Patch_SG0002693_Release_Note This release note describes patch SG0002693 to IRIX 5.3. Patch SG0002693 replaces patches SG0000518, SG0000650, SG0000965, SG0001211, SG0002025, and SG0002155. 1.1 Supported_Hardware_Platforms This patch contains bug fixes for all platforms. 1.2 Supported_Software_Platforms This patch contains bug fixes for the X11 Execution Environment (1021572033) on a system running IRIX 5.3. The software cannot be installed on other configurations. 1.3 Bugs_Fixed_by_Patch_SG0002693 This patch contains fixes for the following bugs in IRIX 5.3. Patch SG0002693 also includes the bug fixes from patches SG0000650, SG0000965 and SG0002155. Bug numbers from Silicon Graphics bug tracking system are included for reference. o Bug #530669: Buffer overflow in Xrm code. o Bug #530672: Buffer overflow in Xt default error handler. o Bug #543320: Buffer overflow in X library font name parsing. o Bug #544859: Patch SG0002155 breaks Desktop -> Customize -> Windows options. 1.4 Bugs_Fixed_by_Patch_SG0002155 Patch SG0002693 also includes the bug fixes from Patch SG00002155. o Bug #439052: XCreateIC leaks meomry. o Bug #463094: Some keypad keys activate the wrong text widget translations when NumLock is enabled. This only happens when the user is using a keyboard mapping with four keysyms per keycode (common with European keyboards). - 2 - o Bug #488823: Applications which generate signals such as SIGARLM may lose connection to IM server. o Bug #493564: Security vulnerability in libXt. o Bug #495591: Buffer overflow allows unprivileged users to get root access through setuid X programs. o Bug #496885: Buffer overflows possible in libX11 internationalization code. o Bug #518036: Potential buffer overflow in XGetErrorDatabaseText. 1.5 Bugs_Fixed_by_Patch_SG00001211 Patch SG0002693 also includes the bug fixes from Patch SG00001211. o Bug #273287: password expiration (e.g. passwd -f username or password aging) was not honored by xdm. o Bug #266334: X authority does not work if there is a dot in the hostname because uname is used to get the hostname instead of gethostname. o Bug #273251: There is a bug in xdm that causes X terminals to fail to start a session correctly.

It's also possible that the hook could do something to cause protocol to be enqueued. This change corrects a deficiency in handling either of those cases. o Bug #286066: SgGraphWidget core dumped in XtDispatchEventToWindow. o Bug #289889: This bug is specific to the R6 Intrinsics library. It is exercised only when X extension event handlers are registered by a client of Xt. Without - 3 - this fix, extension event handling, which was a leading feature of the R6 library, is not reliable. 1.7 Bugs_Fixed_by_Patch_SG0000650 Patch SG0002693 also includes the bug fixes from Patch SG0000650. o Bug #277446: The window to widget hash table in libXt could get corrupted in certain cases causing programs to crash. 1.8 Subsystems_Included_in_Patch_SG0002693 This patch release includes these subsystems: o patchSG0002693.x_dev_sw.dev o patchSG0002693.x_eoe_sw.eoe 1.9 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. 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. - 4 - 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 1.10 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 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. 1.11 Known_Problems
