DESCRIPTION:
Multiple vulnerabilities have been reported in Red Hat Directory
Server, which can be exploited by malicious, local users to cause a
DoS (Denial of Service) and gain escalated privileges and by
malicious people to cause a DoS (Denial of Service).

1) An error when handling simple paged search requests can be
exploited to cause the server to crash via multiple search requests.

2) An error in certain setup scripts due to setting insecure
permissions on the "/var/run/dirsrv/" directory containing process ID
files can be exploited to manipulate the PID files resulting in e.g.
preventing the server from starting or killing an arbitrary process
when the server shuts down.

Successful exploitation of this vulnerability requires multiple
server instances to be configured to run under different unprivileged
users.

3) An error due to certain scripts incorrectly setting the
environment variable LD_LIBRARY_PATH to contain an empty path can be
exploited to gain escalated privileges by e.g. tricking a user into
running the script in a directory containing a malicious library.

SOLUTION:
Updated packages are available via Red Hat Network.
