Open-iscsi: open-iscsi: dhcpv6 vendor option strlen heap out-of-bounds read and 1-byte write in iscsiuio PUBLISHED

Description (CNA)

A flaw was found in the iscsiuio component of open-iscsi. The DHCPv6 option parser calls strlen() on raw network data without ensuring a NUL terminator is present, causing it to read past the buffer into heap memory. This can result in a daemon crash, a 1-byte heap overwrite, or corruption of the iSCSI initiator name. An attacker on the same network segment can trigger this by sending a crafted DHCPv6 Advertise message.
