Detailsinfo

A vulnerability has been found in Atlantis Word Processor 3.0.2.3/3.0.2.5 and classified as critical. Affected by this vulnerability is an unknown function of the component Word Document Parser. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The bug was discovered 10/01/2018. The weakness was presented 10/01/2018 by Tyler Bohan with Cisco Talos (Website). It is possible to read the advisory at talosintelligence.com.
