Kerentanan Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') pada apache openoffice. Skor CVSS 3.1 7.8 (High) menurut NVD.

Deskripsi (NVD)

Apache OpenOffice opens dBase/DBF documents and shows the contents as spreadsheets. DBF are database files with data organized in fields. When reading DBF data the size of certain fields is not checked: the data is just copied into local variables. A carefully crafted document could overflow the allocated space, leading to the execution of arbitrary code by altering the contents of the program stack. This issue affects Apache OpenOffice up to and including version 4.1.10
