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.

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2019-2196 advisory.

  - 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)

  - 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several issues have been fixed in zziplib, a library providing read access on ZIP-archives. They are basically all related to invalid memory access and resulting crash or memory leak.

For Debian 8 'Jessie', these problems have been fixed in version 0.13.62-3+deb8u2.

We recommend that you upgrade your zziplib packages.

NIST reports (by search in the range 2017/01/01 - 2018/07/06) :

17 security fixes in this release :

- Heap-based buffer overflow in the __zzip_get32 function in fetch.c.

- Heap-based buffer overflow in the __zzip_get64 function in fetch.c.

- Heap-based buffer overflow in the zzip_mem_entry_extra_block function in memdisk.c.

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

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

- The zzip_mem_entry_new function in memdisk.c cause a NULL pointer dereference and crash via a crafted ZIP file.

- seeko.c cause a denial of service (assertion failure and crash) via a crafted ZIP file.

- A segmentation fault caused by invalid memory access in the zzip_disk_fread function because the size variable is not validated against the amount of file->stored data.

- A memory alignment error and bus error in the
__zzip_fetch_disk_trailer function of zzip/zip.c.

- A bus error caused by loading of a misaligned address in the zzip_disk_findfirst function.

- An uncontrolled memory allocation and a crash in the
__zzip_parse_root_directory function.

- An invalid memory address dereference was discovered in zzip_disk_fread in mmapped.c.

- A memory leak triggered in the function zzip_mem_disk_new in memdisk.c.

It was discovered that zziplib incorrectly handled certain malformed ZIP files. If a user or automated system were tricked into opening a specially crafted ZIP file, a remote attacker could cause zziplib to crash, resulting in a denial of service, or possibly execute arbitrary code.
