The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

This update for zziplib fixes the following issues :

Security issues fixed :

CVE-2018-16548: Avoid a memory leak from __zzip_parse_root_directory() which could lead to denial of service. (bsc#1107424)

CVE-2018-7727: Fixed a memory leak in unzzip_cat() (bsc#1084515).

Non-security issue fixed: Prevented division by zero by first checking if uncompressed size is 0. This may happen with directories which have a compressed and uncompressed size of 0. (bsc#1129403)

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)
