Wyse ThinOS HF 4.4.079i has a buffer overflow vulnerability in the LPD service (515/tcp).
The LPD service (515/tcp) on Wyse ThinOS HF 4.4.079i crashes when a long buffer is sent to it. This condition may exist in all versions before Wyse ThinOS 6.5.
An attacker can cause the device to crash and may be able to execute arbitrary code.
The vendor recommends users upgrade to Wyse ThinOS 6.5 or newer.
Enable firewall rules to restrict access for port 515/tcp to only trusted sources.
