CVE-2011-3188

TITLE

Linux Kernel of IPv4 When IPv6 Service disruption in implementations ( Network failure ) Vulnerabilities

DESCRIPTION

The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service (disrupted networking) or hijack network sessions by predicting these values and sending crafted packets. ( Network failure ) May be left in a state or network sessions may be taken away. The NFSv4 implementation is one of the distributed file system protocols. (CVE-2009-4067) It was discovered that the Stream Control Transmission Protocol (SCTP) implementation incorrectly calculated lengths. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: kernel security, bug fix, and enhancement update Advisory ID: RHSA-2011:1386-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-1386.html Issue date: 2011-10-20 CVE Names: CVE-2009-4067 CVE-2011-1160 CVE-2011-1585 CVE-2011-1833 CVE-2011-2484 CVE-2011-2496 CVE-2011-2695 CVE-2011-2699 CVE-2011-2723 CVE-2011-2942 CVE-2011-3131 CVE-2011-3188 CVE-2011-3191 CVE-2011-3209 CVE-2011-3347 ===================================================================== 1. Summary: Updated kernel packages that fix multiple security issues, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having important 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 (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes: * The maximum file offset handling for ext4 file systems could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2695, Important) * IPv6 fragment identification value generation could allow a remote attacker to disrupt a target system's networking, preventing legitimate users from accessing its services. (CVE-2011-2699, Important) * A malicious CIFS (Common Internet File System) server could send a specially-crafted response to a directory read request that would result in a denial of service or privilege escalation on a system that has a CIFS share mounted. (CVE-2011-3191, Important) * A local attacker could use mount.ecryptfs_private to mount (and then access) a directory they would otherwise not have access to. Note: To correct this issue, the RHSA-2011:1241 ecryptfs-utils update must also be installed. (CVE-2011-1833, Moderate) * A flaw in the taskstats subsystem could allow a local, unprivileged user to cause excessive CPU time and memory use. (CVE-2011-2484, Moderate) * Mapping expansion handling could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2496, Moderate) * GRO (Generic Receive Offload) fields could be left in an inconsistent state. An attacker on the local network could use this flaw to cause a denial of service. GRO is enabled by default in all network drivers that support it. (CVE-2011-2723, Moderate) * RHSA-2011:1065 introduced a regression in the Ethernet bridge implementation. If a system had an interface in a bridge, and an attacker on the local network could send packets to that interface, they could cause a denial of service on that system. Xen hypervisor and KVM (Kernel-based Virtual Machine) hosts often deploy bridge interfaces. (CVE-2011-2942, Moderate) * A flaw in the Xen hypervisor IOMMU error handling implementation could allow a privileged guest user, within a guest operating system that has direct control of a PCI device, to cause performance degradation on the host and possibly cause it to hang. (CVE-2011-3131, Moderate) * IPv4 and IPv6 protocol sequence number and fragment ID generation could allow a man-in-the-middle attacker to inject packets and possibly hijack connections. Protocol sequence number and fragment IDs are now more random. (CVE-2011-3188, Moderate) * A flaw in the kernel's clock implementation could allow a local, unprivileged user to cause a denial of service. (CVE-2011-3209, Moderate) * Non-member VLAN (virtual LAN) packet handling for interfaces in promiscuous mode and also using the be2net driver could allow an attacker on the local network to cause a denial of service. (CVE-2011-3347, Moderate) * A flaw in the auerswald USB driver could allow a local, unprivileged user to cause a denial of service or escalate their privileges by inserting a specially-crafted USB device. (CVE-2009-4067, Low) * A flaw in the Trusted Platform Module (TPM) implementation could allow a local, unprivileged user to leak information to user space. (CVE-2011-1160, Low) * A local, unprivileged user could possibly mount a CIFS share that requires authentication without knowing the correct password if the mount was already mounted by another local user. (CVE-2011-1585, Low) Red Hat would like to thank Fernando Gont for reporting CVE-2011-2699; Darren Lavender for reporting CVE-2011-3191; the Ubuntu Security Team for reporting CVE-2011-1833; Vasiliy Kulikov of Openwall for reporting CVE-2011-2484; Robert Swiecki for reporting CVE-2011-2496; Brent Meshier for reporting CVE-2011-2723; Dan Kaminsky for reporting CVE-2011-3188; Yasuaki Ishimatsu for reporting CVE-2011-3209; Somnath Kotur for reporting CVE-2011-3347; Rafael Dominguez Vega for reporting CVE-2009-4067; and Peter Huewe for reporting CVE-2011-1160. The Ubuntu Security Team acknowledges Vasiliy Kulikov of Openwall and Dan Rosenberg as the original reporters of CVE-2011-1833. 4. Solution: This update also fixes several bugs and adds one enhancement. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which contain backported patches to correct these issues, and fix the bugs and add the enhancement noted in the Technical Notes. The system must be rebooted for this update to take effect. 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. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259 To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system. 5.

(CVE-2011-3191, Important) * The way fragmented IPv6 UDP datagrams over the bridge with UDP Fragmentation Offload (UFO) functionality on were handled could allow a remote attacker to cause a denial of service. (CVE-2011-3353, Moderate) * A flaw in the b43 driver. (CVE-2011-3359, Moderate) * A flaw in the way CIFS shares with DFS referrals at their root were handled could allow an attacker on the local network, who is able to deploy a malicious CIFS server, to create a CIFS network share that, when mounted, would cause the client system to crash. This update also fixes the following bugs: * Previously, a mismatch in the build-id of the kernel-rt and the one in the related debuginfo package caused failures in SystemTap and perf. (BZ#768413) * IBM x3650m3 systems were not able to boot the MRG Realtime kernel because they require a pmcraid driver that was not available. ========================================================================== Ubuntu Security Notice USN-1240-1 October 25, 2011 linux-mvl-dove vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 10.04 LTS Summary: Several security issues were fixed in the kernel. Software Description: - linux-mvl-dove: Linux kernel for DOVE Details: Ryan Sweat discovered that the kernel incorrectly handled certain VLAN packets. (CVE-2011-1576) Vasiliy Kulikov and Dan Rosenberg discovered that ecryptfs did not correctly check the origin of mount points. (CVE-2011-1833) Vasiliy Kulikov discovered that taskstats did not enforce access restrictions. A local attacker could exploit this to read certain information, leading to a loss of privacy. (CVE-2011-2494) Vasiliy Kulikov discovered that /proc/PID/io did not enforce access restrictions. A local attacker could exploit this to read certain information, leading to a loss of privacy. (CVE-2011-2495) Dan Rosenberg discovered that the Bluetooth stack incorrectly handled certain L2CAP requests. If a system was using Bluetooth, a remote attacker could send specially crafted traffic to crash the system or gain root privileges. (CVE-2011-2497) It was discovered that the EXT4 filesystem contained multiple off-by-one flaws. (CVE-2011-2695) Fernando Gont discovered that the IPv6 stack used predictable fragment identification numbers. (CVE-2011-2699) Christian Ohm discovered that the perf command looks for configuration files in the current directory. If a privileged user were tricked into running perf in a directory containing a malicious configuration file, an attacker could run arbitrary commands and possibly gain privileges. (CVE-2011-2905) Time Warns discovered that long symlinks were incorrectly handled on Be filesystems. (CVE-2011-2928) Dan Kaminsky discovered that the kernel incorrectly handled random sequence number generation. (CVE-2011-3188) Darren Lavender discovered that the CIFS client incorrectly handled certain large values. A remote attacker with a malicious server could exploit this to crash the system or possibly execute arbitrary code as the root user. (CVE-2011-3191) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 10.04 LTS: linux-image-2.6.32-219-dove 2.6.32-219.37 After a standard system update you need to reboot your computer to make all the necessary changes. 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. 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. (CVE-2011-2905) Vasiliy Kulikov discovered that the Comedi driver did not correctly clear memory. (CVE-2011-3188) Yogesh Sharma discovered that CIFS did not correctly handle UNCs that had no prefixpaths
