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

"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 0.13.68. An invalid
    memory address dereference was discovered in
    zzip_disk_fread in mmapped.c. The vulnerability causes
    an application crash, which leads to denial of
    service.(CVE-2018-7725 )

  - An issue was discovered in ZZIPlib 0.13.68. There is a
    bus error caused by the __zzip_parse_root_directory
    function of zip.c. Attackers could leverage this
    vulnerability to cause a denial of service via a
    crafted zip file.(CVE-2018-7726)

  - An issue was discovered in ZZIPlib 0.13.68. There is a
    memory leak triggered in the function zzip_mem_disk_new
    in memdisk.c, which will lead to a denial of service
    attack.(CVE-2018-7727)

  - 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)

  - 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)
