HIGH 8.8EPSS 2.50%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.50%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
