Scientific Linux SL4 CVE-2006-5158 Important Denial of Service Kernel Update

Important: kernel security update. Date: Wed, 27 Jun 2007 15:27:22 -0500 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 update Issue date: 2007-06-25 CVE Names: CVE-2006-5158 CVE-2006-7203 CVE-2007-0773 CVE-2007-0958 CVE-2007-1353 CVE-2007-2172 CVE-2007-2525 CVE-2007-2876 CVE-2007-3104 These new kernel packages contain fixes for the security issues described below: * a flaw in the connection tracking support for SCTP that allowed a remote user to cause a denial of service by dereferencing a NULL pointer. (CVE-2007-2876, Important) * a flaw in the mount handling routine for 64-bit systems that allowed a local user to cause denial of service (crash). (CVE-2006-7203, Important) * a flaw in the IPv4 forwarding base that allowed a local user to cause an out-of-bounds access. (CVE-2007-2172, Important) * a flaw in the PPP over Ethernet implementation that allowed a local user to cause a denial of service (memory consumption) by creating a socket using connect and then releasing it before the PPPIOCGCHAN ioctl has been called. (CVE-2007-2525, Important) * a flaw in the fput ioctl handling of 32-bit applications running on 64-bit platforms that allowed a local user to cause a denial of service (panic). (CVE-2007-0773, Important) * a flaw in the NFS locking daemon that allowed a local user to cause denial of service (deadlock). (CVE-2006-5158, Moderate) * a flaw in the sysfs_readdir function that allowed a local user to cause a denial of service by dereferencing a NULL pointer. (CVE-2007-3104, Moderate) * a flaw in the core-dump handling that allowed a local user to create core dumps from unreadable binaries via PT_INTERP. (CVE-2007-0958, Low) * a flaw in the Bluetooth subsystem that allowed a local user to trigger an information leak. (CVE-2007-1353, Low) In addition, the following bugs were addressed: * the NFS couldrecurse on the same spinlock. Also, NFS, under certain conditions, did not completely clean up Posix locks on a file close, leading to mount failures. * the 32bit compatibility didn't return to userspace correct values for the rt_sigtimedwait system call. * the count for unused inodes could be incorrect at times, resulting in dirty data not being written to disk in a timely manner. * the cciss driver had an incorrect disk size calculation (off-by-one error) which prevented disk dumps. NOTE1: From The Upstream Vendors release notes "During PCI probing, Red Hat Enterprise Linux 4 Update 5 attempts to use information obtained from MCFG (memory-mapped PCI configuration space). On AMD-systems, this type of access does not work on some buses, as the kernel cannot parse the MCFG table. To work around this, add the parameter pci=conf1 or pci=nommconf on the kernel boot line in /etc/grub.conf. For example: title Red Hat Enterprise Linux AS (2.6.9-42.0.2.EL) root (hd0,0) kernel /vmlinuz-2.6.9-42.0.2.EL ro root=/dev/VolGroup00/LogVol00 rhgb quiet pci=conf1 initrd /initrd-2.6.9-42.0.2.EL.img Doing this instructs the kernel to use PCI Conf1 access instead of MCFG-based access." NOTE2: From The Upstream Vendors Knowledge Base "Why did the ordering of my NIC devices change in Red Hat Enterprise Linux 4.5? The 2.6.9-55 version of the Red Hat Enterprise Linux 4 kernel (Update 5) reverts to the 2.4 ordering of network interface cards (NICs) on certain systems. Note that if the "HWADDR=MAC ADDRESS" line is present in the /etc/sysconfig/network-scripts/ifcfg-ethX files, the NIC ordering will not change. To restore the original 2.6 ordering, which is different from the 2.4 ordering, boot with the option pci=nobfsort " SL 4.x SRPMS: kernel-2.6.9-55.0.2.EL.src.rpm i386: kernel-2.6.9-55.0.2.EL.i686.rpm kernel-devel-2.6.9-55.0.2.EL.i686.rpm kernel-doc-2.6.9-55.0.2.EL.noarch.rpm kernel-hugemem-2.6.9-55.0.2.EL.i686.rpm kernel-hugemem-devel-2.6.9-55.0.2.EL.i686.rpm kernel-smp-2.6.9-55.0.2.EL.i686.rpm kernel-smp-devel-2.6.9-55.0.2.EL.i686.rpm kernel-xenU-2.6.9-55.0.2.EL.i686.rpm kernel-xenU-devel-2.6.9-55.0.2.EL.i686.rpm Dependancies: kernel-module-fuse-2.6.9-55.0.2.EL-2.5.3-1.SL.i686.rpm kernel-module-fuse-2.6.9-55.0.2.ELhugemem-2.5.3-1.SL.i686.rpm kernel-module-fuse-2.6.9-55.0.2.ELsmp-2.5.3-1.SL.i686.rpm kernel-module-fuse-2.6.9-55.0.2.ELxenU-2.5.3-1.SL.i686.rpm kernel-module-ipw3945-2.6.9-55.0.2.EL-1.1.0-1.SL4.i686.rpm kernel-module-ipw3945-2.6.9-55.0.2.ELhugemem-1.1.0-1.SL4.i686.rpm kernel-module-ipw3945-2.6.9-55.0.2.ELsmp-1.1.0-1.SL4.i686.rpm kernel-module-ipw3945-2.6.9-55.0.2.ELxenU-1.1.0-1.SL4.i686.rpm kernel-module-madwifi-2.6.9-55.0.2.EL-0.9.3.1-10.sl4.i686.rpm kernel-module-madwifi-2.6.9-55.0.2.ELhugemem-0.9.3.1-10.sl4.i686.rpm kernel-module-madwifi-2.6.9-55.0.2.ELsmp-0.9.3.1-10.sl4.i686.rpm kernel-module-madwifi-hal-2.6.9-55.0.2.EL-0.9.3.1-10.sl4.i686.rpm kernel-module-madwifi-hal-2.6.9-55.0.2.ELhugemem-0.9.3.1-10.sl4.i686.rpm kernel-module-madwifi-hal-2.6.9-55.0.2.ELsmp-0.9.3.1-10.sl4.i686.rpm kernel-module-ndiswrapper-2.6.9-55.0.2.EL-1.41-1.SL.i686.rpm kernel-module-ndiswrapper-2.6.9-55.0.2.ELhugemem-1.41-1.SL.i686.rpm kernel-module-ndiswrapper-2.6.9-55.0.2.ELsmp-1.41-1.SL.i686.rpm kernel-module-ndiswrapper-2.6.9-55.0.2.ELxenU-1.41-1.SL.i686.rpm kernel-module-openafs-2.6.9-55.0.2.EL-1.4.4-46.SL4.i686.rpm kernel-module-openafs-2.6.9-55.0.2.ELhugemem-1.4.4-46.SL4.i686.rpm kernel-module-openafs-2.6.9-55.0.2.ELsmp-1.4.4-46.SL4.i686.rpm kernel-module-openafs-2.6.9-55.0.2.ELxenU-1.4.4-46.SL4.i686.rpm kernel-module-r1000-2.6.9-55.0.2.EL-2.2-2.SL4x.i686.rpm kernel-module-r1000-2.6.9-55.0.2.ELhugemem-2.2-2.SL4x.i686.rpm kernel-module-r1000-2.6.9-55.0.2.ELsmp-2.2-2.SL4x.i686.rpm kernel-module-r1000-2.6.9-55.0.2.ELxenU-2.2-2.SL4x.i686.rpm x86_64: kernel-2.6.9-55.0.2.EL.x86_64.rpm kernel-devel-2.6.9-55.0.2.EL.x86_64.rpm kernel-doc-2.6.9-55.0.2.EL.noarch.rpm kernel-largesmp-2.6.9-55.0.2.EL.x86_64.rpm kernel-largesmp-devel-2.6.9-55.0.2.EL.x86_64.rpm kernel-smp-2.6.9-55.0.2.EL.x86_64.rpm kernel-smp-devel-2.6.9-55.0.2.EL.x86_64.rpm kernel-xenU-2.6.9-55.0.2.EL.x86_64.rpm kernel-xenU-devel-2.6.9-55.0.2.EL.x86_64.rpm Dependancies: kernel-module-fuse-2.6.9-55.0.2.EL-2.5.3-1.SL.x86_64.rpm kernel-module-fuse-2.6.9-55.0.2.ELlargesmp-2.5.3-1.SL.x86_64.rpm kernel-module-fuse-2.6.9-55.0.2.ELsmp-2.5.3-1.SL.x86_64.rpm kernel-module-fuse-2.6.9-55.0.2.ELxenU-2.5.3-1.SL.x86_64.rpm kernel-module-ipw3945-2.6.9-55.0.2.EL-1.1.0-1.SL4.x86_64.rpm kernel-module-ipw3945-2.6.9-55.0.2.ELlargesmp-1.1.0-1.SL4.x86_64.rpm kernel-module-ipw3945-2.6.9-55.0.2.ELsmp-1.1.0-1.SL4.x86_64.rpm kernel-module-ipw3945-2.6.9-55.0.2.ELxenU-1.1.0-1.SL4.x86_64.rpm kernel-module-madwifi-2.6.9-55.0.2.EL-0.9.3.1-10.sl4.x86_64.rpm kernel-module-madwifi-2.6.9-55.0.2.ELlargesmp-0.9.3.1-10.sl4.x86_64.rpm kernel-module-madwifi-2.6.9-55.0.2.ELsmp-0.9.3.1-10.sl4.x86_64.rpm