CVE-2018-3983 |
An exploitable uninitialized pointer vulnerability exists in the Word document parser of the the Atlantis Word Processor. A specially crafted document can cause an array fetch to return an uninitialized pointer and then performs some arithmetic before writing a value to the result. Usage of this uninitialized pointer can allow an attacker to corrupt heap memory resulting in code execution under the context of the application. An attacker must convince a victim to open a document in order to trigger this vulnerability. Published: October 31, 2019; 5:15:12 PM -0400 |
V4.0:(not available) V3.1: 7.8 HIGH V2.0: 6.8 MEDIUM |
CVE-2018-3984 |
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. Published: October 01, 2018; 4:29:01 PM -0400 |

CVE-2018-3982 |
An exploitable arbitrary write vulnerability exists in the Word document parser of the Atlantis Word Processor 3.0.2.3 and 3.0.2.5. A specially crafted document can prevent Atlas from adding elements to an array that is indexed by a loop. When reading from this array, the application will use an out-of-bounds index which can result in arbitrary data being read as a pointer. Later, when the application attempts to write to said pointer, an arbitrary write will occur. This can allow an attacker to further corrupt memory, which leads 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. Published: October 01, 2018; 4:29:00 PM -0400 |

CVE-2018-3978 |
An exploitable out-of-bounds write vulnerability exists in the Word Document parser of the Atlantis Word Processor 3.0.2.3, 3.0.2.5. A specially crafted document can cause Atlantis to write a value outside the bounds of a heap allocation, resulting in a buffer overflow. An attacker must convince a victim to open a document in order to trigger this vulnerability. Published: October 01, 2018; 4:29:00 PM -0400 |
