1.84.1. RHBA-2009:1271: bug fix and enhancement update

An ia32el update that features a new release of ia32el, adds support for SSE4.2 instructions, and fixes
several bugs is now available.
The ia32el package contains the IA-32 Execution Layer platform, which allows emulation of IA-32
binaries on Intel Itanium processors.
This updated package fixes the following bugs:
• if SELinux is in Enforcing mode, the 'allow_unconfined_execmem_dyntrans', 'allow_execmem'
and 'allow_execstack' booleans must be enabled in order for the IA-32 Execution Layer (i.e. the
ia32el service) to operate correctly. If only the 'allow_execmem' or 'allow_execstack' booleans
are enabled, the ia32el service can still support emulation; however, SELinux might issue an AVC
denial to the service. In previous releases, whenever SELinux issued an AVC denial to ia32el, users
were not informed that these booleans needed to be enabled first. This release provides proper
documentation (in the README file) for this requirement, and revises the init script to warn the user
if any of these boolean requirements are not met at runtime.
• this update also fixes a bug that caused the fcntl system call to fail whenever the 'flock' structure
was filled with values exceeding 2GB.
With this update, the IA-32 Execution Layer is now at version V7:
• this adds support for the latest system calls and SSE4.2 instructions. In addition, this update
also applies several fixes from upstream to improve performance, compatibility, and robustness.

Users of the IA-32 Execution Layer should upgrade to this update.

Updated icu packages that fix a security issue are now available for Red Hat Enterprise Linux 5.
This update has been rated as having moderate security impact by the Red Hat Security Response
Team.
The International Components for Unicode (ICU) library provides robust and full-featured Unicode
services.
A flaw was found in the way ICU processed certain, invalid byte sequences during Unicode
conversion. If an application used ICU to decode malformed, multibyte character data, it may have
