Ubuntu 4.10 / 5.04 : openldap2, libpam-ldap, libnss-ldap vulnerabilities (USN-152-1)

Medium Nessus Plugin ID 20553


The remote Ubuntu host is missing one or more security-related patches.


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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected packages.
