CVE-2018-17828

Directory traversal vulnerability in ZZIPlib 0.13.69 allows attackers to overwrite arbitrary files via a .. (dot dot) in a zip file, because of the function unzzip_cat in the bins/unzzipcat-mem.c file.

Directory traversal vulnerability in ZZIPlib 0.13.69 allows attackers to overwrite arbitrary files via a .. (dot dot) in a zip file, because of the function unzzip_cat in the bins/unzzipcat-mem.c file.

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).

An unaligned memory access bug was found in the way ZZIPlib handled ZIP files. This flaw could potentially be used to crash the application using ZZIPlib by tricking the application into processing specially crafted ZIP files (CVE-2018-6484).

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).

A flaw was found 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 (when handling a disk64_trailer seek value) caused by loading of a misaligned address in the zzip_disk_findfirst function of zzip/mmapped.c (CVE-2018-6542).

An uncontrolled memory allocation was found in ZZIPlib that could lead to a crash in the __zzip_parse_root_directory function of zzip/zip.c if the package is compiled with Address Sanitizer. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file (CVE-2018-6869).

An out of bounds read was found in function zzip_disk_fread of ZZIPlib, up to 0.13.68, when ZZIPlib mem_disk functionality is used. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file (CVE-2018-7725).

An improper input validation was found in function __zzip_fetch_disk_trailer of ZZIPlib, up to 0.13.68, that could lead to a crash in __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-2018-7726).

A memory leak was found in unzip-mem.c and unzzip-mem.c of ZZIPlib, up to v0.13.68, that could lead to resource exhaustion. Local attackers could leverage this vulnerability to cause a denial of service via a crafted zip file (CVE-2018-7727).

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 could lead to a denial of service attack (CVE-2018-16548).

A flaw was found in ZZIPlib 0.13.69. A directory traversal vulnerability allows attackers to overwrite arbitrary files via a .. (dot dot) in a zip file, because of the function unzzip_cat in the bins/unzzipcat-mem.c file (CVE-2018-17828).

These are all security issues fixed in the libzzip-0-13-0.13.72-1.4 package on the GA media of openSUSE Tumbleweed.

This update for zziplib fixes the following issues:

• CVE-2018-17828: Remove any '../' components from pathnames of extracted files to avoid path traversal during unpacking. (bsc#1110687)
