Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

Verint 5620PTZ Verint_FW_0_42 and Verint 4320 V4320_FW_0_23, and V4320_FW_0_31 units feature an autodiscovery service implemented in the binary executable '/usr/sbin/DM' that listens on port TCP 6666. The service is vulnerable to a stack buffer overflow. It is worth noting that this service does not require any authentication.
