Moderate Grub2 Administrative Access Vulnerability in Scientific Linux SL7

Moderate: grub2 security and bug fix update. Date: Mon, 21 Dec 2015 23:19:00 +0000 Reply-To: scientific-linux-users@ Sender: Security Errata for Scientific Linux From: Pat Riehecky Subject: Security ERRATA Moderate: grub2 on SL7.x x86_64 MIME-Version: 1.0 Message-ID: Synopsis: Moderate: grub2 security and bug fix update Advisory ID: SLSA-2015:2623-1 Issue Date: 2015-12-15 CVE Numbers: CVE-2015-8370 -- A flaw was found in the way the grub2 handled backspace characters entered in username and password prompts. An attacker with access to the system console could use this flaw to bypass grub2 password protection and gain administrative access to the system. (CVE-2015-8370) This update also fixes the following bug: * When upgrading from Scientific Linux 7.1 and earlier, a configured boot password was not correctly migrated to the newly introduced user.cfg configuration files. This could possibly prevent system administratorsfrom changing grub2 configuration during system boot even if they provided the correct password. This update corrects the password migration script and the incorrectly generated user.cfg file. -- SL7 x86_64 grub2-2.02-0.33.el7_2.x86_64.rpm grub2-debuginfo-2.02-0.33.el7_2.x86_64.rpm grub2-efi-2.02-0.33.el7_2.x86_64.rpm grub2-tools-2.02-0.33.el7_2.x86_64.rpm grub2-efi-modules-2.02-0.33.el7_2.x86_64.rpm - Scientific Linux Development Team .

Scientific Linux: Low Severity xorg-x11-server Security Update

Low: xorg-x11-server security and bug fix update. Date: Wed, 21 Mar 2012 16:24:51 -0500 Reply-To: This email address is being protected from spambots. You need JavaScript enabled to view it. Sender: Security Errata for Scientific Linux From: Patrick Riehecky Subject: Security ERRATA Low: xorg-x11-server on SL5.x i386/x86_64 Comments: To: This email address is being protected from spambots. You need JavaScript enabled to view it. Synopsis: Low: xorg-x11-server security and bug fix update Issue Date: 2012-02-21 CVE Numbers: CVE-2011-4028 X.Org is an open source implementation of the X Window System. It provides the basic low-level functionality that full-fledged graphical user interfaces are designed upon. A flaw was found in the way the X.Org server handled lock files. A local user with access to the system console could use this flaw to determine the existence of a file in a directory not accessible to the user, via a symbolic link attack. (CVE-2011-4028) This update also fixes the following bugs: * In rare cases, if the front and back buffer of the miDbePositionWindow() function were not both allocated in video memory, or were both allocated in system memory, the X Window System sometimes terminated unexpectedly. A patch has been provided to address this issue and X no longer crashes in the described scenario. * Previously, when the miSetShape() function called the miRegionDestroy() function with a NULL region, X terminated unexpectedly if the backing store was enabled. Now, X no longer crashes in the described scenario. * On certain workstations running in 32-bit mode, the X11 mouse cursor occasionally became stuck near the left edge of the X11 screen. A patch has been provided to address this issue and the mouse cursor no longer becomes stuck in the described scenario. * On certain workstations with a dual-head graphics adapter using the r500 driver in Zaphod mode, the mouse pointer was confined to one monitor screen and could not move to the other screen. A patch has been provided to address this issue and the mouse cursor works properly across both screens. * Due to a double free operation, Xvfb (X virtual framebuffer)terminated unexpectedly with a segmentation fault randomly when the last client disconnected, that is when the server reset. This bug has been fixed in the miDCCloseScreen() function and Xvfb no longer crashes. * Starting the Xephyr server on an AMD64 or Intel 64 architecture with an integrated graphics adapter caused the server to terminate unexpectedly. This bug has been fixed in the code and Xephyr no longer crashes in the described scenario. * Previously, when a client made a request bigger than 1/4th of the limit advertised in the BigRequestsEnable reply, the X server closed the connection unexpectedly. With this update, the maxBigRequestSize variable has been added to the code to check the size of client requests, thus fixing this bug. * When an X client running on a big-endian system called the XineramaQueryScreens() function, the X server terminated unexpectedly. This bug has been fixed in the xf86Xinerama module and the X server no longer crashes in the described scenario. * When installing Scientific Linux 5 on an IBM eServer System p blade server, the installer did not set the correct mode on the built-in KVM (Keyboard-Video-Mouse). Consequently, the graphical installer took a very long time to appear and then was displayed incorrectly. A patch has been provided to address this issue and the graphical installer now works as expected in the described scenario. Note that this fix requires the Scientific Linux 5.8 kernel update. * Lines longer than 46,340 pixels can be drawn with one of the coordinates being negative. However, for dashed lines, the miPolyBuildPoly() function overflowed the "int" type when setting up edges for a section of a dashed line. Consequently, dashed segments were not drawn at all. An upstream patch has been applied to address this issue and dashed lines are now drawn correctly. All users of xorg-x11-server are advised to upgrade to these updated packages, which correct these issues. All running X.Org server instances must be restarted for this update to take effect.
