A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure.

A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds read by setting the size fields with a value beyond the array boundaries, leading to a crash or information disclosure.

Kibana versions prior to 7.6.3 suffer from a prototype pollution bug within the Upgrade Assistant. By setting a new constructor.prototype.sourceURL value you can execute arbitrary code. Code execution is possible through two different ways. Either by sending data directly to Elastic, or using Kibana to submit the same queries. Either method enters the polluted prototype for Kibana to read. Kibana will either need to be restarted, or collection happens (unknown time) for the payload to execute. Once it does, cleanup must delete the .kibana_1 index for Kibana to restart successfully. Once a callback does occur, cleanup will happen allowing Kibana to be successfully restarted on next attempt.

Simple Packet Sender (SPS) is a Linux packet crafting tool. It supports IPv4, IPv6 (but not extension headers yet), and tunneling IPv6 over IPv4. Written in C on Linux with GUI built using GTK+. Both source and binaries are included. Features include packet crafting and sending one, multiple, or flooding packets of type TCP, ICMP, or UDP. All values within ethernet frame can be modified arbitrarily. Supports TCP, ICMP and UDP data as well, with input from either keyboard as UTF-8/ASCII, keyboard as hexadecimal, or from file. Various other features exist as well.
