What fixes it

No source in this snapshot names a fixed version. The vendor advisories under References are the place to check.

Description

A flaw was found in the iscsiuio component of open-iscsi. The DHCPv4 option parser incorrectly calculates the length of the options data, causing it to read beyond the allocated buffer into adjacent heap memory. An attacker on the same network segment can send a crafted DHCP response to crash the daemon or corrupt its network configuration.
