SciLinux: CVE-2009-3767 Moderate: openldap SL5.x i386/x86_64
Summary
carefully-crafted certificate signed by a trusted Certificate Authoritycould trick applications using OpenLDAP libraries into accepting it bymistake, allowing the attacker to perform a man-in-the-middle attack.(CVE-2009-3767)This update also fixes the following bugs:* the ldap init script did not provide a way to alter system limits forthe slapd daemon. A variable is now available in "/etc/sysconfig/ldap"for this option. (BZ#527313)* applications that use the OpenLDAP libraries to contact a MicrosoftActive Directory server could crash when a large number of networkinterfaces existed. This update implements locks in the OpenLDAP librarycode to resolve this issue. (BZ#510522)* when slapd was configured to allow client certificates, approximately90% of connections froze because of a large CA certificate file andslapd not checking the success of the SSL handshake. (BZ#509230)* the OpenLDAP server would freeze for unknown reasons under high load.These packages add support for accepting incoming connections by newthreads, resolving the issue. (BZ#507276)* the compat-openldap libraries did not list dependencies on otherlibraries, causing programs that did not specifically specify thelibraries to fail. Detection of the Application Binary Interface (ABI)in use on 64-bit systems has been added with this update. (BZ#503734)* the OpenLDAP libraries caused applications to crash due to anunprocessed network timeout. A timeval of -1 is now passed when NULL ispassed to LDAP. (BZ#495701)* slapd could crash on a server under heavy load when using rwm overlay,caused by freeing non-allocated memory during operation cleanup.(BZ#495628)* the ldap init script made a temporary script in "/tmp/" and attemptedto execute it. Problems arose when "/tmp/" was mounted with the noexecoption. The temporary script is no longer created. (BZ#483356)* the ldap init script always started slapd listening on ldap:/// evenif instructed to listen only on ldaps:///. By correcting the initscript, a user can now select which ports slapd should listen on.(BZ#481003)* the slapd manual page did not mention the supported options -V and -o.(BZ#468206)* slapd.conf had a commented-out option to load the syncprov.la module.Once un-commented, slapd crashed at start-up because the module hadalready been statically linked to OpenLDAP. This update removes"moduleload syncprov.la" from slapd.conf, which resolves this issue.(BZ#466937)* the migrate_automount.pl script produced output that was unsupportedby autofs. This is corrected by updating the output LDIF format forautomount records. (BZ#460331)* the ldap init script uses the TERM signal followed by the KILL signalwhen shutting down slapd. Minimal delay between the two signals couldcause the LDAP database to become corrupted if it had not finishedsaving its state. A delay between the signals has been added via the"STOP_DELAY" option in "/etc/sysconfig/ldap". (BZ#452064)* the migrate_passwd.pl migration script had a problem when numberfields contained only a zero. Such fields were considered to be empty,leading to the attribute not being set in the LDIF output. The conditionin dump_shadow_attributes has been corrected to allow for the attributesto contain only a zero. (BZ#113857)* the migrate_base.pl migration script did not handle third leveldomains correctly, creating a second level domain that could not be heldby a database with a three level base. This is now allowed by modifyingthe migrate_base.pl script to generate only one domain.
