RHBA-2012:1389 - Bug Fix Advisory

Topic

Updated mod_authz_ldap packages that fix three bugs are now available for Red
Hat Enterprise Linux 6.

Description

The mod_authz_ldap packages provide a module for the Apache HTTP Server to
authenticate users against an LDAP database.

This update fixes the following bugs:

• Prior to this update, the License field of the mod_authz_ldap packages

contained an incorrect tag. This update modifies the license text. Now, the
license tag correctly reads "ASL1.0". (BZ#607797)

• Prior to this update, the mod_authz_ldap module could leak memory. As a

consequence, the memory consumption of the httpd process could increase as more
requests were processed. This update modifies the underlying code to handle
LDAP correctly. Now, the memory consumption as at expected levels.(BZ#643691)

• Prior to this update, passwords were logged in plain text to the error log

when an LDAP bind password was configured if a connection error occurred. This
update modifies the underlying code to prevent passwords from being logged in
error conditions. (BZ#782442)

All users of mod_authz_ldap are advised to upgrade to this updated package,
which fixes these bugs.
