Detail

Problem Description:

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.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

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 Salomäki 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.

4. Solution:

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

605448 - CVE-2010-0211 openldap: modrdn processing uninitialized pointer free 605452 - CVE-2010-0212 openldap: modrdn processing IA5StringNormalize NULL pointer dereference

Title: DSA-2077-1 openldap -- several
Description: 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 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 via a modrdn call with a zero-length RDN destination string. For the stable distribution, this problem has been fixed in version 2.4.11-1+lenny2. For the unstable distribution, this problem has been fixed in version 2.4.23-1. We recommend that you upgrade your openldap packages.

Title: USN-965-1 -- openldap, openldap2.2, openldap2.3 vulnerabilities
Description: Using the Codenomicon LDAPv3 test suite, Ilkka Mattila and Tuomas Salomäki 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. Using the Codenomicon LDAPv3 test suite, Ilkka Mattila and Tuomas Salomäki discovered that OpenLDAP does not properly handle empty RDN strings. A remote attacker could use specially crafted modrdn requests to crash the slapd daemon. In the default installation under Ubuntu 8.04 LTS and later, attackers would be isolated by the OpenLDAP AppArmor profile for the slapd daemon.
