Ubuntu Security Notice USN-305-1
27th 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
Details
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 version:
- 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: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system upgrade is sufficient to effect the
necessary changes.
