PARTIAL Summary
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.

NASL family CentOS Local Security Checks NASL id CENTOS_RHSA-2014-0126.NASL description Updated openldap packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. OpenLDAP is an open source suite of Lightweight Directory Access Protocol (LDAP) applications and development tools. LDAP is a set of protocols used to access and maintain distributed directory information services over an IP network. The openldap package contains configuration files, libraries, and documentation for OpenLDAP. A denial of service flaw was found in the way the OpenLDAP server daemon (slapd) performed reference counting when using the rwm (rewrite/remap) overlay. A remote attacker able to query the OpenLDAP server could use this flaw to crash the server by immediately unbinding from the server after sending a search request. (CVE-2013-4449) Red Hat would like to thank Michael Vishchers from Seven Principles AG for reporting this issue. This update also fixes the following bug : * Previously, OpenLDAP did not properly handle a number of simultaneous updates. As a consequence, sending a number of parallel update requests to the server could cause a deadlock. With this update, a superfluous locking mechanism causing the deadlock has been removed, thus fixing the bug. (BZ#1056124) All openldap users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. last seen 2020-06-01 modified 2020-06-02 plugin id 72267 published 2014-02-04 reporter This script is Copyright (C) 2014-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/72267 title CentOS 6 : openldap (CESA-2014:0126) code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Red Hat Security Advisory RHSA-2014:0126 and # CentOS Errata and Security Advisory 2014:0126 respectively. # include("compat.inc"); if (description) { script_id(72267); script_version("1.11"); script_cvs_date("Date: 2020/01/06"); script_cve_id("CVE-2013-4449"); script_bugtraq_id(63190); script_xref(name:"RHSA", value:"2014:0126"); script_name(english:"CentOS 6 : openldap (CESA-2014:0126)"); script_summary(english:"Checks rpm output for the updated packages"); script_set_attribute( attribute:"synopsis", value:"The remote CentOS host is missing one or more security updates." ); script_set_attribute( attribute:"description", value: "Updated openldap packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 6.

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-2018-14464) - 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.
