Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionqemu was updated to fix 21 security issues. These security issues were fixed : - CVE-2014-5388: Off-by-one error in the pci_read function in the ACPI PCI hotplug interface (hw/acpi/pcihp.c) in QEMU allowed local guest users to obtain sensitive information and have other unspecified impact related to a crafted PCI device that triggers memory corruption (bsc#893323). - CVE-2015-6815: e1000 NIC emulation support was vulnerable to an infinite loop issue. A privileged user inside guest could have used this flaw to crash the Qemu instance resulting in DoS.

    descriptionkvm was updated to fix 16 security issues. These security issues were fixed : - CVE-2015-6815: e1000 NIC emulation support was vulnerable to an infinite loop issue. A privileged user inside guest could have used this flaw to crash the Qemu instance resulting in DoS. (bsc#944697). - CVE-2016-2391: The ohci_bus_start function in the USB OHCI emulation support (hw/usb/hcd-ohci.c) in QEMU allowed local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors related to multiple eof_timers (bsc#967013). - CVE-2016-2392: The is_rndis function in the USB Net device emulator (hw/usb/dev-network.c) in QEMU did not properly validate USB configuration descriptor objects, which allowed local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors involving a remote NDIS control message packet (bsc#967012). - CVE-2016-4453: The vmsvga_fifo_run function in hw/display/vmware_vga.c in QEMU allowed local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via a VGA command (bsc#982223). - CVE-2016-4454: The vmsvga_fifo_read_raw function in hw/display/vmware_vga.c in QEMU allowed local guest OS administrators to obtain sensitive host memory information or cause a denial of service (QEMU process crash) by changing FIFO registers and issuing a VGA command, which triggers an out-of-bounds read (bsc#982222). - CVE-2016-5105: The megasas_dcmd_cfg_read function in hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, used an uninitialized variable, which allowed local guest administrators to read host memory via vectors involving a MegaRAID Firmware Interface (MFI) command (bsc#982017). - CVE-2016-5106: The megasas_dcmd_set_properties function in hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, allowed local guest administrators to cause a denial of service (out-of-bounds write access) via vectors involving a MegaRAID Firmware Interface (MFI) command (bsc#982018). - CVE-2016-5107: The megasas_lookup_frame function in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, allowed local guest OS administrators to cause a denial of service (out-of-bounds read and crash) via unspecified vectors (bsc#982019). - CVE-2016-5126: Heap-based buffer overflow in the iscsi_aio_ioctl function in block/iscsi.c in QEMU allowed local guest OS users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code via a crafted iSCSI asynchronous I/O ioctl call (bsc#982285). - CVE-2016-5238: The get_cmd function in hw/scsi/esp.c in QEMU allowed local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via vectors related to reading from the information transfer buffer in non-DMA mode (bsc#982959). - CVE-2016-5337: The megasas_ctrl_get_info function in hw/scsi/megasas.c in QEMU allowed local guest OS administrators to obtain sensitive host memory information via vectors related to reading device control information (bsc#983961). - CVE-2016-5338: The (1) esp_reg_read and (2) esp_reg_write functions in hw/scsi/esp.c in QEMU allowed local guest OS administrators to cause a denial of service (QEMU process crash) or execute arbitrary code on the QEMU host via vectors related to the information transfer buffer (bsc#983982). - CVE-2016-5403: The virtqueue_pop function in hw/virtio/virtio.c in QEMU allowed local guest OS administrators to cause a denial of service (memory consumption and QEMU process crash) by submitting requests without waiting for completion (bsc#991080). - CVE-2016-6490: Infinite loop in the virtio framework. A privileged user inside the guest could have used this flaw to crash the Qemu instance on the host resulting in DoS (bsc#991466). - CVE-2016-7116: Host directory sharing via Plan 9 File System(9pfs) was vulnerable to a directory/path traversal issue. A privileged user inside guest could have used this flaw to access undue files on the host (bsc#996441). - CVE-2014-7815: The set_pixel_format function in ui/vnc.c in QEMU allowed remote attackers to cause a denial of service (crash) via a small bytes_per_pixel value (bsc#902737).

    "kvm was updated to fix 16 security issues. These security issues were
    fixed :
    
      - CVE-2015-6815: e1000 NIC emulation support was
        vulnerable to an infinite loop issue. A privileged user
        inside guest could have used this flaw to crash the Qemu
        instance resulting in DoS. (bsc#944697).
    
