Cisco Talos researchers exposed multiple vulnerabilities in SoftMaker Office TextMaker that can be exploited by cyber attackers. These vulnerabilities in SoftMaker office can be exploited for arbitrary code execution by generating malicious documents and deceiving victims into opening them. 

SoftMaker Office TextMaker is a German-based software developer; it has various suites like a spreadsheet, word processing, presentation, and database software components, and all these well-liked software suites are presented to individuals and enterprises. The common and internal document file formats also acquire the support of the SoftMaker office suite. 
The foremost issue is a sign extension bug, CVE-2020-13544 which influences the document-analyzing functionality of SoftMaker Office TextMaker 2021 and the subsequent vulnerability has been traced as CVE-2020-13545 which is a sign altering flaw in the same document-analyzing of the application. 
Cisco Talos researchers illustrated that “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”. A heap-based memory can be corrupted by an attacker who can adeptly design a document which can lead to the document analyzer. 
The document analyzer can misjudge the length while assigning a buffer which will lead the application to be written outside the bounds of the buffer. Traced as CVE-2020-13546, the flaw is detected to affect the SoftMaker Office 2021 by integer overflow susceptibility. 
SoftMaker office 2021 was evaluated with a Common Vulnerability Scoring System (CVSS) of 8.8 and now all three vulnerabilities are secured. The most threatening issue was that the attacker can exploit the loophole in the SoftMaker office in 2021 from any remote location.
