Short explanation
A stack-based buffer overflow vulnerability in the jdhcpd process of Juniper Networks Junos OS and Junos OS Evolved platforms occurs when the DHCPv4 local-client feature is used. This vulnerability allows an adjacent unauthenticated attacker to cause a denial of service or execute arbitrary code with root privileges via a malformed DHCPv4 server response.
This vulnerability poses a high risk because an adjacent network attacker can execute arbitrary code with root privileges or cause a service disruption on vulnerable systems. It presents potential exploitation risks in environments where the DHCPv4 local-client feature is enabled.
What should be done?
- Follow official vendor advisories.
- Review DHCPv4 local-client configurations on affected platforms.
- Apply guidance specified in the vendor advisory.
