NONE Summary
The nss_parse_ciphers function in libraries/libldap/tls_m.c in OpenLDAP does not properly parse OpenSSL-style multi-keyword mode cipher strings, which might cause a weaker than intended cipher to be used and allow remote attackers to have unspecified impact via unknown vectors.

NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2015-2131.NASL description From Red Hat Security Advisory 2015:2131 : Updated openldap packages that fix one security issue, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 7. Red Hat Product Security 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 packages contain configuration files, libraries, and documentation for OpenLDAP. A flaw was found in the way OpenLDAP parsed OpenSSL-style cipher strings. As a result, OpenLDAP could potentially use ciphers that were not intended to be enabled. (CVE-2015-3276) This issue was discovered by Martin Poole of the Red Hat Software Maintenance Engineering group. The openldap packages have been upgraded to upstream version 2.4.40, which provides a number of bug fixes and one enhancement over the previous version : * The ORDERING matching rules have been added to the ppolicy attribute type descriptions. * The server no longer terminates unexpectedly when processing SRV records. * Missing objectClass information has been added, which enables the user to modify the front-end configuration by standard means. (BZ#1147982) This update also fixes the following bugs : * 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#1125152) * The httpd service sometimes terminated unexpectedly with a segmentation fault on the libldap library unload. The underlying source code has been modified to prevent a bad memory access error that caused the bug to occur. As a result, httpd no longer crashes in this situation. (BZ#1158005) * After upgrading the system from Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 7, symbolic links to certain libraries unexpectedly pointed to locations belonging to the openldap-devel package.

Red Hat Product Security 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 packages contain configuration files, libraries, and documentation for OpenLDAP. A flaw was found in the way OpenLDAP parsed OpenSSL-style cipher strings. As a result, OpenLDAP could potentially use ciphers that were not intended to be enabled. (CVE-2015-3276) This issue was discovered by Martin Poole of the Red Hat Software Maintenance Engineering group. The openldap packages have been upgraded to upstream version 2.4.40, which provides a number of bug fixes and one enhancement over the previous version : * The ORDERING matching rules have been added to the ppolicy attribute type descriptions. * The server no longer terminates unexpectedly when processing SRV records. * Missing objectClass information has been added, which enables the user to modify the front-end configuration by standard means. (BZ#1147982) This update also fixes the following bugs : * 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#1125152) * The httpd service sometimes terminated unexpectedly with a segmentation fault on the libldap library unload. The underlying source code has been modified to prevent a bad memory access error that caused the bug to occur. As a result, httpd no longer crashes in this situation. (BZ#1158005) * After upgrading the system from Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 7, symbolic links to certain libraries unexpectedly pointed to locations belonging to the openldap-devel package. If the user uninstalled openldap-devel, the symbolic links were broken and the last seen 2020-06-01 modified 2020-06-02 plugin id 86970 published 2015-11-20 reporter This script is Copyright (C) 2015-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/86970 title RHEL 7 : openldap (RHSA-2015:2131) NASL family Fedora Local Security Checks NASL id FEDORA_2017-CEB1B8659E.NASL description This update should make OpenLDAP up to date with latest NSS, notably : - fix olcTLSProtocolMin handling - fix TLS_CIPHER_SUITE parsing - update a list of ciphers to fit latest NSS development - make use of NSS global settings for `DEFAULTS last seen 2020-06-05 modified 2017-02-03 plugin id 96968 published 2017-02-03 reporter This script is Copyright (C) 2017-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/96968 title Fedora 25 : openldap (2017-ceb1b8659e)
