(bnc#873374). (CVE-2014-2851) - The try_to_unmap_cluster function in mm/rmap.c in the Linux kernel before 3.14.3 does not properly consider which pages must be locked, which allows local users to cause a denial of service (system crash) by triggering a memory-usage pattern that requires removal of page-table mappings. (bnc#876102). (CVE-2014-3122) - The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 do not check whether a certain length value is sufficiently large, which allows local users to cause a denial of service (integer underflow and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr and __skb_get_nlattr_nest functions before the vulnerability was announced. (bnc#877257). (CVE-2014-3144) - The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr_nest function before the vulnerability was announced. (bnc#877257). (CVE-2014-3145) - kernel/auditsc.c in the Linux kernel through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allows local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number. (bnc#880484). (CVE-2014-3917) - arch/x86/kernel/entry_32.S in the Linux kernel through 3.15.1 on 32-bit x86 platforms, when syscall auditing is enabled and the sep CPU feature flag is set, allows local users to cause a denial of service (OOPS and system crash) via an invalid syscall number, as demonstrated by number.

(bnc#883795). (CVE-2014-4652) - sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not ensure possession of a read/write lock, which allows local users to cause a denial of service (use-after-free) and obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access. (bnc#883795). (CVE-2014-4653) - The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allows local users to remove kernel controls and cause a denial of service (use-after-free and system crash) by leveraging /dev/snd/controlCX access for an ioctl call. (bnc#883795). (CVE-2014-4654) - The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not properly maintain the user_ctl_count value, which allows local users to cause a denial of service (integer overflow and limit bypass) by leveraging /dev/snd/controlCX access for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls. (bnc#883795). (CVE-2014-4655) - Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allow local users to cause a denial of service by leveraging /dev/snd/controlCX access, related to (1) index values in the snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function. (bnc#883795). (CVE-2014-4656) - The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls.

    NASL id ORACLELINUX_ELSA-2012-0743.NASL
    description From Red Hat Security Advisory 2012:0743 : Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6. 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. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * A local, unprivileged user could use an integer overflow flaw in drm_mode_dirtyfb_ioctl() to cause a denial of service or escalate their privileges. (CVE-2012-0044, Important) * A buffer overflow flaw was found in the macvtap device driver, used for creating a bridged network between the guest and the host in KVM (Kernel-based Virtual Machine) environments. A privileged guest user in a KVM guest could use this flaw to crash the host. Note: This issue only affected hosts that have the vhost_net module loaded with the experimental_zcopytx module option enabled (it is not enabled by default), and that also have macvtap configured for at least one guest. (CVE-2012-2119, Important) * When a set user ID (setuid) application is executed, certain personality flags for controlling the application's behavior are cleared (that is, a privileged application will not be affected by those flags). It was found that those flags were not cleared if the application was made privileged via file system capabilities. A local, unprivileged user could use this flaw to change the behavior of such applications, allowing them to bypass intended restrictions. Note that for default installations, no application shipped by Red Hat for Red Hat Enterprise Linux is made privileged via file system capabilities. (CVE-2012-2123, Important) * It was found that the data_len parameter of the sock_alloc_send_pskb() function in the Linux kernel's networking implementation was not validated before use. A privileged guest user in a KVM guest could use this flaw to crash the host or, possibly, escalate their privileges on the host. (CVE-2012-2136, Important) * A buffer overflow flaw was found in the setup_routing_entry() function in the KVM subsystem of the Linux kernel in the way the Message Signaled Interrupts (MSI) routing entry was handled. A local, unprivileged user could use this flaw to cause a denial of service or, possibly, escalate their privileges. (CVE-2012-2137, Important) * A race condition was found in the Linux kernel's memory management subsystem in the way pmd_none_or_clear_bad(), when called with mmap_sem in read mode, and Transparent Huge Pages (THP) page faults interacted. A privileged user in a KVM guest with the ballooning functionality enabled could potentially use this flaw to crash the host. A local, unprivileged user could use this flaw to crash the system. (CVE-2012-1179, Moderate) * A flaw was found in the way device memory was handled during guest device removal. Upon successful device removal, memory used by the device was not properly unmapped from the corresponding IOMMU or properly released from the kernel, leading to a memory leak. A malicious user on a KVM host who has the ability to assign a device to a guest could use this flaw to crash the host.

