CVE-2020-13544 (GCVE-0-2020-13544)

Vulnerability from cvelistv5 – Published: 2021-01-06 14:48 – Updated: 2024-08-04 12:18

Summary

An exploitable sign extension vulnerability exists in the TextMaker document parsing functionality of SoftMaker Office 2021’s TextMaker application. A specially crafted document can cause the document parser to sign-extend a length used to terminate a loop, which can later result in the loop’s index being used to write outside the bounds of a heap buffer during the reading of file data. An attacker can entice the victim to open a document to trigger this vulnerability.

Severity

8.8 (High)
