What an attacker can do

The source says when a crafted Zip64 entry declares an uncompressed size from 2^63 through 2^64-1 and the workbook is opened, the negative size bypasses unzip limits and reaches make as a negative capacity, allowing an attacker to panic during workbook opening. Vendor/CNA’s CVSS 3.1 assessment (base score 6.5/10) rates confidentiality and integrity impact as none; availability impact as high.
