ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.

Ubuntu 11.10 USN-1533-1 Critical: Linux Kernel Access Issue

Several security issues were fixed in the kernel.. =========================================================================Ubuntu Security Notice USN-1533-1 August 10, 2012 linux vulnerabilities ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 11.10 Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: An error was discovered in the Linux kernel's network TUN/TAP device implementation. A local user with access to the TUN/TAP interface (which is not available to unprivileged users until granted by a root user) could exploit this flaw to crash the system or potential gain administrative privileges. (CVE-2012-2136) Ulrich Obergfell discovered an error in the Linux kernel's memory management subsystem on 32 bit PAE systems with more than 4GB of memory installed. A local unprivileged user could exploit this flaw to crash the system. (CVE-2012-2373) A flaw was discovered in the Linux kernel's epoll system call. An unprivileged local user could use this flaw to crash the system. (CVE-2012-3375) Some errors where discovered in the Linux kernel's UDF file system, which is used to mount some CD-ROMs and DVDs. An unprivileged local user could use these flaws to crash the system. (CVE-2012-3400) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: linux-image-3.0.0-24-generic 3.0.0-24.40 linux-image-3.0.0-24-generic-pae 3.0.0-24.40 linux-image-3.0.0-24-omap 3.0.0-24.40 linux-image-3.0.0-24-powerpc 3.0.0-24.40 linux-image-3.0.0-24-powerpc-smp 3.0.0-24.40 linux-image-3.0.0-24-powerpc64-smp 3.0.0-24.40 linux-image-3.0.0-24-server 3.0.0-24.40 linux-image-3.0.0-24-virtual 3.0.0-24.40 After a standard system update you need to reboot your computer to make all the necessary changes.

Red Hat Enterprise Linux 6: RHSA-2011-1088 Moderate: Security Issues

Updated systemtap packages that fix two security issues are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores,. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: systemtap security update Advisory ID: RHSA-2011:1088-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2011:1088.html Issue date: 2011-07-25 CVE Names: CVE-2011-2502 CVE-2011-2503 ==================================================================== 1. Summary: Updated systemtap packages that fix two security issues are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: SystemTap is an instrumentation system for systems running the Linux kernel. The system allows developers to write scripts to collect data on the operation of the system. It was found that SystemTap did not perform proper module path sanity checking if a user specified a custom path to the uprobes module, used whenperforming user-space probing ("staprun -u"). A local user who is a member of the stapusr group could use this flaw to bypass intended module-loading restrictions, allowing them to escalate their privileges by loading an arbitrary, unsigned module. (CVE-2011-2502) A race condition flaw was found in the way the staprun utility performed module loading. A local user who is a member of the stapusr group could use this flaw to modify a signed module while it is being loaded, allowing them to escalate their privileges. (CVE-2011-2503) SystemTap users should upgrade to these updated packages, which contain backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network.

Scientific Linux SL4.x: CVE-2007-4130 Important Kernel Update

Important: kernel security and bug fix update. Date: Fri, 1 Feb 2008 15:52:55 -0600 Reply-To: Troy Dawson Sender: Security Errata for Scientific Linux From: Troy Dawson Subject: Security ERRATA for kernel on SL4.x i386/x86_64 Comments: To: "This email address is being protected from spambots. You need JavaScript enabled to view it." Synopsis: Important: kernel security and bug fix update Issue date: 2008-01-31 CVE Names: CVE-2007-4130 CVE-2007-5500 CVE-2007-6063 CVE-2007-6151 CVE-2007-6206 CVE-2007-6694 CVE-2008-0001 These updated kernel packages fix the following security issues: A flaw was found in the virtual filesystem (VFS). A local unprivileged user could truncate directories to which they had write permission; this could render the contents of the directory inaccessible. (CVE-2008-0001, Important) A flaw was found in the implementation of ptrace. A local unprivileged user could trigger this flaw and possibly cause a denial of service (system hang). (CVE-2007-5500, Important) A flaw was found in the way the Red Hat Enterprise Linux 4 kernel handled page faults when a CPU used the NUMA method for accessing memory on Itanium architectures. A local unprivileged user could trigger this flaw and cause a denial of service (system panic). (CVE-2007-4130, Important) A possible NULL pointer dereference was found in the chrp_show_cpuinfo function when using the PowerPC architecture. This may have allowed a local unprivileged user to cause a denial of service (crash). (CVE-2007-6694, Moderate) A flaw was found in the way core dump files were created. If a local user can get a root-owned process to dump a core file into a directory, which the user has write access to, they could gain read access to that core file. This could potentially grant unauthorized access to sensitive information. (CVE-2007-6206, Moderate) Two buffer overflow flaws were found in the Linux kernel ISDN subsystem. A local unprivileged user could use these flaws to cause a denial of service.
