"According to the versions of the zziplib package installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - An issue was discovered in ZZIPlib through 0.13.69.
    There is a memory leak triggered in the function
    __zzip_parse_root_directory in zip.c, which will lead
    to a denial of service attack.(CVE-2018-16548)

  - Heap-based buffer overflow in the __zzip_get32 function
    in fetch.c in zziplib 0.13.62 allows remote attackers
    to cause a denial of service (crash) via a crafted ZIP
    file.(CVE-2017-5974)

  - Heap-based buffer overflow in the __zzip_get64 function
    in fetch.c in zziplib 0.13.62 allows remote attackers
    to cause a denial of service (crash) via a crafted ZIP
    file.(CVE-2017-5975)

  - Heap-based buffer overflow in the
    zzip_mem_entry_extra_block function in memdisk.c in
    zziplib 0.13.62 allows remote attackers to cause a
    denial of service (crash) via a crafted ZIP
    file.(CVE-2017-5976)

  - In ZZIPlib 0.13.67, there is a bus error caused by
    loading of a misaligned address (when handling
    disk64_trailer local entries) in
    __zzip_fetch_disk_trailer (zzip/zip.c). Remote
    attackers could leverage this vulnerability to cause a
    denial of service via a crafted zip
    file.(CVE-2018-6541)

  - In ZZIPlib 0.13.67, there is a bus error caused by
    loading of a misaligned address in the
    zzip_disk_findfirst function of zzip/mmapped.c. Remote
    attackers could leverage this vulnerability to cause a
    denial of service via a crafted zip
    file.(CVE-2018-6540)

  - In ZZIPlib 0.13.67, there is a memory alignment error
    and bus error in the __zzip_fetch_disk_trailer function
    of zzip/zip.c. Remote attackers could leverage this
    vulnerability to cause a denial of service via a
    crafted zip file.(CVE-2018-6484)

  - In ZZIPlib 0.13.67, there is a segmentation fault
    caused by invalid memory access in the zzip_disk_fread
    function (zzip/mmapped.c) because the size variable is
    not validated against the amount of file->stored
    data.(CVE-2018-6381)

  - In ZZIPlib 0.13.68, there is an uncontrolled memory
    allocation and a crash in the
    __zzip_parse_root_directory function of zzip/zip.c.
    Remote attackers could leverage this vulnerability to
    cause a denial of service via a crafted zip
    file.(CVE-2018-6869)

  - seeko.c in zziplib 0.13.62 allows remote attackers to
    cause a denial of service (assertion failure and crash)
    via a crafted ZIP file.(CVE-2017-5981)

  - The prescan_entry function in fseeko.c in zziplib
    0.13.62 allows remote attackers to cause a denial of
    service (NULL pointer dereference and crash) via a
    crafted ZIP file.(CVE-2017-5979)

  - The zzip_mem_entry_extra_block function in memdisk.c in
    zziplib 0.13.62 allows remote attackers to cause a
    denial of service (invalid memory read and crash) via a
    crafted ZIP file.(CVE-2017-5977)

  - The zzip_mem_entry_new function in memdisk.c in zziplib
    0.13.62 allows remote attackers to cause a denial of
    service (out-of-bounds read and crash) via a crafted
    ZIP file.(CVE-2017-5978)
