Affected applications lack proper validation of user-supplied data when parsing CGM files. This could lead to a stack based buffer overflow while trying to copy to a buffer in the font index handling function. An attacker could leverage this vulnerability to execute code in the context of the current process.","published":"2021-01-12T21:15:17.000Z","lastModified":"2026-06-17T03:08:41.000Z","status":"Modified","sourceIdentifier":"productcert@siemens.com","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-121","CWE-787"],"affected":["siemens/jt2go","siemens/teamcenter visualization"],"epss":{"score":0.0165,"percentile":0.76347,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.65%).
