Noroxi assessment
Priority: Monitor (action score 32/100)
- Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 40.4% (FIRST EPSS); higher than 98.6% of all records.
- Special conditions such as timing or configuration are required.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
Buffer overflow in LsCreateLine function (mso_203) in mso.dll and mso9.dll, as used by Microsoft Word and possibly other products in Microsoft Office 2003, 2002, and 2000, allows remote user-assisted attackers to cause a denial of service (crash) via a crafted Word DOC or other Office file type. NOTE: this issue was originally reported to allow code execution, but on 20060710 Microsoft stated that code execution is not possible, and the original researcher agrees.
