RHBA-2011:1613 - Bug Fix Advisory

Topic

Updated libpciaccess, xorg-x11-font-utils, xorg-x11-util-macros,
xorg-x11-proto-devel and libdrm packages that fix several bugs and add various
enhancements are now available for Red Hat Enterprise Linux 6.

Description

These X.Org support packages are part of the platform necessary to run the
latest X.Org server and drivers.

The libpciaccess library provides portable PCI access routines across multiple
operating systems.

The Direct Rendering Manager runtime library (libdrm) provides a user-space
interface library for direct rendering clients.

The xorg-x11-font-utils package provides X.Org X11 font utilities required for
font installation, conversion and generation.

The xorg-x11-util-macros package provides X.Org X11 autotools macros required
for building various packages that comprise the X Window System.

The xorg-x11-proto-devel package provides X.Org X11 Protocol headers.

The following packages have been upgraded to the higher upstream versions, which
provide a number of bug fixes and enhancements over the previous versions:

• The libpciaccess package has been upgraded to upstream version 0.12.1.

(BZ#713771)

• The libdrm package has been upgraded to upstream version 2.4.25. (BZ#713770)
• The xorg-x11-font-utils package has been upgraded to upstream version 7.2.

(BZ#717022)

• The xorg-x11-util-macros package has been upgraded to upstream version 1.14.0.

(BZ#713846)

• The xorg-x11-proto-devel package package has been upgraded to upstream version

7.6. (BZ#713845)

In addition, this update fixes the following bug:

• The file permissions were set incorrectly for certain device nodes, such as

the /dev/dri/controlD64 file. This problem could have been misused for DoS
(Denial of Service) attacks against the current console users if the users were
running X Windows. With this update, the file permissions are now set more
strictly for these device nodes. (BZ#747965)

All users of libpciaccess, xorg-x11-font-utils, xorg-x11-util-macros,
xorg-x11-proto-devel and libdrm are advised to upgrade to these updated
packages, which fix these bugs and add these enhancements.
