The remote VMware ESX host is missing a security-related patch. It is, therefore, affected by multiple vulnerabilities, including arbitrary code execution vulnerabilities, in several third-party components and libraries :

  - glibc
  - glibc-common
  - nscd
  - openldap
  - sudo

Using the Codenomicon LDAPv3 test suite, Ilkka Mattila and Tuomas Salomaki discovered that the slap_modrdn2mods function in modrdn.c in OpenLDAP does not check the return value from a call to the smr_normalize function. A remote attacker could use specially crafted modrdn requests to crash the slapd daemon or possibly execute arbitrary code. (CVE-2010-0211)

Using the Codenomicon LDAPv3 test suite, Ilkka Mattila and Tuomas Salomaki discovered that OpenLDAP does not properly handle empty RDN strings. A remote attacker could use specially crafted modrdn requests to crash the slapd daemon. (CVE-2010-0212)

In the default installation under Ubuntu 8.04 LTS and later, attackers would be isolated by the OpenLDAP AppArmor profile for the slapd daemon.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several issues have been fixed in OpenLDAP :

  - specially crafted MODRDN operations can crash the     OpenLDAP server. (CVE-2010-0211 / CVE-2010-0212)

  - syncrepl might loose deletes in refreshAndPersist mode

  - DoS when handling 0-bytes

Updated openldap packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

OpenLDAP is an open source suite of LDAP (Lightweight Directory Access Protocol) applications and development tools.

Multiple flaws were discovered in the way the slapd daemon handled modify relative distinguished name (modrdn) requests. An authenticated user with privileges to perform modrdn operations could use these flaws to crash the slapd daemon via specially crafted modrdn requests.
(CVE-2010-0211, CVE-2010-0212)

Red Hat would like to thank CERT-FI for responsibly reporting these flaws, who credit Ilkka Mattila and Tuomas Salomaki for the discovery of the issues.

Users of OpenLDAP should upgrade to these updated packages, which contain a backported patch to correct these issues. After installing this update, the OpenLDAP daemons will be restarted automatically.

This update fixes two denial of service bugs in the openldap server while handling MODRDN operations. (CVE-2010-0211 and CVE-2010-0212)

Multiple vulnerabilities has been discovered and corrected in openldap :

The slap_modrdn2mods function in modrdn.c in OpenLDAP 2.4.22 does not check the return value of a call to the smr_normalize function, which allows remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a modrdn call with an RDN string containing invalid UTF-8 sequences, which triggers a free of an invalid, uninitialized pointer in the slap_mods_free function, as demonstrated using the Codenomicon LDAPv3 test suite (CVE-2010-0211).

OpenLDAP 2.4.22 allows remote attackers to cause a denial of service (crash) via a modrdn call with a zero-length RDN destination string, which is not properly handled by the smr_normalize function and triggers a NULL pointer dereference in the IA5StringNormalize function in schema_init.c, as demonstrated using the Codenomicon LDAPv3 test suite (CVE-2010-0212).

Packages for 2008.0 and 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:

  - specially crafted MODRDN operations can crash the     OpenLDAP server. (CVE-2010-0211 / CVE-2010-0212)

  - syncrepl might loose deletes in refreshAndPersist mode

a. Service Console update for glibc

   The service console packages glibc, glibc-common, and nscd are each    updated to version 2.5-34.4908.vmw.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the names CVE-2010-3847 and CVE-2010-3856 to the issues    addressed in this update.

b. Service Console update for sudo

   The service console package sudo is updated to version    1.7.2p1-8.el5_5.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the name CVE-2010-2956 to the issue addressed in this    update.

c. Service Console update for openldap

   The service console package openldap is updated to version    2.3.43-12.el5_5.1.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the names CVE-2010-0211 and CVE-2010-0212 to the issues    addressed in this update.

Updated openldap packages that fix two security issues are now available for Red Hat Enterprise Linux 4.

OpenLDAP is an open source suite of LDAP (Lightweight Directory Access Protocol) applications and development tools.

An uninitialized pointer use flaw was discovered in the way the slapd daemon handled modify relative distinguished name (modrdn) requests.
An authenticated user with privileges to perform modrdn operations could use this flaw to crash the slapd daemon via specially crafted modrdn requests. (CVE-2010-0211)

Red Hat would like to thank CERT-FI for responsibly reporting the CVE-2010-0211 flaw, who credit Ilkka Mattila and Tuomas Salomaki for the discovery of the issue.

A flaw was found in the way OpenLDAP handled NUL characters in the CommonName field of X.509 certificates. An attacker able to get a carefully-crafted certificate signed by a trusted Certificate Authority could trick applications using OpenLDAP libraries into accepting it by mistake, allowing the attacker to perform a man-in-the-middle attack. (CVE-2009-3767)

Users of OpenLDAP should upgrade to these updated packages, which contain backported patches to resolve these issues. After installing this update, the OpenLDAP daemons will be restarted automatically.

Two remote vulnerabilities have been discovered in OpenLDAP. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2010-0211     The slap_modrdn2mods function in modrdn.c in OpenLDAP     2.4.22 does not check the return value of a call to the     smr_normalize function, which allows remote attackers to     cause a denial of service (segmentation fault) and     possibly execute arbitrary code via a modrdn call with     an RDN string containing invalid UTF-8 sequences.

  - CVE-2010-0212     OpenLDAP 2.4.22 allows remote attackers to cause a     denial of service (crash) via a modrdn call with a     zero-length RDN destination string.

- fixed regression caused by tls accept patch

    - updated autofs schema

    - openldap built with conectionless support
