USN-305-1: OpenLDAP vulnerability

27 June 2006

openldap2, openldap2.2 vulnerability

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

  • Ubuntu 6.06 LTS
  • Ubuntu 5.10
  • Ubuntu 5.04

Software Description


When processing overly long host names in OpenLDAP’s slurpd replication server, a buffer overflow caused slurpd to crash.

If an attacker manages to inject a specially crafted host name into slurpd, this might also be exploited to execute arbitrary code with slurpd’s privileges; however, since slurpd is usually set up to replicate only trusted machines, this should not be exploitable in normal cases.

Update instructions

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

Ubuntu 6.06 LTS
slapd - 2.2.26-5ubuntu2.1
Ubuntu 5.10
slapd - 2.2.26-3ubuntu0.1
Ubuntu 5.04
slapd - 2.1.30-3ubuntu3.2

To update your system, please follow these instructions:

In general, a standard system upgrade is sufficient to effect the necessary changes.
