CVE-2017-18258 (opens in a new tab)How to fix?
There is no fixed version for Centos:8 mingw64-libxml2.
NVD Description
Note: Versions mentioned in the description apply only to the upstream mingw64-libxml2 package and not the mingw64-libxml2 package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
The xz_head function in xzlib.c in libxml2 before 2.9.6 allows remote attackers to cause a denial of service (memory consumption) via a crafted LZMA file, because the decoder functionality does not restrict memory usage to what is required for a legitimate file.
