medium Nessus Plugin ID 370991

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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. (CVE-2026-115484)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution
