Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.04 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in OpenLDAP.

Software Description: - openldap: OpenLDAP utilities

Details:

Denis Andzakovic discovered that OpenLDAP incorrectly handled certain BER data. A remote attacker could possibly use this issue to cause OpenLDAP to crash, resulting in a denial of service. (CVE-2015-6908)

Dietrich Clauss discovered that the OpenLDAP package incorrectly shipped with a potentially unsafe default access control configuration. Depending on how the database is configure, this may allow users to impersonate others by modifying attributes such as their Unix user and group numbers. (CVE-2014-9713)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 15.04:
slapd 2.4.31-1+nmu2ubuntu12.3

Ubuntu 14.04 LTS:
slapd 2.4.31-1+nmu2ubuntu8.2

Ubuntu 12.04 LTS:
slapd 2.4.28-1.1ubuntu4.6

In general, a standard system update will make all the necessary changes.

For existing installations, access rules that begin with "to *" need to be manually adjusted to remove any instances of "by self write".