  • NASL family Scientific Linux Local Security Checks
    NASL id SL_20120618_KERNEL_ON_SL6_X.NASL
    description The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : - A local, unprivileged user could use an integer overflow flaw in drm_mode_dirtyfb_ioctl() to cause a denial of service or escalate their privileges. (CVE-2012-0044, Important) - A buffer overflow flaw was found in the macvtap device driver, used for creating a bridged network between the guest and the host in KVM (Kernel-based Virtual Machine) environments. A privileged guest user in a KVM guest could use this flaw to crash the host. Note: This issue only affected hosts that have the vhost_net module loaded with the experimental_zcopytx module option enabled (it is not enabled by default), and that also have macvtap configured for at least one guest. (CVE-2012-2119, Important) - When a set user ID (setuid) application is executed, certain personality flags for controlling the application's behavior are cleared (that is, a privileged application will not be affected by those flags). It was found that those flags were not cleared if the application was made privileged via file system capabilities. A local, unprivileged user could use this flaw to change the behavior of such applications, allowing them to bypass intended restrictions. Note that for default installations, no application shipped by us for Scientific Linux is made privileged via file system capabilities. (CVE-2012-2123, Important) - It was found that the data_len parameter of the sock_alloc_send_pskb() function in the Linux kernel's networking implementation was not validated before use. A privileged guest user in a KVM guest could use this flaw to crash the host or, possibly, escalate their privileges on the host. (CVE-2012-2136, Important) - A buffer overflow flaw was found in the setup_routing_entry() function in the KVM subsystem of the Linux kernel in the way the Message Signaled Interrupts (MSI) routing entry was handled. A local, unprivileged user could use this flaw to cause a denial of service or, possibly, escalate their privileges. (CVE-2012-2137, Important) - A race condition was found in the Linux kernel's memory management subsystem in the way pmd_none_or_clear_bad(), when called with mmap_sem in read mode, and Transparent Huge Pages (THP) page faults interacted. A privileged user in a KVM guest with the ballooning functionality enabled could potentially use this flaw to crash the host. A local, unprivileged user could use this flaw to crash the system. (CVE-2012-1179, Moderate) - A flaw was found in the way device memory was handled during guest device removal. Upon successful device removal, memory used by the device was not properly unmapped from the corresponding IOMMU or properly released from the kernel, leading to a memory leak. A malicious user on a KVM host who has the ability to assign a device to a guest could use this flaw to crash the host. (CVE-2012-2121, Moderate) - A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2372, Moderate) - A race condition was found in the Linux kernel's memory management subsystem in the way pmd_populate() and pte_offset_map_lock() interacted on 32-bit x86 systems with more than 4GB of RAM. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2373, Moderate) This update also fixes several bugs.

