CWE-670
Always-Incorrect Control Flow Implementation
The code contains a control flow path that does not reflect the algorithm that the path is intended to implement, leading to incorrect behavior any time this path is navigated.

- CWE-670 - Always-Incorrect Control Flow Implementation, CWE-1119: Excessive Use of Unconditional Branching
Summary
A logic vulnerability when handling the SaveGeneratorLong instruction in Facebook Hermes prior to commit b2021df620824627f5a8c96615edbd1eb7fdddfc allows attackers to potentially read out of bounds or theoretically execute arbitrary code via crafted JavaScript. Note that this is only exploitable if the application using Hermes permits evaluation of untrusted JavaScript. Hence, most React Native applications are not affected.

Summary
An always-incorrect control flow implementation in the implicit filter terms of Juniper Networks Junos OS and Junos OS Evolved on ACX5800, EX9200 Series, MX10000 Series, MX240, MX480, MX960 devices with affected Trio line cards allows an attacker to exploit an interdependency in the PFE UCODE microcode of the Trio chipset with various line cards to cause packets destined to the devices interfaces to cause a Denial of Service (DoS) condition by looping the packet with an unreachable exit condition ('Infinite Loop'). To break this loop once it begins one side of the affected LT interfaces will need to be disabled. Once disabled, the condition will clear and the disabled LT interface can be reenabled. Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition. This issue only affects LT-LT interfaces. Any other interfaces are not affected by this issue. This issue affects the following cards: MPCE Type 3 3D MPC4E 3D 32XGE MPC4E 3D 2CGE+8XGE EX9200 32x10G SFP EX9200-2C-8XS FPC Type 5-3D FPC Type 5-LSR EX9200 4x40G QSFP An Indicator of Compromise (IoC) can be seen by examining the traffic of the LT-LT interfaces for excessive traffic using the following command: monitor interface traffic Before loop impact: Interface: lt-2/0/0, Enabled, Link is Up Encapsulation: Logical-tunnel, Speed: 100000mbps Traffic statistics: Current delta Input bytes: 3759900268942 (1456 bps) [0] <---------- LT interface utilization is low Output bytes: 3759900344309 (1456 bps) [0] <---------- LT interface utilization is low After loop impact: Interface: lt-2/0/0, Enabled, Link is Up Encapsulation: Logical-tunnel, Speed: 100000mbps Traffic statistics: Current delta Input bytes: 3765160313129 (2158268368 bps) [5260044187] <---------- LT interface utilization is very high Output bytes: 3765160399522 (2158266440 bps) [5260055213] <---------- LT interface utilization is very high This issue affects: Juniper Networks Junos OS on ACX5800, EX9200 Series, MX10000 Series, MX240, MX480, MX960.

Summary
Multiple Cisco products are affected by a vulnerability in the Snort application detection engine that could allow an unauthenticated, remote attacker to bypass the configured policies on an affected system. The vulnerability is due to a flaw in the detection algorithm. An attacker could exploit this vulnerability by sending crafted packets that would flow through an affected system. A successful exploit could allow the attacker to bypass the configured policies and deliver a malicious payload to the protected network.

Summary
magento-scripts contains scripts and configuration used by Create Magento App, a zero-configuration tool-chain which allows one to deploy Magento 2. In versions 1.5.1 and 1.5.2, after changing the function from synchronous to asynchronous there wasn't implemented handler in the start, stop, exec, and logs commands, effectively making them unusable. Version 1.5.3 contains patches for the problems.

Summary
A vulnerability in IPv6 traffic processing of Cisco IOS XE Wireless Controller Software for Cisco Catalyst 9000 Family Wireless Controllers could allow an unauthenticated, adjacent attacker to cause a Layer 2 (L2) loop in a configured VLAN, resulting in a denial of service (DoS) condition for that VLAN. The vulnerability is due to a logic error when processing specific link-local IPv6 traffic. An attacker could exploit this vulnerability by sending a crafted IPv6 packet that would flow inbound through the wired interface of an affected device. A successful exploit could allow the attacker to cause traffic drops in the affected VLAN, thus triggering the DoS condition.

Summary
The evm crate is a pure Rust implementation of Ethereum Virtual Machine. In `evm` crate `< 0.31.0`, `JUMPI` opcode's condition is checked after the destination validity check. However, according to Geth and OpenEthereum, the condition check should happen before the destination validity check. This is a **high** severity security advisory if you use `evm` crate for Ethereum mainnet. In this case, you should update your library dependency immediately to on or after `0.31.0`. This is a **low** severity security advisory if you use `evm` crate in Frontier or in a standalone blockchain, because there's no security exploit possible with this advisory. It is **not** recommended to update to on or after `0.31.0` until all the normal chain upgrade preparations have been done. If you use Frontier or other `pallet-evm` based Substrate blockchain, please ensure to update your `spec_version` before updating this. For other blockchains, please make sure to follow a hard-fork process before you update this.

Summary
Stargate-Bukkit is a mod for the minecraft video game which adds a portal focused environment. In affected versions Minecarts with chests will drop their items when teleporting through a portal; when they reappear, they will still have their items impacting the integrity of the game world. The teleport code has since been rewritten and is available in release `0.11.5.1`. Users are advised to upgrade. There are no known workarounds for this issue.

Summary
Cronos is a commercial implementation of a blockchain. In Cronos nodes running versions before v0.6.5, it is possible to take transaction fees from Cosmos SDK's FeeCollector for the current block by sending a custom crafted MsgEthereumTx. This problem has been patched in Cronos v0.6.5. There are no tested workarounds. All validator node operators are recommended to upgrade to Cronos v0.6.5 at their earliest possible convenience.

- CWE-670 - Always-Incorrect Control Flow Implementation
Summary
Envoy is an open source edge and service proxy, designed for cloud-native applications. The envoy common router will segfault if an internal redirect selects a route configured with direct response or redirect actions. This will result in a denial of service. As a workaround turn off internal redirects if direct response entries are configured on the same listener.

- CWE-670 - Always-Incorrect Control Flow Implementation
Summary
Istio is an open platform to connect, manage, and secure microservices. In Istio 1.12.0 and 1.12.1 The authorization policy with hosts and notHosts might be accidentally bypassed for ALLOW action or rejected unexpectedly for DENY action during the upgrade from 1.11 to 1.12.0/1.12.1. Istio 1.12 supports the hosts and notHosts fields in authorization policy with a new Envoy API shipped with the 1.12 data plane. A bug in the 1.12.0 and 1.12.1 incorrectly uses the new Envoy API with the 1.11 data plane. This will cause the hosts and notHosts fields to be always matched regardless of the actual value of the host header when mixing 1.12.0/1.12.1 control plane and 1.11 data plane. Users are advised to upgrade or to not mix the 1.12.0/1.12.1 control plane with 1.11 data plane if using hosts or notHosts field in authorization policy.
