[debian-lts-announce] 20201129 [SECURITY] [DLA 2469-1] qemu security update

https://security.netapp.com/advisory/ntap-20201202-0002/

According to the versions of the qemu-kvm packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - sd_wp_addr in hw/sd/sd.c in QEMU 4.2.0 uses an unvalidated address, which leads to an out-of-bounds read     during sdhci_write() operations. A guest OS user can crash the QEMU process. (CVE-2020-13253)

  - In QEMU 5.0.0 and earlier, es1370_transfer_audio in hw/audio/es1370.c does not properly validate the frame     count, which allows guest OS users to trigger an out-of-bounds access during an es1370_write() operation.
    (CVE-2020-13361)

  - In QEMU 5.0.0 and earlier, megasas_lookup_frame in hw/scsi/megasas.c has an out-of-bounds read via a     crafted reply_queue_head field from a guest OS user. (CVE-2020-13362)

  - address_space_map in exec.c in QEMU 4.2.0 can trigger a NULL pointer dereference related to BounceBuffer.
    (CVE-2020-13659)

  - hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address     in an msi-x mmio operation. (CVE-2020-13754)

  - hw/pci/pci.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access by providing an     address near the end of the PCI configuration space. (CVE-2020-13791)

  - In QEMU through 5.0.0, an assertion failure can occur in the network packet processing. This issue affects     the e1000e and vmxnet3 network devices. A malicious guest user/process could use this flaw to abort the     QEMU process on the host, resulting in a denial of service condition in net_tx_pkt_add_raw_fragment in     hw/net/net_tx_pkt.c. (CVE-2020-16092)

  - A heap-based buffer overflow was found in QEMU through 5.0.0 in the SDHCI device emulation support. It     could occur while doing a multi block SDMA transfer via the sdhci_sdma_transfer_multi_blocks() routine in     hw/sd/sdhci.c. A guest user or process could use this flaw to crash the QEMU process on the host,     resulting in a denial of service condition, or potentially execute arbitrary code with privileges of the     QEMU process on the host. (CVE-2020-17380)

  - QEMU 5.0.0 has a heap-based Buffer Overflow in flatview_read_continue in exec.c because hw/sd/sdhci.c     mishandles a write operation in the SDHC_BLKSIZE case. (CVE-2020-25085)

  - hw/usb/hcd-ohci.c in QEMU 5.0.0 has a stack-based buffer over-read via values obtained from the host     controller driver. (CVE-2020-25624)

  - hw/usb/hcd-ohci.c in QEMU 5.0.0 has an infinite loop when a TD list has a loop. (CVE-2020-25625)

  - eth_get_gso_type in net/eth.c in QEMU 4.2.1 allows guest OS users to trigger an assertion failure. A guest     can crash the QEMU process via packet data that lacks a valid Layer 3 protocol. (CVE-2020-27617)

  - hw/net/e1000e_core.c in QEMU 5.0.0 has an infinite loop via an RX descriptor with a NULL buffer address.
    (CVE-2020-28916)

  - The patch for CVE-2020-17380/CVE-2020-25085 was found to be ineffective, thus making QEMU vulnerable to     the out-of-bounds read/write access issues previously found in the SDHCI controller emulation code. This     flaw allows a malicious privileged guest to crash the QEMU process on the host, resulting in a denial of     service or potential code execution. QEMU up to (including) 5.2.0 is affected by this. (CVE-2021-3409)

  - A potential stack overflow via infinite loop issue was found in various NIC emulators of QEMU in versions     up to and including 5.2.0. The issue occurs in loopback mode of a NIC wherein reentrant DMA checks get     bypassed. A guest user/process may use this flaw to consume CPU cycles or crash the QEMU process on the     host resulting in DoS scenario. (CVE-2021-3416)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2021-3061 advisory.

  - eth_get_gso_type in net/eth.c in QEMU 4.2.1 allows guest OS users to trigger an assertion failure. A guest     can crash the QEMU process via packet data that lacks a valid Layer 3 protocol. (CVE-2020-27617)

  - hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address     in an msi-x mmio operation. (CVE-2020-13754)

  - An out-of-bounds heap buffer access issue was found in the ARM Generic Interrupt Controller emulator of     QEMU up to and including qemu 4.2.0on aarch64 platform. The issue occurs because while writing an     interrupt ID to the controller memory area, it is not masked to be 4 bits wide. It may lead to the said     issue while updating controller state fields and their subsequent processing. A privileged guest user may     use this flaw to crash the QEMU process on the host resulting in DoS scenario. (CVE-2021-20221)

