What is CVE-2021-31342?

The vulnerability in the ugeom2d.dll library present in Solid Edge versions 2020 and 2021 occurs due to insufficient validation of user-supplied data during the parsing of DFT files. An attacker who successfully exploits this flaw could potentially perform an out-of-bounds write, allowing them to execute arbitrary code in the context of the affected process.
