CVE-2014-0196


TITLE

Linux Kernel of drivers/tty/n_tty.c of n_tty_write Service disruption in functions (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2014-002401

DESCRIPTION

The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the "LECHO & !OPOST" case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings. The Linux kernel is prone to a memory-corruption vulnerability. Local attackers can exploit this issue to execute arbitrary code in contexts of the application or corrupt the kernel memory. Failed exploit attempts can result in a denial-of-service condition. Linux kernel 3.0 through versions 3.14.3 are vulnerable. This BID is being retired as a duplicate of BID 67199. The NFSv4 implementation is one of the distributed file system protocols. The vulnerability is caused by the program not properly managing the access rights of the tty driver. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: kernel-rt security update Advisory ID: RHSA-2014:0557-01 Product: Red Hat Enterprise MRG for RHEL-6 Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0557.html Issue date: 2014-05-27 CVE Names: CVE-2014-0100 CVE-2014-0196 CVE-2014-1737 CVE-2014-1738 CVE-2014-2672 CVE-2014-2678 CVE-2014-2706 CVE-2014-2851 CVE-2014-3122 ===================================================================== 1. Summary: Updated kernel-rt packages that fix multiple security issues are now available for Red Hat Enterprise MRG 2.5. 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: MRG Realtime for RHEL 6 Server v.2 - noarch, x86_64 3. * A race condition leading to a use-after-free flaw was found in the way the Linux kernel's TCP/IP protocol suite implementation handled the addition of fragments to the LRU (Last-Recently Used) list under certain conditions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system by sending a large amount of specially crafted fragmented packets to that system. (CVE-2014-0100, Important) * A race condition flaw, leading to heap-based buffer overflows, was found in the way the Linux kernel's N_TTY line discipline (LDISC) implementation handled concurrent processing of echo output and TTY write operations originating from user space when the underlying TTY driver was PTY. An unprivileged, local user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-0196, Important) * A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. (CVE-2014-1737, Important) * It was found that the Linux kernel's floppy driver leaked internal kernel memory addresses to user space during the processing of the FDRAWCMD IOCTL command. A local user with write access to /dev/fdX could use this flaw to obtain information about the kernel heap arrangement. (CVE-2014-1738, Low) Note: A local user with write access to /dev/fdX could use these two flaws (CVE-2014-1737 in combination with CVE-2014-1738) to escalate their privileges on the system. * A use-after-free flaw was found in the way the ping_init_sock() function of the Linux kernel handled the group_info reference counter. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-2851, Important) * It was found that a remote attacker could use a race condition flaw in the ath_tx_aggr_sleep() function to crash the system by creating large network traffic on the system's Atheros 9k wireless network adapter. (CVE-2014-2672, Moderate) * A NULL pointer dereference flaw was found in the rds_iw_laddr_check() function in the Linux kernel's implementation of Reliable Datagram Sockets (RDS). A local, unprivileged user could use this flaw to crash the system. (CVE-2014-2678, Moderate) * A race condition flaw was found in the way the Linux kernel's mac80211 subsystem implementation handled synchronization between TX and STA wake-up code paths. A remote attacker could use this flaw to crash the system. (CVE-2014-2706, Moderate) * It was found that the try_to_unmap_cluster() function in the Linux kernel's Memory Managment subsystem did not properly handle page locking in certain cases, which could potentially trigger the BUG_ON() macro in the mlock_vma_page() function. A local, unprivileged user could use this flaw to crash the system. (CVE-2014-3122, Moderate) Red Hat would like to thank Matthew Daley for reporting CVE-2014-1737 and CVE-2014-1738. The CVE-2014-0100 issue was discovered by Nikolay Aleksandrov of Red Hat. Users are advised to upgrade to these updated packages, which upgrade the kernel-rt kernel to version kernel-rt-3.10.33-rt32.34 and correct these issues. The system must be rebooted for this update to take effect. 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. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 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-2014-1737 / CVE-2014-1738 Matthew Daley discovered that missing input sanitising in the FDRAWCMD ioctl and an information leak could result in privilege escalation. CVE-2014-2851 Incorrect reference counting in the ping_init_sock() function allows denial of service or privilege escalation. CVE-2014-3122 Incorrect locking of memory can result in local denial of service. For the stable distribution (wheezy), these problems have been fixed in version 3.2.57-3+deb7u1. This update also fixes a regression in the isci driver and suspend problems with certain AMD CPUs (introduced in the updated kernel from the Wheezy 7.5 point release). For the unstable distribution (sid), these problems will be fixed soon. 6.3) - i386, ppc64, s390x, x86_64 3. ============================================================================ Ubuntu Security Notice USN-2201-1 May 06, 2014 linux-lts-saucy vulnerability ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 LTS Summary: The system could be made to crash or run programs as an administrator. Software Description: - linux-lts-saucy: Linux hardware enablement kernel from Saucy Details: A flaw was discovered in the Linux kernel's pseudo tty (pty) device. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 LTS: linux-image-3.11.0-20-generic 3.11.0-20.35~precise1 linux-image-3.11.0-20-generic-lpae 3.11.0-20.35~precise1 After a standard system update you need to reboot your computer to make all the necessary changes. 6.2) - x86_64 3. This update also fixes the following bug: * Prior to this update, a guest-provided value was used as the head length of the socket buffer allocated on the host. If the host was under heavy memory load and the guest-provided value was too large, the allocation could have failed, resulting in stalls and packet drops in the guest's Tx path. With this update, the guest-provided value has been limited to a reasonable size so that socket buffer allocations on the host succeed regardless of the memory load on the host, and guests can send packets without experiencing packet drops or stalls.
