This security problem can allow local users to get write access to directories that they are otherwise not able to write to. Red Hat would like to thank the members of the BUGTRAQ mailing list, the members of the Linux Security Audit team, and others. All users of Red Hat Linux are encouraged to upgrade to the new packages immediately. As always, these packages have been signed with the Red Hat PGP key. INSTALLATION INSTRUCTIONS: - -------------------------- X Windows is a large and complex package, so the upgrade procedure is somewhat more lengthy and involved than for other packages. Please make sure you carefully follow the instructions pertaining to your particular release and platform of Red Hat Linux. Red Hat Linux 5.x: - ------------------ In some circumstances, you may be required to add --force and/or --nodeps to the rpm command line options to insure a proper upgrade. Add these options if the command line given gives an error. Intel: All updates can be found at ftp://updates.redhat.com/5.2/i386. 1. Upgrade your X server. The package you need is dependent on which video card you have. Get the server which matches your card. 2. Upgrade your X libraries and base install: rpm -Uvh ftp://updates.redhat.com/5.2/i386/XFree86-libs-3.3.3.1-1.1.i386.rpm rpm -Uvh ftp://updates.redhat.com/5.2/i386/XFree86-3.3.3.1-1.1.i386.rpm 3. Optionally, upgrade the additional X packages, such as fonts, devel, etc. Alpha: - ------ All updates can be found at ftp://updates.redhat.com/5.2/alpha. 1. Upgrade your X server. The package you need is dependent on which video card you have. Get the server which matches your card. 2. Upgrade your X libraries and base install: rpm -Uvh ftp://updates.redhat.com/5.2/alpha/XFree86-libs-3.3.3.1-1.1.alpha.rpm rpm -Uvh ftp://updates.redhat.com/5.2/alpha/XFree86-3.3.3.1-1.1.alpha.rpm 3. Optionally, upgrade the additional X packages, such as fonts, devel, etc. SPARC: - ------ All updates can be found at ftp://updates.redhat.com/5.2/sparc. 1. Upgrade your X server. The package you need is dependent on which frame buffer your SPARC has. Get the server which matches your card. 2. Upgrade your X libraries and base install: rpm -Uvh ftp://updates.redhat.com/5.2/sparc/XFree86-libs-3.3.3.1-1.1.sparc.rpm rpm -Uvh ftp://updates.redhat.com/5.2/sparc/XFree86-3.3.3.1-1.1.sparc.rpm 3. Optionally, upgrade the additional X packages, such as fonts, devel, etc. 4. If a link named /etc/X11/X does not exist, pointing at the proper X server that you use (for instance, /usr/X11R6/bin/Xsun), create it now. Red Hat Linux 4.2: - ------------------ In some circumstances, you may be required to add --force and/or --nodeps to the rpm command line options to insure a proper upgrade. Add these options if the command line given gives an error. Intel: - ------ All updates can be found at ftp://updates.redhat.com/4.2/i386. 1. Make sure that you are running RPM 2.5.3 or later before proceeding. Upgrade as follows: rpm -Uvh ftp://updates.redhat.com/4.2/i386/rpm-2.5.3-4.2.i386.rpm 2. Make sure you have the latest Xconfigurator installed: rpm -Uvh ftp://updates.redhat.com/4.2/i386/Xconfigurator-2.6.1-1.i386.rpm 3. Upgrade your X server. The package you need is dependent on which video card you have. Get the server which matches your card. 4. Upgrade your X libraries and base install: rpm -Uvh ftp://updates.redhat.com/4.2/i386/XFree86-libs-3.3.3.1-0.1.i386.rpm rpm -Uvh ftp://updates.redhat.com/4.2/i386/XFree86-3.3.3.1-0.1.i386.rpm 5. Optionally, upgrade the additional X packages, such as fonts, devel, etc. Alpha: - ------ All updates can be found at ftp://updates.redhat.com/4.2/alpha. 1. Make sure that you are running RPM 2.5.3 or later before proceeding. Upgrade as follows: rpm -Uvh ftp://updates.redhat.com/4.2/alpha/rpm-2.5.3-4.2.alpha.rpm 2. Make sure you have the latest Xconfigurator installed: rpm -Uvh ftp://updates.redhat.com/4.2/alpha/Xconfigurator-2.6.1-1.alpha.rpm 3. Upgrade your X server. The package you need is dependent on which video card you have. Get the server which matches your card. 4. Upgrade your X libraries and base install: rpm -Uvh ftp://updates.redhat.com/4.2/alpha/XFree86-libs-3.3.3.1-0.1.alpha.rpm rpm -Uvh ftp://updates.redhat.com/4.2/alpha/XFree86-3.3.3.1-0.1.alpha.rpm 5. Optionally, upgrade the additional X packages, such as fonts, devel, etc. SPARC: - ------ All updates can be found at ftp://updates.redhat.com/4.2/sparc. The X environment which shipped with Red Hat 4.2 SPARC was different than that for other architectures. X was placed in the directory /usr/X11R6.1, whereas every other architecture expected it to reside under /usr/X11R6. This errata release corrects the situation. As you upgrade the packages, YOU WILL SEE ERRORS FROM RPM about missing files, but they can safely be ignored. The following instructions will work for an unmodified Red Hat 4.2 SPARC environment. 1. Make sure that you are running RPM 2.5.3 or later before proceeding. Upgrade as follows: rpm -Uvh ftp://updates.redhat.com/4.2/sparc/rpm-2.5.3-4.2.sparc.rpm 2. Remove the symbolic link /usr/X11R6: rm /usr/X11R6 3. Move the directory /usr/X11R6.1 to /usr/X11R6: mv /usr/X11R6.1 /usr/X11R6 4. Upgrade the server package for the type of SPARC framebuffer you have. This is system dependent. 5. Upgrade your X libraries and base install: rpm -Uvh ftp://updates.redhat.com/4.2/sparc/XFree86-libs-3.3.3.1-0.1.sparc.rpm rpm -Uvh ftp://updates.redhat.com/4.2/sparc/XFree86-3.3.3.1-0.1.sparc.rpm 6. Optionally, upgrade the additional X packages, such as fonts, devel, etc. 7. Make a symbolic link from /usr/X11R6 to /usr/X11R6.1 for backwards compatibility: cd /usr; ln -s X11R6 X11R6.1 8. If a link named /etc/X11/X does not exist, pointing at the proper X server that you use (for instance, /usr/X11R6/bin/Xsun), create it now.
