The encode_share_access function in fs/nfs/nfs4xdr.c in the Linux kernel before 2.6.29 allows local users to cause a denial of service (BUG and system crash) by using the mknod system call with a pathname on an NFSv4 filesystem.

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2012-251:02 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel     handles the basic functions of the operating system: memory allocation, process allocation, device input     and output, etc.
    Security issues fixes with this release:
    CVE-2011-1020     The proc filesystem implementation in the Linux kernel 2.6.37 and earlier does not restrict access to the     /proc directory tree of a process after this process performs an exec of a setuid program, which allows     local users to obtain sensitive information or cause a denial of service via open, lseek, read, and write     system calls.
    CVE-2011-4077     Buffer overflow in the xfs_readlink function in fs/xfs/xfs_vnodeops.c in XFS in the Linux kernel 2.6, when     CONFIG_XFS_DEBUG is disabled, allows local users to cause a denial of service (memory corruption and     crash) and possibly execute arbitrary code via an XFS image containing a symbolic link with a long     pathname.
    CVE-2011-4132     The cleanup_journal_tail function in the Journaling Block Device (JBD) functionality in the Linux kernel     2.6 allows local users to cause a denial of service (assertion error and kernel oops) via an ext3 or ext4     image with an invalid log first block value.
    CVE-2011-4325     The NFS implementation in Linux kernel before 2.6.31-rc6 calls certain functions without properly     initializing certain data, which allows local users to cause a denial of service (NULL pointer dereference     and O_DIRECT oops), as demonstrated using diotest4 from LTP.
    CVE-2011-4330     Stack-based buffer overflow in the hfs_mac2asc function in fs/hfs/trans.c in the Linux kernel 2.6 allows     local users to cause a denial of service (crash) and possibly execute arbitrary code via an HFS image with     a crafted len field.
    CVE-2011-3637     CVE-2011-4324     CVE-2011-4348     CVE-2011-3638     CVE-2011-4086     CVE-2011-4127     CVE-2012-0028     CVE-2012-0207     No description available at the time of writing, please refer to the CVE links below.
    Fixed bugs:
    - If an SCSI scan was initiated on a host in recovery mode, the scan failed without any error output; this     has been fixed and the SCSI layer now waits for the host to recover before starting scan operations.
    - Because SG_IO ioctls were not previously implemented correctly, sending an SG_IO ioctl request to a     virtio-blk disk caused the sending thread to enter an uninterruptible sleep state. SG_IO ioctls are now     rejected by the virtio-blk driver: the ioctl system call will simply return an ENOTTY (Inappropriate ioctl     for device) error and the thread will continue normally.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The encode_share_access function in fs/nfs/nfs4xdr.c in the Linux kernel before 2.6.29 allows local users     to cause a denial of service (BUG and system crash) by using the mknod system call with a pathname on an     NFSv4 filesystem. (CVE-2011-4324)

Note that Nessus relies on the presence of the package as reported by the vendor.

   VMware would like to thank Alexander Minozhenko from ERPScan for    reporting this issue to us.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issues :

  - A buffer overflow flaw was found in the way the Linux     kernel's XFS file system implementation handled links     with overly long path names. A local, unprivileged user     could use this flaw to cause a denial of service or     escalate their privileges by mounting a specially     crafted disk. (CVE-2011-4077, Important)

  - The fix for CVE-2011-2482 provided by a previous update     introduced a regression: on systems that do not have     Security-Enhanced Linux (SELinux) in Enforcing mode, a     socket lock race could occur between sctp_rcv() and     sctp_accept(). A remote attacker could use this flaw to     cause a denial of service. By default, SELinux runs in     Enforcing mode on Scientific Linux 5. (CVE-2011-4348,     Important)

  - The proc file system could allow a local, unprivileged     user to obtain sensitive information or possibly cause     integrity issues. (CVE-2011-1020, Moderate)

  - A missing validation flaw was found in the Linux     kernel's m_stop() implementation. A local, unprivileged     user could use this flaw to trigger a denial of service.
    (CVE-2011-3637, Moderate)

  - A flaw was found in the Linux kernel's Journaling Block     Device (JBD). A local attacker could use this flaw to     crash the system by mounting a specially crafted ext3 or     ext4 disk. (CVE-2011-4132, Moderate)

  - A flaw was found in the Linux kernel's     encode_share_access() implementation. A local,     unprivileged user could use this flaw to trigger a     denial of service by creating a regular file on an NFSv4     (Network File System version 4) file system via mknod().
    (CVE-2011-4324, Moderate)

  - A flaw was found in the Linux kernel's NFS     implementation. A local, unprivileged user could use     this flaw to cause a denial of service. (CVE-2011-4325,     Moderate)

  - A missing boundary check was found in the Linux kernel's     HFS file system implementation. A local attacker could     use this flaw to cause a denial of service or escalate     their privileges by mounting a specially crafted disk.
    (CVE-2011-4330, Moderate)

This update also fixes several bugs and adds one enhancement.

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.

This Linux kernel update fixes various security issues and bugs in the SUSE Linux Enterprise 10 SP4 kernel.

  - The dl2k network card driver lacked permission handling     for some ethtool ioctls, which could allow local     attackers to start/stop the network card.
    (CVE-2012-2313)

  - The befs_follow_linkl function in fs/befs/linuxvfs.c in     the Linux kernel did not validate the lenght attribute     of long symlinsk, which allowed local users to cause a     denial of service (incorrect pointer dereference and     Ooops) by accessing a long symlink on a malformed Be     filesystem. (CVE-2011-2928)

  - Fixed a memory corruption possibility in xfs readlink,     which could be used by local attackers to crash the     system or potentially execute code by mounting a     prepared xfs filesystem image. (CVE-2011-4077)

  - A BUG() error report in the nfs4xdr routines on a NFSv4     mount was fixed that could happen during mknod.
    (CVE-2011-4324)
