CVE-2020-4433
Certain IBM Aspera applications are vulnerable to a stack-based buffer overflow, caused by improper bounds checking.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.26%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
