SECURITY: [RHSA-2000:012] New openldap packages available
-----BEGIN PGP SIGNED MESSAGE----- - --------------------------------------------------------------------- Red Hat, Inc. Security Advisory Synopsis: New openldap packages. Advisory ID: RHSA-2000:012-05 Issue date: 2000-04-13 Updated on: 2000-04-21 Product: Red Hat Linux Keywords: openldap startup symlink overwrite denial Cross references: N/A - --------------------------------------------------------------------- 1. Topic: New openldap packages are available which fix a security vulnerability in Red Hat Linux 6.1 and 6.2. 2. Relevant releases/architectures: Red Hat Linux 6.1 - i386 alpha sparc Red Hat Linux 6.2 - i386 alpha sparc 3. Problem description: OpenLDAP follows symbolic links when creating files. The default location for these files is /usr/tmp, which is a symlink to /tmp, which in turn is a world-writable directory. Local users can destroy the contents of any file on any mounted filesystem. 4. Solution: For each RPM for your particular architecture, run: rpm -Fvh [filename] where filename is the name of the RPM. Administrators with existing databases should also move their NEXTID and *.dbb files from /usr/tmp to /var/lib/ldap, and verify that the ''directory'' setting in /etc/openldap/slapd.conf is changed accordingly. 5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 10714 - Insecure file creation using static files which follow symlinks. 6. Obsoleted by: N/A 7. Conflicts with: N/A 8.