  - A flaw was found in the hivex library in versions before 1.3.20. It is caused due to a lack of bounds     check within the hivex_open function. An attacker could input a specially crafted Windows Registry (hive)     file which would cause hivex to read memory beyond its normal bounds or cause the program to crash. The     highest threat from this vulnerability is to system availability. (CVE-2021-3504)

  - A potential stack overflow via infinite loop issue was found in various NIC emulators of QEMU in versions     up to and including 5.2.0. The issue occurs in loopback mode of a NIC wherein reentrant DMA checks get     bypassed. A guest user/process may use this flaw to consume CPU cycles or crash the QEMU process on the     host resulting in DoS scenario. (CVE-2021-3416)

According to the versions of the qemu-kvm packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in QEMU. A heap-based buffer overflow     vulnerability was found in the SDHCI device emulation     support allowing a guest user or process to crash the     QEMU process on the host resulting in a denial of     service condition, or potentially execute arbitrary     code with privileges of the QEMU process on the host.
    The highest threat from this vulnerability is to data     confidentiality and integrity as well as system     availability.(CVE-2020-17380)

  - A flaw was found in QEMU. An out-of-bounds read/write     access issue was found in the SDHCI Controller emulator     of QEMU. It may occur while doing multi block SDMA, if     transfer block size exceeds the     's->fifo_buffer[s->buf_maxsz]' size which would leave     the current element pointer 's->data_count' pointing     out of bounds. This would lead the subsequent DMA r/w     operation to an OOB access issue where a guest     user/process may use this flaw to crash the QEMU     process resulting in DoS scenario. The highest threat     from this vulnerability is to data confidentiality and     integrity as well as system     availability.(CVE-2020-25085)

  - The patch for CVE-2020-17380 and CVE-2020-25085, both     involving a heap buffer overflow in the SDHCI     controller emulation code of QEMU, was found to be     incomplete. A malicious privileged guest could     reproduce the same issues with specially crafted input,     inducing a bogus transfer and subsequent out-of-bounds     read/write access in sdhci_do_adma() or     sdhci_sdma_transfer_multi_blocks(). CVE-2021-3409 was     assigned to facilitate the tracking and backporting of     the new patch.(CVE-2021-3409)

  - A potential stack overflow via infinite loop issue was     found in various NIC emulators of QEMU. The issue     occurs in loopback mode of a NIC wherein reentrant DMA     checks get bypassed. A guest user/process may use this     flaw to consume CPU cycles or crash the QEMU process on     the host resulting in DoS scenario.(CVE-2021-3416)

  - An infinite loop flaw was found in the USB OHCI     controller emulator of QEMU. This flaw occurs while     servicing OHCI isochronous transfer descriptors (TD) in     the ohci_service_iso_td routine, as it retires a TD if     it has passed its time frame. It does not check if the     TD was already processed and holds an error code in     TD_CC. This issue may happen if the TD list has a loop.
    This flaw allows a guest user or process to consume CPU     cycles on the host, resulting in a denial of     service.(CVE-2020-25625)

  - An infinite loop flaw was found in the e1000e device     emulator in QEMU. This issue could occur while     receiving packets via the     e1000e_write_packet_to_guest() routine, if the     receive(RX) descriptor has a NULL buffer address. This     flaw allows a privileged guest user to cause a denial     of service. The highest threat from this vulnerability     is to system availability.(CVE-2020-28916)

  - An assert(3) failure flaw was found in the networking     helper functions of QEMU. This vulnerability can occur     in the eth_get_gso_type() routine if a packet does not     have a valid networking L3 protocol (ex. IPv4, IPv6)     value. This flaw allows a guest user to crash the QEMU     process on the host, resulting in a denial of     service.(CVE-2020-27617)

  - A use-after-free flaw was found in the USB(xHCI/eHCI)     controller emulators of QEMU. This flaw occurs while     setting up the USB packet as a usb_packet_map() routine     and returns an error that was not checked. This flaw     allows a guest user or process to crash the QEMU     process, resulting in a denial of     service.(CVE-2020-25084)

  - hw/pci/pci.c in QEMU 4.2.0 allows guest OS users to     trigger an out-of-bounds access by providing an address     near the end of the PCI configuration     space.(CVE-2020-13791)

  - hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to     trigger an out-of-bounds access via a crafted address     in an msi-x mmio operation.(CVE-2020-13754)

  - A heap-based buffer overflow was found in QEMU through     5.0.0 in the SDHCI device emulation support. It could     occur while doing a multi block SDMA transfer via the     sdhci_sdma_transfer_multi_blocks() routine in     hw/sd/sdhci.c. A guest user or process could use this     flaw to crash the QEMU process on the host, resulting     in a denial of service condition, or potentially     execute arbitrary code with privileges of the QEMU     process on the host. (CVE-2020-17380)

