USN-305-1: OpenLDAP vulnerability

27 June 2006

OpenLDAP vulnerability



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

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