Patch_SG0004663_Release_Note This release note describes patch SG0004663 to IRIX 6.5.16. This patch does not replace other patches. 1.1 Supported_Hardware_Platforms This patch contains bug fixes for all configurations supported in Irix 6.5. The software cannot be installed on other configurations. 1.2 Supported_Software_Platforms This patch contains bug fixes for the X Window System X11R6.6 (version 1287689520) on systems running IRIX 6.5.16. Only the maintenance stream is the target for this patch. The features stream is fixed by patch 4664. The software cannot be installed on other configurations. 1.3 Bugs_Fixed_by_Patch_SG0004663 This patch contains fixes for the following bugs in IRIX 6.5.16: 849315 850186 850899 853472 860810 Bug numbers from Silicon Graphics bug tracking system are included for reference. Patch 4663 Fixes: Bug #849315- Cannot use X input method in 64-bit mode X input method does not work for applications that are compiled in 64-bit mode. An empty string was returned, because _XRead() could not handle different data sizes. This problem appeared when using worldview in Korean or Chinese. The current patch will provide a propper behavior to solve this problem. Bug #850186- zlib has a security vulnerability on X11 There was a security problem on zlib due to a "double free()" which could hit the Irix X server. A fix for this problem was released by zlib.org and incorporated into zlib 1.1.4. This patch reflects such update. Bug #850899- security issue in X MIT-SHM extension When the X server was running as root it was possible for any local user that can connect to it to read or write any SHM segment. This problem was fix in Irix - 2 - on the X's shared memory extension. That fix is incorporated into this patch. Bug #853472- GCG/SeqLab app dumps core in 64-bit X libs The application GCG Wisconsin has an X interface called SeqLab which was dumping core on startup in the 64-bit X libraries under Irix. A problem in libXt was found and corrected with this patch. Bug #860810- Mozilla DoS can crash X server This is another security issue where by trying to render a very large font, Xsgi was aborting its operation. The X fonts libraries and the X server were fix by not allowing a font rendering of more than 3K pixels. This patch does not make roll ups. 1.4 Subsystems_Included_in_Patch_SG0004663 This patch release includes these subsystems: o patchSG0004663.dev_sw.abi o patchSG0004663.dmedia_eoe_sw.lib o patchSG0004663.x_dev_sw.dev o patchSG0004663.x_dev_sw64.dev o patchSG0004663.x_eoe_sw.Server o patchSG0004663.x_eoe_sw.eoe o patchSG0004663.x_eoe_sw.xfwp o patchSG0004663.x_eoe_sw64.eoe 1.5 Installation_Instructions Because you want to install only the patches for problems you have encountered, patch software is not installed by default. After reading the descriptions of the bugs fixed in this patch (see Section 1.3), determine the patches that meet your specific needs. - 3 - If, after reading Sections 1.1 and 1.2 of these release notes, you are unsure whether your hardware and software meet the requirements for installing a particular patch, run inst. The inst program does not allow you to install patches that are incompatible with your hardware or software. Patch software is installed like any other Silicon Graphics software product. Follow the instructions in your Software Installation Administrator's Guide to bring up the miniroot form of the software installation tools. Follow these steps to select a patch for installation: 1. At the Inst> prompt, type install patchSGxxxxxxx where xxxxxxx is the patch number. 2. Initiate the installation sequence. Type Inst> go 3. You may find that two patches have been marked as incompatible. (The installation tools reject an installation request if an incompatibility is detected.) If this occurs, you must deselect one of the patches. Inst> keep patchSGxxxxxxx where xxxxxxx is the patch number. 4. After completing the installation process, exit the inst program by typing Inst> quit 1.6 Patch_Removal_Instructions To remove a patch, use the versions remove command as you would for any other software subsystem. The removal process reinstates the original version of software unless you have specifically removed the patch history from your system. versions remove patchSGxxxxxxx - 4 - where xxxxxxx is the patch number. To keep a patch but increase your disk space, use the versions removehist command to remove the patch history. versions removehist patchSGxxxxxxx where xxxxxxx is the patch number. 1.7 Known_Problems None