  - QEMU 5.0.0 has a heap-based Buffer Overflow in     flatview_read_continue in exec.c because hw/sd/sdhci.c     mishandles a write operation in the SDHC_BLKSIZE case.
    (CVE-2020-25085)

  - The patch for CVE-2020-17380/CVE-2020-25085 was found     to be ineffective, thus making QEMU vulnerable to the     out-of-bounds read/write access issues previously found     in the SDHCI controller emulation code. This flaw     allows a malicious privileged guest to crash the QEMU     process on the host, resulting in a denial of service     or potential code execution. QEMU up to (including)     5.2.0 is affected by this. (CVE-2021-3409)

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2021-9109 advisory.

  - iscsi_aio_ioctl_cb in block/iscsi.c in QEMU 4.1.0 has a heap-based buffer over-read that may disclose     unrelated information from process memory to an attacker. (CVE-2020-11947)

  - ide_atapi_cmd_reply_end in hw/ide/atapi.c in QEMU 5.1.0 allows out-of-bounds read access because a buffer     index is not validated. (CVE-2020-29443)

  - eth_get_gso_type in net/eth.c in QEMU 4.2.1 allows guest OS users to trigger an assertion failure. A guest     can crash the QEMU process via packet data that lacks a valid Layer 3 protocol. (CVE-2020-27617)

  - In QEMU 4.1.0, an out-of-bounds read flaw was found in the ATI VGA implementation. It occurs in the     ati_cursor_define() routine while handling MMIO write operations through the ati_mm_write() callback. A     malicious guest could abuse this flaw to crash the QEMU process, resulting in a denial of service.
    (CVE-2019-20808)

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

    (CVE-2019-20808)

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

According to the versions of the qemu packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - In QEMU through 5.0.0, an integer overflow was found in     the SM501 display driver implementation. This flaw     occurs in the COPY_AREA macro while handling MMIO write     operations through the sm501_2d_engine_write()     callback. A local attacker could abuse this flaw to     crash the QEMU process in sm501_2d_operation() in     hw/display/sm501.c on the host, resulting in a denial     of service.(CVE-2020-12829)

  - slirp.c in libslirp through 4.3.1 has a buffer     over-read because it tries to read a certain amount of     header data even if that exceeds the total packet     length.(CVE-2020-29130)

  - ncsi.c in libslirp through 4.3.1 has a buffer over-read     because it tries to read a certain amount of header     data even if that exceeds the total packet     length.(CVE-2020-29129)

  - hw/net/e1000e_core.c in QEMU 5.0.0 has an infinite loop     via an RX descriptor with a NULL buffer     address.(CVE-2020-28916)

  - ati_2d_blt in hw/display/ati_2d.c in QEMU 4.2.1 can     encounter an outside-limits situation in a calculation.
    A guest can crash the QEMU process.(CVE-2020-27616)

  - eth_get_gso_type in net/eth.c in QEMU 4.2.1 allows     guest OS users to trigger an assertion failure. A guest     can crash the QEMU process via packet data that lacks a     valid Layer 3 protocol.(CVE-2020-27617)

  - A reachable assertion issue was found in the USB EHCI     emulation code of QEMU. It could occur while processing     USB requests due to missing handling of DMA memory map     failure. A malicious privileged user within the guest     may abuse this flaw to send bogus USB requests and     crash the QEMU process on the host, resulting in a     denial of service.(CVE-2020-25723)

  - hw/usb/hcd-ohci.c in QEMU 5.0.0 has a stack-based     buffer over-read via values obtained from the host     controller driver.(CVE-2020-25624)

  - hw/usb/hcd-ohci.c in QEMU 5.0.0 has an infinite loop     when a TD list has a loop.(CVE-2020-25625)

  - In libslirp 4.1.0, as used in QEMU 4.2.0, tcp_subr.c     misuses snprintf return values, leading to a buffer     overflow in later code.(CVE-2020-8608)

  - tcp_emu in tcp_subr.c in libslirp 4.1.0, as used in     QEMU 4.2.0, mismanages memory, as demonstrated by IRC     DCC commands in EMU_IRC. This can cause a heap-based     buffer overflow or other out-of-bounds access which can     lead to a DoS or potential execute arbitrary     code.(CVE-2020-7039)

  - ip_reass in ip_input.c in libslirp 4.0.0 has a     heap-based buffer overflow via a large packet because     it mishandles a case involving the first     fragment.(CVE-2019-14378)

