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

  - Buffer overflow in the pxa2xx_ssp_load function in
    hw/arm/pxa2xx.c in QEMU before 1.7.2 allows remote
    attackers to cause a denial of service or possibly
    execute arbitrary code via a crafted s-i1/4zrx_level
    value in a savevm image.(CVE-2013-4533)

  - Multiple buffer overflows in the ssd0323_load function
    in hw/display/ssd0323.c in QEMU before 1.7.2 allow
    remote attackers to cause a denial of service (memory
    corruption) or possibly execute arbitrary code via
    crafted (1) cmd_len, (2) row, or (3) col values (4)
    row_start and row_end values or (5) col_star and
    col_end values in a savevm image.(CVE-2013-4538)

  - The ssi_sd_transfer function in hw/sd/ssi-sd.c in QEMU
    before 1.7.2 allows remote attackers to execute
    arbitrary code via a crafted arglen value in a savevm
    image.(CVE-2013-4537)

  - Buffer overflow in hw/intc/openpic.c in QEMU before
    1.7.2 allows remote attackers to cause a denial of
    service or possibly execute arbitrary code via vectors
    related to IRQDest elements.(CVE-2013-4534)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
