x86_64 Architectures

Note

This flaw did not allow the attacker to acquire the contents of the SSL key. The

password has no value without the key file which arbitrary users should not have read

access to.

To better protect even this value, however, the dovecot.conf file now supports the "!include_try"

directive. The ssl_key_password option should be moved from dovecot.conf to a new file

owned by, and only readable and writable by, root (ie 0600). This file should be referenced from

dovecot.conf by setting the !include_try /path/to/password/file option.

8.2. x86_64 Architectures

• ksh has been re-based to version 2008-02-02. This update adds multi-byte character handling,

addresses many job control problems and applies several bug fixes from upstream. Note that this

update to ksh preserves compatibility for existing scripts.

8.3. s390x Architectures

• A vmconvert bug prevented it from working properly on the vmur device node (/dev/0.0.000c).

This caused vmconvert to fail when attempting to access dumps on the vmur device with the error

vmconvert: Open dump file failed! (Permission denied). An update to s390utils

in this release fixes this issue.

• The init script and config file for the mon_procd daemon and mon_fsstatd daemon were

missing from the s390utils package. Consequently these daemons could not be built and used.

The missing files have been added in this update which resolves this issue.

8.4. PowerPC Architectures

• A bug that prevented the ehci_hcd module from reloading on this architecture is now fixed. This

ensures that the Belkin 4-port PCI-Express USB Lily adapter (and other similar devices) now

function properly with Red Hat Enterprise Linux 5 when they use the ehci_hcd module.

• The libhugetlbfs library is now re-based to version 1.3. This update applies several upstream

improvements to the library, thereby improving the performance of applications that use Huge

pages.