  - A flaw was found in the memory management API of QEMU     during the initialization of a memory region cache.
    This issue could lead to an out-of-bounds write access     to the MSI-X table while performing MMIO operations. A     guest user may abuse this flaw to crash the QEMU     process on the host, resulting in a denial of service.
    This flaw affects QEMU versions prior to     5.2.0.(CVE-2020-27821)

  - QEMU: reachable assertion failure in     net_tx_pkt_add_raw_fragment() in hw/net/net_tx_pkt.c     (CVE-2020-16092)

  - hw/pci/pci.c in QEMU 4.2.0 allows guest OS users to     trigger an out-of-bounds access by providing an address     near the end of the PCI configuration     space(CVE-2020-13791)

  - qmp_guest_file_read in qga/commands-posix.c and     qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent)     in QEMU 2.12.50 has an integer overflow causing a     g_malloc0() call to trigger a segmentation fault when     trying to allocate a large memory chunk. The     vulnerability can be exploited by sending a crafted QMP     command (including guest-file-read with a large count     value) to the agent via the listening     socket.(CVE-2018-12617)

  - sd_wp_addr in hw/sd/sd.c in QEMU 4.2.0 uses an     unvalidated address, which leads to an out-of-bounds     read during sdhci_write() operations. A guest OS user     can crash the QEMU process.(CVE-2020-13253)

  - QEMU 4.1.0 has a memory leak in zrle_compress_data in     ui/vnc-enc-zrle.c during a VNC disconnect operation     because libz is misused, resulting in a situation where     memory allocated in deflateInit2 is not freed in     deflateEnd.(CVE-2019-20382)

  - An integer overflow was found in QEMU 4.0.1 through     4.2.0 in the way it implemented ATI VGA emulation. This     flaw occurs in the ati_2d_blt() routine in     hw/display/ati-2d.c while handling MMIO write     operations through the ati_mm_write() callback. A     malicious guest could abuse this flaw to crash the QEMU     process, resulting in a denial of     service.(CVE-2020-11869)

  - This vulnerability has been modified since it was last     analyzed by the NVD. It is awaiting reanalysis which     may result in further changes to the information     provided.(CVE-2020-13659)

  - A flaw was found in QEMU in the implementation of the     Pointer Authentication (PAuth) support for ARM     introduced in version 4.0 and fixed in version 5.0.0. A     general failure of the signature generation process     caused every PAuth-enforced pointer to be signed with     the same signature. A local attacker could obtain the     signature of a protected pointer and abuse this flaw to     bypass PAuth protection for all programs running on     QEMU.(CVE-2020-10702)

  - hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU     before 07-20-2020 has a buffer overflow. This occurs     during packet transmission and affects the highbank and     midway emulated machines. A guest user or process could     use this flaw to crash the QEMU process on the host,     resulting in a denial of service or potential     privileged code execution. This was fixed in commit     5519724a13664b43e225ca05351c60b4468e4555.(CVE-2020-1586     3)

  - In QEMU 5.0.0 and earlier, megasas_lookup_frame in     hw/scsi/megasas.c has an out-of-bounds read via a     crafted reply_queue_head field from a guest OS     user.(CVE-2020-13362)

  - ** DISPUTED ** An issue was discovered in ide_dma_cb()     in hw/ide/core.c in QEMU 2.4.0 through 4.2.0. The guest     system can crash the QEMU process in the host system     via a special SCSI_IOCTL_SEND_COMMAND. It hits an     assertion that implies that the size of successful DMA     transfers there must be a multiple of 512 (the size of     a sector). NOTE: a member of the QEMU security team     disputes the significance of this issue because a     'privileged guest user has many ways to cause similar     DoS effect, without triggering this     assert.'(CVE-2019-20175)

  - In QEMU 5.0.0 and earlier, es1370_transfer_audio in     hw/audio/es1370.c does not properly validate the frame     count, which allows guest OS users to trigger an     out-of-bounds access during an es1370_write()     operation.(CVE-2020-13361)

  - rom_copy() in hw/core/loader.c in QEMU 4.1.0 does not     validate the relationship between two addresses, which     allows attackers to trigger an invalid memory copy     operation.(CVE-2020-13765)

  - libslirp 4.0.0, as used in QEMU 4.1.0, has a     use-after-free in ip_reass in     ip_input.c.(CVE-2019-15890)

  - A use after free vulnerability in ip_reass() in     ip_input.c of libslirp 4.2.0 and prior releases allows     crafted packets to cause a denial of     service.(CVE-2020-1983)

  - ati-vga in hw/display/ati.c in QEMU 4.2.0 allows guest     OS users to trigger infinite recursion via a crafted     mm_index value during an ati_mm_read or ati_mm_write     call.(CVE-2020-13800)

