Summary

An issue was discovered in Xen through 4.10.x allowing x86 HVM guest OS users to cause a denial of service (unexpectedly high interrupt number, array overrun, and hypervisor crash) or possibly gain hypervisor privileges by setting up an HPET timer to deliver interrupts in IO-APIC mode, aka vHPET interrupt injection.

    descriptionThis update for xen fixes the following issues: These security issue were fixed : - CVE-2018-3646: Systems with microprocessors utilizing speculative execution and address translations may have allowed unauthorized disclosure of information residing in the L1 data cache to an attacker with local user access with guest OS privilege via a terminal page fault and a side-channel analysis (bsc#1091107, bsc#1027519). - CVE-2018-12617: An integer overflow that could cause a segmentation fault in qmp_guest_file_read() with g_malloc() in qemu-guest-agent was fixed (bsc#1098744) - CVE-2018-3665: System software utilizing Lazy FP state restore technique on systems using Intel Core-based microprocessors may potentially allow a local process to infer data from another process through a speculative execution side channel. (bsc#1095242) - CVE-2018-3639: Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4. (bsc#1092631) - CVE-2017-5715: Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. (bsc#1074562) - CVE-2017-5753: Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. (bsc#1074562) - CVE-2017-5754: Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis of the data cache. (bsc#1074562) - CVE-2018-12891: Certain PV MMU operations may take a long time to process. For that reason Xen explicitly checks for the need to preempt the current vCPU at certain points. A few rarely taken code paths did bypass such checks. By suitably enforcing the conditions through its own page table contents, a malicious guest may cause such bypasses to be used for an unbounded number of iterations. A malicious or buggy PV guest may cause a Denial of Service (DoS) affecting the entire host. Specifically, it may prevent use of a physical CPU for an indeterminate period of time. (bsc#1097521) - CVE-2018-12893: One of the fixes in XSA-260 added some safety checks to help prevent Xen livelocking with debug exceptions. Unfortunately, due to an oversight, at least one of these safety checks can be triggered by a guest. A malicious PV guest can crash Xen, leading to a Denial of Service. Only x86 PV guests can exploit the vulnerability. x86 HVM and PVH guests cannot exploit the vulnerability. An attacker needs to be able to control hardware debugging facilities to exploit the vulnerability, but such permissions are typically available to unprivileged users. (bsc#1097522) - CVE-2018-11806: m_cat in slirp/mbuf.c in Qemu has a heap-based buffer overflow via incoming fragmented datagrams. (bsc#1096224) - CVE-2018-10982: An issue was discovered in Xen allowed x86 HVM guest OS users to cause a denial of service (unexpectedly high interrupt number, array overrun, and hypervisor crash) or possibly gain hypervisor privileges by setting up an HPET timer to deliver interrupts in IO-APIC mode, aka vHPET interrupt injection. (bsc#1090822) - CVE-2018-10981: An issue was discovered in Xen that allowed x86 HVM guest OS users to cause a denial of service (host OS infinite loop) in situations where a QEMU device model attempts to make invalid transitions between states of a request. (bsc#1090823) Following bugs were fixed : - After updating to kernel 3.0.101-0.47.106.32-xen system crashes in check_bugs() (bsc#1097206) - bsc#1079730 - in xen-kmp, unplug emulated devices after migration This is required since xen-4.10 and/or qemu-2.10 because the state of unplug is not propagated from one dom0 to another. Without this unplug qemu

        allowed unauthorized disclosure of information residing
        in the L1 data cache to an attacker with local user
        access with guest OS privilege via a terminal page fault
        and a side-channel analysis (bsc#1091107, bsc#1027519).
    
      - CVE-2018-12617: An integer overflow that could cause a
        segmentation fault in qmp_guest_file_read() with
        g_malloc() in qemu-guest-agent was fixed (bsc#1098744)
    
      - CVE-2018-3665: System software utilizing Lazy FP state
        restore technique on systems using Intel Core-based
        microprocessors may potentially allow a local process to
        infer data from another process through a speculative
        execution side channel. (bsc#1095242)
    
      - CVE-2018-3639: Systems with microprocessors utilizing
        speculative execution and speculative execution of
        memory reads before the addresses of all prior memory
        writes are known may allow unauthorized disclosure of
        information to an attacker with local user access via a
        side-channel analysis, aka Speculative Store Bypass
        (SSB), Variant 4. (bsc#1092631)
    
      - CVE-2017-5715: Systems with microprocessors utilizing
        speculative execution and indirect branch prediction may
        allow unauthorized disclosure of information to an
        attacker with local user access via a side-channel
        analysis. (bsc#1074562)
    
      - CVE-2017-5753: Systems with microprocessors utilizing
        speculative execution and branch prediction may allow
        unauthorized disclosure of information to an attacker
        with local user access via a side-channel analysis.
        (bsc#1074562)
    
      - CVE-2017-5754: Systems with microprocessors utilizing
        speculative execution and indirect branch prediction may
        allow unauthorized disclosure of information to an
        attacker with local user access via a side-channel
        analysis of the data cache. (bsc#1074562)
    
      - CVE-2018-12891: Certain PV MMU operations may take a
        long time to process. For that reason Xen explicitly
        checks for the need to preempt the current vCPU at
        certain points. A few rarely taken code paths did bypass
        such checks. By suitably enforcing the conditions
        through its own page table contents, a malicious guest
        may cause such bypasses to be used for an unbounded
        number of iterations. A malicious or buggy PV guest may
        cause a Denial of Service (DoS) affecting the entire
        host. Specifically, it may prevent use of a physical CPU
        for an indeterminate period of time. (bsc#1097521)
    
      - CVE-2018-12893: One of the fixes in XSA-260 added some
        safety checks to help prevent Xen livelocking with debug
        exceptions. Unfortunately, due to an oversight, at least
        one of these safety checks can be triggered by a guest.
        A malicious PV guest can crash Xen, leading to a Denial
        of Service. Only x86 PV guests can exploit the
        vulnerability. x86 HVM and PVH guests cannot exploit the
        vulnerability. An attacker needs to be able to control
        hardware debugging facilities to exploit the
        vulnerability, but such permissions are typically
        available to unprivileged users. (bsc#1097522)
    
      - CVE-2018-11806: m_cat in slirp/mbuf.c in Qemu has a
        heap-based buffer overflow via incoming fragmented
        datagrams. (bsc#1096224)
    
      - CVE-2018-10982: An issue was discovered in Xen allowed
        x86 HVM guest OS users to cause a denial of service
        (unexpectedly high interrupt number, array overrun, and
        hypervisor crash) or possibly gain hypervisor privileges
        by setting up an HPET timer to deliver interrupts in
        IO-APIC mode, aka vHPET interrupt injection.
        (bsc#1090822)
    
      - CVE-2018-10981: An issue was discovered in Xen that
        allowed x86 HVM guest OS users to cause a denial of
        service (host OS infinite loop) in situations where a
        QEMU device model attempts to make invalid transitions
        between states of a request. (bsc#1090823) Following
        bugs were fixed :
    
      - After updating to kernel 3.0.101-0.47.106.32-xen system
        crashes in check_bugs() (bsc#1097206)
    
      - bsc#1079730 - in xen-kmp, unplug emulated devices after
        migration This is required since xen-4.10 and/or
        qemu-2.10 because the state of unplug is not propagated
        from one dom0 to another. Without this unplug qemu's
        block-backend will be unable to open qcow2 disks on the
        receiving dom0
