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)

  - 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-2019-15903)
