USN-152-1: PAM/NSS LDAP vulnerabilitiy

Ubuntu Security Notice USN-152-1

21st July, 2005

openldap2, libpam-ldap, libnss-ldap vulnerabilities

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

  • Ubuntu 5.04
  • Ubuntu 4.10

Details

Andrea Barisani discovered a flaw in the SSL handling of pam-ldap and
libnss-ldap. When a client connected to a slave LDAP server using SSL,
the slave server did not use SSL as well when contacting the LDAP
master server. This caused passwords and other confident information
to be transmitted unencrypted between the slave and the master.

Update instructions

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

Ubuntu 5.04:
libpam-ldap
libnss-ldap
slapd
Ubuntu 4.10:
libpam-ldap
libnss-ldap
slapd

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
