Summary: Updated Red Hat Directory Server and related packages that fix three security issues are now available for Red Hat Directory Server 8.2. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Directory Server 8 (for RHEL 5 Server) - i386, x86_64 Red Hat Directory Server 8.0 (for AS v. 4) - i386, x86_64 Red Hat Directory Server 8.0 (for ES v. 4) - i386, x86_64 3. Description: Red Hat Directory Server is an LDAPv3-compliant directory server. The redhat-ds-base package includes the LDAP server and command line utilities for server administration. A flaw was found in the way Red Hat Directory Server handled simple paged result searches. If an unauthenticated user were able to send multiple simple paged search requests to Directory Server, it could cause the server to crash. (CVE-2011-0019) When multiple Red Hat Directory Server instances were configured on the system to run under different unprivileged users, the Directory Server setup scripts set insecure permissions on the /var/run/dirsrv/ directory, which stores process ID (pid) files. A local user could use this flaw to manipulate the pid files in that directory, possibly preventing Directory Server instances from starting correctly, or causing the Directory Server init script to kill an arbitrary process when shutting down Directory Server. (CVE-2011-0022) It was found that multiple scripts shipped with Red Hat Directory Server set the LD_LIBRARY_PATH environment variable to an insecure value containing an empty path. A local user able to trick a user running those scripts (usually the root user) to run them while working from an attacker-writable directory could use this flaw to escalate their privileges via a specially-crafted dynamic library. (CVE-2011-0532) All Red Hat Directory Server users should upgrade to these updated packages, which correct these issues. After installing the updated packages, the dirsrv daemon must be restarted ("service dirsrv restart") for the update to take effect. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5.
