Technical Description
An exploitable integer overflow vulnerability exists in the PlanMaker document parsing functionality of SoftMaker Office 2021’s PlanMaker application. A specially crafted document can cause the document parser perform arithmetic that may overflow which can result in an undersized heap allocation. Later when copying data from the file into this allocation, a heap-based buffer overflow will occur which can corrupt memory. These types of memory corruptions can allow for code execution under the context of the application. An attacker can entice the victim to open a document to trigger this vulnerability.
Remediation
Check the references section for vendor advisories and patches from softmaker. Update planmaker_2021 to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
