of a buffer. The simplest type of error, and the most common cause of buffer overflows, is the \"classic\" case in which the product copies the buffer without restricting how much is copied. Other variants exist, but the existence of a classic overflow strongly suggests that the programmer is not considering even the most basic of security protections.","Incomplete",2,false,[],{"title":126,"metaDescription":127,"keywords":128,"canonicalUrl":129,"structuredData":130},"What is CVE-2020-27818?