      - CVE-2016-2391: The ohci_bus_start function in the USB
        OHCI emulation support (hw/usb/hcd-ohci.c) in QEMU
        allowed local guest OS administrators to cause a denial
        of service (NULL pointer dereference and QEMU process
        crash) via vectors related to multiple eof_timers
        (bsc#967013).
    
      - CVE-2016-2392: The is_rndis function in the USB Net
        device emulator (hw/usb/dev-network.c) in QEMU did not
        properly validate USB configuration descriptor objects,
        which allowed local guest OS administrators to cause a
        denial of service (NULL pointer dereference and QEMU
        process crash) via vectors involving a remote NDIS
        control message packet (bsc#967012).
    
      - CVE-2016-4453: The vmsvga_fifo_run function in
        hw/display/vmware_vga.c in QEMU allowed local guest OS
        administrators to cause a denial of service (infinite
        loop and QEMU process crash) via a VGA command
        (bsc#982223).
    
      - CVE-2016-4454: The vmsvga_fifo_read_raw function in
        hw/display/vmware_vga.c in QEMU allowed local guest OS
        administrators to obtain sensitive host memory
        information or cause a denial of service (QEMU process
        crash) by changing FIFO registers and issuing a VGA
        command, which triggers an out-of-bounds read
        (bsc#982222).
    
      - CVE-2016-5105: The megasas_dcmd_cfg_read function in
        hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS
        8708EM2 Host Bus Adapter emulation support, used an
        uninitialized variable, which allowed local guest
        administrators to read host memory via vectors involving
        a MegaRAID Firmware Interface (MFI) command
        (bsc#982017).
    
      - CVE-2016-5106: The megasas_dcmd_set_properties function
        in hw/scsi/megasas.c in QEMU, when built with MegaRAID
        SAS 8708EM2 Host Bus Adapter emulation support, allowed
        local guest administrators to cause a denial of service
        (out-of-bounds write access) via vectors involving a
        MegaRAID Firmware Interface (MFI) command (bsc#982018).
    
      - CVE-2016-5107: The megasas_lookup_frame function in
        QEMU, when built with MegaRAID SAS 8708EM2 Host Bus
        Adapter emulation support, allowed local guest OS
        administrators to cause a denial of service
        (out-of-bounds read and crash) via unspecified vectors
        (bsc#982019).
    
      - CVE-2016-5126: Heap-based buffer overflow in the
        iscsi_aio_ioctl function in block/iscsi.c in QEMU
        allowed local guest OS users to cause a denial of
        service (QEMU process crash) or possibly execute
        arbitrary code via a crafted iSCSI asynchronous I/O
        ioctl call (bsc#982285).
    
      - CVE-2016-5238: The get_cmd function in hw/scsi/esp.c in
        QEMU allowed local guest OS administrators to cause a
        denial of service (out-of-bounds write and QEMU process
        crash) via vectors related to reading from the
        information transfer buffer in non-DMA mode
        (bsc#982959).
    
      - CVE-2016-5337: The megasas_ctrl_get_info function in
        hw/scsi/megasas.c in QEMU allowed local guest OS
        administrators to obtain sensitive host memory
        information via vectors related to reading device
        control information (bsc#983961).
    
      - CVE-2016-5338: The (1) esp_reg_read and (2)
        esp_reg_write functions in hw/scsi/esp.c in QEMU allowed
        local guest OS administrators to cause a denial of
        service (QEMU process crash) or execute arbitrary code
        on the QEMU host via vectors related to the information
        transfer buffer (bsc#983982).
    
      - CVE-2016-5403: The virtqueue_pop function in
        hw/virtio/virtio.c in QEMU allowed local guest OS
        administrators to cause a denial of service (memory
        consumption and QEMU process crash) by submitting
        requests without waiting for completion (bsc#991080).
    
      - CVE-2016-6490: Infinite loop in the virtio framework. A
        privileged user inside the guest could have used this
        flaw to crash the Qemu instance on the host resulting in
        DoS (bsc#991466).
    
      - CVE-2016-7116: Host directory sharing via Plan 9 File
        System(9pfs) was vulnerable to a directory/path
        traversal issue. A privileged user inside guest could
        have used this flaw to access undue files on the host
        (bsc#996441).
    
      - CVE-2014-7815: The set_pixel_format function in ui/vnc.c
        in QEMU allowed remote attackers to cause a denial of
        service (crash) via a small bytes_per_pixel value
        (bsc#902737).