  - An out-of-bounds heap buffer access flaw was found in     the way the iSCSI Block driver in QEMU versions 2.12.0     before 4.2.1 handled a response coming from an iSCSI     server while checking the status of a Logical Address     Block (LBA) in an iscsi_co_block_status() routine. A     remote user could use this flaw to crash the QEMU     process, resulting in a denial of service or potential     execution of arbitrary code with privileges of the QEMU     process on the host.(CVE-2020-1711)

  - tftp.c in libslirp 4.1.0, as used in QEMU 4.2.0, does     not prevent ..\ directory traversal on     Windows.(CVE-2020-7211)

  - An out-of-bounds read vulnerability was found in the     SLiRP networking implementation of the QEMU emulator.
    This flaw occurs in the icmp6_send_echoreply() routine     while replying to an ICMP echo request, also known as     ping. This flaw allows a malicious guest to leak the     contents of the host memory, resulting in possible     information disclosure. This flaw affects versions of     libslirp before 4.3.1.(CVE-2020-10756)

According to the versions of the qemu packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - hw/ide/pci.c in QEMU before 5.1.1 can trigger a NULL     pointer dereference because it lacks a pointer check     before an ide_cancel_dma_sync call.(CVE-2020-25743)

  - pci_change_irq_level in hw/pci/pci.c in QEMU before     5.1.1 has a NULL pointer dereference because     pci_get_bus() might not return a valid     pointer.(CVE-2020-25742)

  - eth_get_gso_type in net/eth.c in QEMU 4.2.1 allows     guest OS users to trigger an assertion failure. A guest     can crash the QEMU process via packet data that lacks a     valid Layer 3 protocol.(CVE-2020-27617)

  - address_space_map in exec.c in QEMU 4.2.0 can trigger a     NULL pointer dereference related to     BounceBuffer.(CVE-2020-13659)

  - A reachable assertion issue was found in the USB EHCI     emulation code of QEMU. It could occur while processing     USB requests due to missing handling of DMA memory map     failure. A malicious privileged user within the guest     may abuse this flaw to send bogus USB requests and     crash the QEMU process on the host, resulting in a     denial of service.(CVE-2020-25723)

  - hw/usb/hcd-ohci.c in QEMU 5.0.0 has an infinite loop     when a TD list has a loop.(CVE-2020-25625)

  - In QEMU through 5.0.0, an assertion failure can occur     in the network packet processing. This issue affects     the e1000e and vmxnet3 network devices. A malicious     guest user/process could use this flaw to abort the     QEMU process on the host, resulting in a denial of     service condition in net_tx_pkt_add_raw_fragment in     hw/net/net_tx_pkt.c.(CVE-2020-16092)

  - In QEMU 5.0.0 and earlier, megasas_lookup_frame in     hw/scsi/megasas.c has an out-of-bounds read via a     crafted reply_queue_head field from a guest OS     user.(CVE-2020-13362)

  - The (1) v9fs_create and (2) v9fs_lcreate functions in     hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local     guest OS privileged users to cause a denial of service     (file descriptor or memory consumption) via vectors     related to an already in-use fid.(CVE-2017-7377)

  - In QEMU 5.0.0 and earlier, es1370_transfer_audio in     hw/audio/es1370.c does not properly validate the frame     count, which allows guest OS users to trigger an     out-of-bounds access during an es1370_write()     operation.(CVE-2020-13361)

  - hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU     before 07-20-2020 has a buffer overflow. This occurs     during packet transmission and affects the highbank and     midway emulated machines. A guest user or process could     use this flaw to crash the QEMU process on the host,     resulting in a denial of service or potential     privileged code execution. This was fixed in commit     5519724a13664b43e225ca05351c60b4468e4555.(CVE-2020-1586     3)

  - hw/usb/hcd-ohci.c in QEMU 5.0.0 has a stack-based     buffer over-read via values obtained from the host     controller driver.(CVE-2020-25624)

  - rom_copy() in hw/core/loader.c in QEMU 4.1.0 does not     validate the relationship between two addresses, which     allows attackers to trigger an invalid memory copy     operation.(CVE-2020-13765)

  - An out-of-bounds read/write access flaw was found in     the USB emulator of the QEMU in versions before 5.2.0.
    This issue occurs while processing USB packets from a     guest when USBDevice 'setup_len' exceeds its     'data_buf[4096]' in the do_token_in, do_token_out     routines. This flaw allows a guest user to crash the     QEMU process, resulting in a denial of service, or the     potential execution of arbitrary code with the     privileges of the QEMU process on the     host.(CVE-2020-14364)