    title Scientific Linux Security Update : kernel on SL6.x i386/x86_64
  • NASL family SuSE Local Security Checks
    NASL id SUSE_11_KERNEL-121203.NASL
    description The SUSE Linux Enterprise 11 SP2 kernel has been updated to 3.0.51 which fixes various bugs and security issues. It contains the following feature enhancements : - The cachefiles framework is now supported (FATE#312793, bnc#782369). The userland utilities were published seperately to support this feature. - The ipset netfilter modules are now supported (FATE#313309) The ipset userland utility will be published seperately to support this feature. - The tipc kernel module is now externally supported (FATE#305033). - Hyper-V KVP IP injection was implemented (FATE#314441). A seperate hyper-v package will be published to support this feature. - Intel Lynx Point PCH chipset support was added. (FATE#313409) - Enable various md/raid10 and DASD enhancements. (FATE#311379) These make it possible for RAID10 to cope with DASD devices being slow for various reasons - the affected device will be temporarily removed from the array. Also added support for reshaping of RAID10 arrays. mdadm changes will be published to support this feature. The following security issues have been fixed : - A race condition on hot adding memory could be used by local attackers to crash the system during hot adding new memory. (CVE-2012-5517) - A flaw has been found in the way Linux kernels KVM subsystem handled vcpu->arch.cr4 X86_CR4_OSXSAVE bit set upon guest enter. On hosts without the XSAVE feature and using qemu userspace an unprivileged local user could have used this flaw to crash the system. (CVE-2012-4461) - The KVM implementation in the Linux kernel allowed host OS users to cause a denial of service (NULL pointer dereference and host OS crash) by making a KVM_CREATE_IRQCHIP ioctl call after a virtual CPU already exists. (CVE-2012-1601) - Attempting an rds connection from the IP address of an IPoIB interface to itself causes a kernel panic due to a BUG_ON() being triggered. Making the test less strict allows rds-ping to work without crashing the machine. A local unprivileged user could use this flaw to crash the sytem. (CVE-2012-2372) - Dimitry Monakhov, one of the ext4 developers, has discovered a race involving asynchronous I/O and fallocate which can lead to the exposure of stale data --- that is, an extent which should have had the 'uninitialized' bit set indicating that its blocks have not yet been written and thus contain data from a deleted file will get exposed to anyone with read access to the file. (CVE-2012-4508) - The rds_recvmsg function in net/rds/recv.c in the Linux kernel did not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a (1) recvfrom or (2) recvmsg system call on an RDS socket. (CVE-2012-3430) - The sfc (aka Solarflare Solarstorm) driver in the Linux kernel allowed remote attackers to cause a denial of service (DMA descriptor consumption and network-controller outage) via crafted TCP packets that trigger a small MSS value. (CVE-2012-3412) The following non-security issues have been fixed : BTRFS : - btrfs: fix double mntput() in mount_subvol(). - btrfs: use common work instead of delayed work - btrfs: limit fallocate extent reservation to 256MB - btrfs: fix a double free on pending snapshots in error handling - btrfs: Do not trust the superblock label and simply printk('%s') it - patches.suse/btrfs-update-message-levels.patch: Refresh. - patches.suse/btrfs-enospc-debugging-messages.patch: Minor updates. - patches.suse/btrfs-update-message-levels.patch: Minor updates. - btrfs: continue after abort during snapshot drop.

    title VMSA-2013-0015 : VMware ESX updates to third-party libraries
  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2012-0743.NASL
    description Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6. 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. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * A local, unprivileged user could use an integer overflow flaw in drm_mode_dirtyfb_ioctl() to cause a denial of service or escalate their privileges. (CVE-2012-0044, Important) * A buffer overflow flaw was found in the macvtap device driver, used for creating a bridged network between the guest and the host in KVM (Kernel-based Virtual Machine) environments. A privileged guest user in a KVM guest could use this flaw to crash the host. Note: This issue only affected hosts that have the vhost_net module loaded with the experimental_zcopytx module option enabled (it is not enabled by default), and that also have macvtap configured for at least one guest. (CVE-2012-2119, Important) * When a set user ID (setuid) application is executed, certain personality flags for controlling the application's behavior are cleared (that is, a privileged application will not be affected by those flags). It was found that those flags were not cleared if the application was made privileged via file system capabilities. A local, unprivileged user could use this flaw to change the behavior of such applications, allowing them to bypass intended restrictions. Note that for default installations, no application shipped by Red Hat for Red Hat Enterprise Linux is made privileged via file system capabilities. (CVE-2012-2123, Important) * It was found that the data_len parameter of the sock_alloc_send_pskb() function in the Linux kernel's networking implementation was not validated before use. A privileged guest user in a KVM guest could use this flaw to crash the host or, possibly, escalate their privileges on the host. (CVE-2012-2136, Important) * A buffer overflow flaw was found in the setup_routing_entry() function in the KVM subsystem of the Linux kernel in the way the Message Signaled Interrupts (MSI) routing entry was handled. A local, unprivileged user could use this flaw to cause a denial of service or, possibly, escalate their privileges. (CVE-2012-2137, Important) * A race condition was found in the Linux kernel's memory management subsystem in the way pmd_none_or_clear_bad(), when called with mmap_sem in read mode, and Transparent Huge Pages (THP) page faults interacted. A privileged user in a KVM guest with the ballooning functionality enabled could potentially use this flaw to crash the host. A local, unprivileged user could use this flaw to crash the system. (CVE-2012-1179, Moderate) * A flaw was found in the way device memory was handled during guest device removal. Upon successful device removal, memory used by the device was not properly unmapped from the corresponding IOMMU or properly released from the kernel, leading to a memory leak. A malicious user on a KVM host who has the ability to assign a device to a guest could use this flaw to crash the host. (CVE-2012-2121, Moderate) * A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2372, Moderate) * A race condition was found in the Linux kernel's memory management subsystem in the way pmd_populate() and pte_offset_map_lock() interacted on 32-bit x86 systems with more than 4GB of RAM. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2373, Moderate) Red Hat would like to thank Chen Haogang for reporting CVE-2012-0044. This update also fixes several bugs. 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 noted in the Technical Notes. The system must be rebooted for this update to take effect.

