CVE-2010-3843

The gtkui_conf_read function in src/interfaces/gtk/ec_gtk_conf.c in Ettercap 0.7.3, when the GTK interface is used, does not ensure that the contents of the .ettercap_gtk file are controlled by the root user, which allows local users to conduct stack-based buffer overflow attacks and possibly execute arbitrary code, cause a denial of service (memory consumption), or possibly have unspecified other impact via crafted lines in this file.

CVE-2019-14821

An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel’s KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer ‘struct kvm_coalesced_mmio’ object, wherein write indices ‘ring->first’ and ‘ring->last’ value could be supplied by a host user-space process. An unprivileged host user or process with access to ‘/dev/kvm’ device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system.

CVE-2021-20206

An improper limitation of path name flaw was found in containernetworking/cni in versions before 0.8.1. When specifying the plugin to load in the ‘type’ field in the network configuration, it is possible to use special elements such as “../” separators to reference binaries elsewhere on the system. This flaw allows an attacker to execute other existing binaries other than the cni plugins/types, such as ‘reboot’. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
