What is CVE-2018-3984?
CVE-2018-3984 is a high-severity memory corruption vulnerability in The Atlantis Word Processor Team Atlantis Word Processor, published on 1 Oct 2018. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
An exploitable uninitialized length vulnerability exists within the Word document-parser of the Atlantis Word Processor 3.0.2.3 and 3.0.2.5. A specially crafted document can cause Atlantis to skip initializing a value representing the number of columns of a table. Later, the application will use this as a length within a loop that will write to a pointer on the heap. Due to this value being controlled, a buffer overflow will occur, which can lead to code execution under the context of the application. An attacker must convince a victim to open a document in order to trigger this vulnerability.
