-bgp.c:bgp_attr_print() because of unlimited recursion. (CVE-2018-16300) - libpcap before 1.9.1, as used in tcpdump before 4.9.3, has a buffer overflow and/or over-read because of errors in pcapng reading. (CVE-2018-16301) - The SMB parser in tcpdump before 4.9.3 has buffer over- reads in print-smb.c:print_trans() for \MAILSLOT\BROWSE and \PIPE\LANMAN. (CVE-2018-16451) - The SMB parser in tcpdump before 4.9.3 has stack exhaustion in smbutil.c:smb_fdata() via recursion. (CVE-2018-16452) - An issue was discovered in the server in OpenLDAP before 2.4.48. When the server administrator delegates rootDN (database admin) privileges for certain databases but wants to maintain isolation (e.g., for multi-tenant deployments), slapd does not properly stop a rootDN from requesting authorization as an identity from another database during a SASL bind or with a proxyAuthz (RFC 4370) control. (It is not a common configuration to deploy a system where the server administrator and a DB administrator enjoy different levels of trust.) (CVE-2019-13057) - An issue was discovered in OpenLDAP 2.x before 2.4.48. When using SASL authentication and session encryption, and relying on the SASL security layers in slapd access controls, it is possible to obtain access that would otherwise be denied via a simple bind for any identity covered in those ACLs. After the first SASL bind is completed, the sasl_ssf value is retained for all new non-SASL connections. Depending on the ACL configuration, this can affect different types of operations (searches, modifications, etc.). In other words, a successful authorization step completed by one user affects the authorization requirement for a different user. (CVE-2019-13565) - rpcapd/daemon.c in libpcap before 1.9.1 mishandles certain length values because of reuse of a variable. This may open up an attack vector involving extra data at the end of a request. (CVE-2019-15161) - rpcapd/daemon.c in libpcap before 1.9.1 on non-Windows platforms provides details about why authentication failed, which might make it easier for attackers to enumerate valid usernames. (CVE-2019-15162) - rpcapd/daemon.c in libpcap before 1.9.1 allows attackers to cause a denial of service (NULL pointer dereference and daemon crash) if a crypt() call fails. (CVE-2019-15163) - rpcapd/daemon.c in libpcap before 1.9.1 allows SSRF because a URL may be provided as a capture source. (CVE-2019-15164) - sf-pcapng.c in libpcap before 1.9.1 does not properly validate the PHB header length before allocating memory. (CVE-2019-15165) - lmp_print_data_link_subobjs() in print-lmp.c in tcpdump before 4.9.3 lacks certain bounds checks. (CVE-2019-15166) - In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.

CVE-2013-4449 Michael Vishchers from Seven Principles AG discovered a denial of service vulnerability in slapd, the directory server implementation. When the server is configured to used the RWM overlay, an attacker can make it crash by unbinding just after connecting, because of an issue with reference counting. CVE-2014-9713 The default Debian configuration of the directory database allows every users to edit their own attributes. When LDAP directories are used for access control, and this is done using user attributes, an authenticated user can leverage this to gain access to unauthorized resources. .

| statement | Note that the deref overlay is not enabled by default, so this vulnerability only affects sites that have explicitly configured their servers to load and enable the overlay. Since this overlay has never been documented, there are no sites outside of the OpenLDAP developer community with a legitimate reason to enable this module. |