kernel-module-madwifi-hal-2.6.9-55.0.2.EL-0.9.3.1-10.sl4.x86_64.rpm kernel-module-madwifi-hal-2.6.9-55.0.2.ELlargesmp-0.9.3.1-10.sl4.x86_64.rpm kernel-module-madwifi-hal-2.6.9-55.0.2.ELsmp-0.9.3.1-10.sl4.x86_64.rpm kernel-module-ndiswrapper-2.6.9-55.0.2.EL-1.41-1.SL.x86_64.rpm kernel-module-ndiswrapper-2.6.9-55.0.2.ELlargesmp-1.41-1.SL.x86_64.rpm kernel-module-ndiswrapper-2.6.9-55.0.2.ELsmp-1.41-1.SL.x86_64.rpm kernel-module-ndiswrapper-2.6.9-55.0.2.ELxenU-1.41-1.SL.x86_64.rpm kernel-module-openafs-2.6.9-55.0.2.EL-1.4.4-46.SL4.x86_64.rpm kernel-module-openafs-2.6.9-55.0.2.ELlargesmp-1.4.4-46.SL4.x86_64.rpm kernel-module-openafs-2.6.9-55.0.2.ELsmp-1.4.4-46.SL4.x86_64.rpm kernel-module-openafs-2.6.9-55.0.2.ELxenU-1.4.4-46.SL4.x86_64.rpm kernel-module-r1000-2.6.9-55.0.2.EL-2.2-2.SL4x.x86_64.rpm kernel-module-r1000-2.6.9-55.0.2.ELlargesmp-2.2-2.SL4x.x86_64.rpm kernel-module-r1000-2.6.9-55.0.2.ELsmp-2.2-2.SL4x.x86_64.rpm kernel-module-r1000-2.6.9-55.0.2.ELxenU-2.2-2.SL4x.x86_64.rpm The upstream vendor has not released the GFS src.rpm yet.

Red Hat Linux 7.1 and 7.2: RHSA-2002:028-13 Critical Kernel IRC Issue

The Linux Netfilter team has found a problem in the "IRC connectiontracking" component of the firewall within the linux kernel. This problemaffects Red Hat Linux versions 7.1 and 7.2.. ` -------------------------------------------------------------------- Red Hat, Inc. Red Hat Security Advisory Synopsis: Updated 2.4 kernel available Advisory ID: RHSA-2002:028-13 Issue date: 2002-02-13 Updated on: 2002-02-27 Product: Red Hat Linux Keywords: irc connection tracking netfilter lcall Cross references: Obsoletes: RHSA-2002:007 --------------------------------------------------------------------- 1. Topic: The Linux Netfilter team has found a problem in the "IRC connection tracking" component of the firewall within the linux kernel. This problem affects Red Hat Linux versions 7.1 and 7.2. 2. Relevant releases/architectures: Red Hat Linux 7.1 - alpha, athlon, i386, i586, i686, ia64 Red Hat Linux 7.2 - athlon, i386, i586, i686, ia64, s390 3. Problem description: The Linux Netfilter team has found a problem in the IRC connection tracking component of the firewall within the linux kernel. This component is distributed with kernels in Red Hat Linux 7.1 and 7.2, although it is not used in default installations. The problem consists of an excessively broad netmask setting which is applied to check if an "IRC DCC" connection through a masquerading firewall should be allowed. This results in unwanted ports being opened on the firewall, which could, depending on the firewall filter ruleset, allow inbound connections. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2002-0060 to this issue. Thanks to Jozsef Kadlecsik and Harald Welte of the netfilter team. Users are advised to upgrade to this errata kernel containing patches which fix these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. Red Hat Linux 7.1 usersshould update the packages in the XFree86 Erratum (RHEA-2002:010). The procedure for upgrading the kernel is documented at: Support Please read the directions for your architecture carefully before proceeding with the kernel upgrade. Please note that this update is also available via Red Hat Network. Many people find this to be an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. Note that you need to select the kernel explicitly on default configurations of up2date.
