Summary

Quick emulator (Qemu) built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to a divide by zero issue. It could occur while copying VGA data when cirrus graphics mode was set to be VGA. A privileged user inside guest could use this flaw to crash the Qemu process instance on the host, resulting in DoS.

    fixed :
    
      - CVE-2017-2620: In CIRRUS_BLTMODE_MEMSYSSRC mode the
        bitblit copy routine cirrus_bitblt_cputovideo failed to
        check the memory region, allowing for an out-of-bounds
        write that allows for privilege escalation (bsc#1024972)
    
      - CVE-2017-2615: An error in the bitblt copy operation
        could have allowed a malicious guest administrator to
        cause an out of bounds memory access, possibly leading
        to information disclosure or privilege escalation
        (bsc#1023004)
    
      - CVE-2017-5856: The MegaRAID SAS 8708EM2 Host Bus Adapter
        emulation support was vulnerable to a memory leakage
        issue allowing a privileged user to leak host memory
        resulting in DoS (bsc#1023053)
    
      - CVE-2016-9776: The ColdFire Fast Ethernet Controller
        emulator support was vulnerable to an infinite loop
        issue while receiving packets in 'mcf_fec_receive'. A
        privileged user/process inside guest could have used
        this issue to crash the Qemu process on the host leading
        to DoS (bsc#1013285)
    
      - CVE-2016-9911: The USB EHCI Emulation support was
        vulnerable to a memory leakage issue while processing
        packet data in 'ehci_init_transfer'. A guest
        user/process could have used this issue to leak host
        memory, resulting in DoS for the host (bsc#1014111)
    
      - CVE-2016-9907: The USB redirector usb-guest support was
        vulnerable to a memory leakage flaw when destroying the
        USB redirector in 'usbredir_handle_destroy'. A guest
        user/process could have used this issue to leak host
        memory, resulting in DoS for a host (bsc#1014109)
    
      - CVE-2016-9921: The Cirrus CLGD 54xx VGA Emulator support
        was vulnerable to a divide by zero issue while copying
        VGA data. A privileged user inside guest could have used
        this flaw to crash the process instance on the host,
        resulting in DoS (bsc#1014702)
    
      - CVE-2016-9922: The Cirrus CLGD 54xx VGA Emulator support
        was vulnerable to a divide by zero issue while copying
        VGA data. A privileged user inside guest could have used
        this flaw to crash the process instance on the host,
        resulting in DoS (bsc#1014702)
    
      - CVE-2017-5667: The SDHCI device emulation support was
        vulnerable to an OOB heap access issue allowing a
        privileged user inside the guest to crash the Qemu
        process resulting in DoS or potentially execute
        arbitrary code with privileges of the Qemu process on
        the host (bsc#1022541)
    
      - CVE-2017-5898: The CCID Card device emulator support was
        vulnerable to an integer overflow allowing a privileged
        user inside the guest to crash the Qemu process
        resulting in DoS (bnc#1023907)
    
      - CVE-2016-10155: The i6300esb watchdog emulation support
        was vulnerable to a memory leakage issue allowing a
        privileged user inside the guest to leak memory on the
        host resulting in DoS (bnc#1021129)