    description A flaw was found in the way the Linux kernel's Event Poll (epoll) subsystem handled large, nested epoll structures. A local, unprivileged user could use this flaw to cause a denial of service. A malicious Network File System version 4 (NFSv4) server could return a crafted reply to a GETACL request, causing a denial of service on the client. The rds_ib_xmit function in net/rds/ib_send.c in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel 3.7.4 and earlier allows local users to cause a denial of service (BUG_ON and kernel panic) by establishing an RDS connection with the source IP address equal to the IPoIB interface's own IP address, as demonstrated by rds-ping.

    NASL id SL_20121204_KERNEL_ON_SL5_X.NASL
    description Security fixes : - A race condition in the way asynchronous I/O and fallocate() interacted when using ext4 could allow a local, unprivileged user to obtain random data from a deleted file. (CVE-2012-4508, Important) - A flaw in the way the Xen hypervisor implementation range checked guest provided addresses in the XENMEM_exchange hypercall could allow a malicious, para-virtualized guest administrator to crash the hypervisor or, potentially, escalate their privileges, allowing them to execute arbitrary code at the hypervisor level. (CVE-2012-5513, Important) - A flaw in the Reliable Datagram Sockets (RDS) protocol implementation could allow a local, unprivileged user to cause a denial of service. (CVE-2012-2372, Moderate) - A race condition in the way access to inet->opt ip_options was synchronized in the Linux kernel's TCP/IP protocol suite implementation. Depending on the network facing applications running on the system, a remote attacker could possibly trigger this flaw to cause a denial of service. A local, unprivileged user could use this flaw to cause a denial of service regardless of the applications the system runs. (CVE-2012-3552, Moderate) - The Xen hypervisor implementation did not properly restrict the period values used to initialize per VCPU periodic timers. A privileged guest user could cause an infinite loop on the physical CPU. If the watchdog were enabled, it would detect said loop and panic the host system. (CVE-2012-4535, Moderate) - A flaw in the way the Xen hypervisor implementation handled set_p2m_entry() error conditions could allow a privileged, fully-virtualized guest user to crash the hypervisor. (CVE-2012-4537, Moderate) Bug fixes : - Previously, the interrupt handlers of the qla2xxx driver could clear pending interrupts right after the IRQ lines were attached during system start-up. Consequently, the kernel could miss the interrupt that reported completion of the link initialization, and the qla2xxx driver then failed to detect all attached LUNs. With this update, the qla2xxx driver has been modified to no longer clear interrupt bits after attaching the IRQ lines. The driver now correctly detects all attached LUNs as expected. - The Ethernet channel bonding driver reported the MII (Media Independent Interface) status of the bond interface in 802.3ad mode as being up even though the MII status of all of the slave devices was down. This could pose a problem if the MII status of the bond interface was used to determine if failover should occur. With this update, the agg_device_up() function has been added to the bonding driver, which allows the driver to report the link status of the bond interface correctly, that is, down when all of its slaves are down, in the 802.3ad mode. Enhancements : - This update backports several changes from the latest upstream version of the bnx2x driver. The most important change, the remote-fault link detection feature, allows the driver to periodically scan the physical link layer for remote faults. If the physical link appears to be up and a fault is detected, the driver indicates that the link is down. When the fault is cleared, the driver indicates that the link is up again. - The INET socket interface has been modified to send a warning message when the ip_options structure is allocated directly by a third-party module using the kmalloc() function. The system must be rebooted for this update to take effect.

