The remote SUSE Linux SLES11 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:14704-1 advisory.

  - The vmware-vga driver (hw/display/vmware_vga.c) in QEMU allows local guest users to write to qemu memory     locations and gain privileges via unspecified parameters related to rectangle handling. (CVE-2014-3689)

  - The VNC websocket frame decoder in QEMU allows remote attackers to cause a denial of service (memory and     CPU consumption) via a large (1) websocket payload or (2) HTTP headers section. (CVE-2015-1779)

  - 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)

  - 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)

  - rom_copy() in hw/core/loader.c in QEMU 4.0 and 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)

  - QEMU 5.0.0 has a use-after-free in hw/usb/hcd-xhci.c because the usb_packet_map return value is not     checked. (CVE-2020-25084)

  - 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)

  - 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)

  - 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)

  - 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)

  - A race condition flaw was found in the 9pfs server implementation of QEMU up to and including 5.2.0. This     flaw allows a malicious 9p client to cause a use-after-free error, potentially escalating their privileges     on the system. The highest threat from this vulnerability is to confidentiality, integrity as well as     system availability. (CVE-2021-20181)

  - 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)

  - ** 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)
