CVE-2020-5344
Dell EMC iDRAC7, iDRAC8 and iDRAC9 versions prior to 2.65.65.65, 2.70.70.70, 4.00.00.00 contain a stack-based buffer overflow vulnerability. An unauthenticated remote attacker may exploit this vulnerability to crash the affected process or execute arbitrary code on the system by sending specially crafted input data.
Affected versions (NVD)
| Product | Versions |
|---|---|
| idrac7_firmware | < 2.65.65.65 |
| idrac8_firmware | < 2.70.70.70 |
| idrac9_firmware | < 4.00.00.00 |
What to do
NVD marks firmware before these versions as affected: idrac7_firmware before 2.65.65.65; idrac8_firmware before 2.70.70.70; idrac9_firmware before 4.00.00.00. The usual fix is to update to that version or later. Vendors patch each firmware branch separately, so confirm the fixed build for your branch in the advisory.
