Ubuntu 6.06 LTS / 8.04 LTS / 9.04 / 9.10 / 10.04 LTS : openldap, openldap2.2, openldap2.3 vulnerabilities (USN-965-1)

medium Nessus Plugin ID 48282

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

Solution

Update the affected packages.
