CVE-2021-31343: Siemens Solid Edge Viewer DFT File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability
The jutil.dll library in all versions of Solid Edge SE2020 before 2020MP14 and all versions of Solid Edge SE2021 before SE2021MP5 lack proper validation of user-supplied data when parsing DFT files. This could result in an out-of-bounds write past the end of an allocation structure. An attacker could leverage this vulnerability to execute code in the context of the current process.