    title SuSE 10 Security Update : OFED (ZYPP Patch Number 8507)
  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2012-1540.NASL
    description Updated kernel packages that fix multiple security issues, two bugs, and add two enhancements 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. These packages contain the Linux kernel. Security fixes : * A race condition in the way asynchronous I/O and fallocate() interacted when using ext4 could allow a local, unprivileged user to obtain random data from a deleted file. (CVE-2012-4508, Important) * A flaw in the way the Xen hypervisor implementation range checked guest provided addresses in the XENMEM_exchange hypercall could allow a malicious, para-virtualized guest administrator to crash the hypervisor or, potentially, escalate their privileges, allowing them to execute arbitrary code at the hypervisor level. (CVE-2012-5513, Important) * A flaw in the Reliable Datagram Sockets (RDS) protocol implementation could allow a local, unprivileged user to cause a denial of service. (CVE-2012-2372, Moderate) * A race condition in the way access to inet->opt ip_options was synchronized in the Linux kernel's TCP/IP protocol suite implementation. Depending on the network facing applications running on the system, a remote attacker could possibly trigger this flaw to cause a denial of service. A local, unprivileged user could use this flaw to cause a denial of service regardless of the applications the system runs. (CVE-2012-3552, Moderate) * The Xen hypervisor implementation did not properly restrict the period values used to initialize per VCPU periodic timers. A privileged guest user could cause an infinite loop on the physical CPU. If the watchdog were enabled, it would detect said loop and panic the host system. (CVE-2012-4535, Moderate) * A flaw in the way the Xen hypervisor implementation handled set_p2m_entry() error conditions could allow a privileged, fully-virtualized guest user to crash the hypervisor. (CVE-2012-4537, Moderate) Red Hat would like to thank Theodore Ts'o for reporting CVE-2012-4508; the Xen project for reporting CVE-2012-5513, CVE-2012-4535, and CVE-2012-4537; and Hafid Lin for reporting CVE-2012-3552. Upstream acknowledges Dmitry Monakhov as the original reporter of CVE-2012-4508. CVE-2012-2372 was discovered by Li Honggang of Red Hat. Bug fixes : * Previously, the interrupt handlers of the qla2xxx driver could clear pending interrupts right after the IRQ lines were attached during system start-up. Consequently, the kernel could miss the interrupt that reported completion of the link initialization, and the qla2xxx driver then failed to detect all attached LUNs. With this update, the qla2xxx driver has been modified to no longer clear interrupt bits after attaching the IRQ lines. The driver now correctly detects all attached LUNs as expected. (BZ#870118) * The Ethernet channel bonding driver reported the MII (Media Independent Interface) status of the bond interface in 802.3ad mode as being up even though the MII status of all of the slave devices was down. This could pose a problem if the MII status of the bond interface was used to determine if failover should occur. With this update, the agg_device_up() function has been added to the bonding driver, which allows the driver to report the link status of the bond interface correctly, that is, down when all of its slaves are down, in the 802.3ad mode. (BZ#877943) Enhancements : * This update backports several changes from the latest upstream version of the bnx2x driver. The most important change, the remote-fault link detection feature, allows the driver to periodically scan the physical link layer for remote faults. If the physical link appears to be up and a fault is detected, the driver indicates that the link is down. When the fault is cleared, the driver indicates that the link is up again. (BZ#870120) * The INET socket interface has been modified to send a warning message when the ip_options structure is allocated directly by a third-party module using the kmalloc() function. (BZ#874973) Users should upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. The system must be rebooted for this update to take effect.

    description A flaw was discovered in the Linux kernel's macvtap device driver, which is used in KVM (Kernel-based Virtual Machine) to create a network bridge between host and guest. A privleged user in a guest could exploit this flaw to crash the host, if the vhost_net module is loaded with the experimental_zcopytx option enabled. (CVE-2012-2119) 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) A flaw was found in how the Linux kernel's KVM (Kernel-based Virtual Machine) subsystem handled MSI (Message Signaled Interrupts). A local unprivileged user could exploit this flaw to cause a denial of service or potentially elevate privileges. (CVE-2012-2137) A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2372) 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) Dan Rosenberg discovered flaws in the Linux kernel's NCI (Near Field Communication Controller Interface). A remote attacker could exploit these flaws to crash the system or potentially execute privileged code. (CVE-2012-3364) 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)
