CVE-2020-13544
Last modified
CVE-2020-13544 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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. EPSS estimates a 1.58% chance of exploitation in the next 30 days.
