An Improper Input Validation vulnerability in the Packet Forwarding Engine of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause memory leak, leading to Denial of Service (DoS). On all Junos OS QFX5000 Series platforms, when pseudo-VTEP (Virtual Tunnel End Point) is configured under EVPN-VXLAN scenario, and specific DHCP packets are transmitted, DMA memory leak is observed. Continuous receipt of these specific DHCP packets will cause memory leak to reach 99% and then cause the protocols to stop working and traffic is impacted, leading to Denial of Service (DoS) condition. A manual reboot of the system recovers from the memory leak. To confirm the memory leak, monitor for "sheaf:possible leak" and "vtep not found" messages in the logs. This issue affects: Juniper Networks Junos OS QFX5000 Series: * All versions prior to 20.4R3-S6; * 21.1 versions prior to 21.1R3-S5; * 21.2 versions prior to 21.2R3-S5; * 21.3 versions prior to 21.3R3-S4; * 21.4 versions prior to 21.4R3-S3; * 22.1 versions prior to 22.1R3-S2; * 22.2 versions prior to 22.2R2-S2, 22.2R3; * 22.3 versions prior to 22.3R2-S1, 22.3R3; * 22.4 versions prior to 22.4R1-S2, 22.4R2.

An Improper Input Validation vulnerability in the routing protocol daemon (rpd) of Juniper Networks allows an attacker to cause a Denial of Service (DoS )to the device upon receiving and processing a specific malformed ISO VPN BGP UPDATE packet. Continued receipt of this packet will cause a sustained Denial of Service condition. This issue affects: * Juniper Networks Junos OS: * All versions prior to 20.4R3-S6; * 21.1 versions prior to 21.1R3-S5; * 21.2 versions prior to 21.2R3-S4; * 21.3 versions prior to 21.3R3-S3; * 21.4 versions prior to 21.4R3-S3; * 22.1 versions prior to 22.1R2-S2, 22.1R3; * 22.2 versions prior to 22.2R2-S1, 22.2R3; * 22.3 versions prior to 22.3R1-S2, 22.3R2.

An Improper Input Validation vulnerability in the VxLAN packet forwarding engine (PFE) of Juniper Networks Junos OS on QFX5000 Series, EX4600 Series devices allows an unauthenticated, adjacent attacker, sending two or more genuine packets in the same VxLAN topology to possibly cause a DMA memory leak to occur under various specific operational conditions. The scenario described here is the worst-case scenario. There are other scenarios that require operator action to occur. An indicator of compromise may be seen when multiple devices indicate that FPC0 has gone missing when issuing a show chassis fpc command for about 10 to 20 minutes, and a number of interfaces have also gone missing. Use the following command to determine if FPC0 has gone missing from the device. show chassis fpc detail This issue affects: Juniper Networks Junos OS on QFX5000 Series, EX4600 Series: * 18.4 version 18.4R2 and later versions prior to 20.4R3-S8; * 21.1 version 21.1R1 and later versions prior to 21.2R3-S6; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3-S4; * 22.1 versions prior to 22.1R3-S3; * 22.2 versions prior to 22.2R3-S1; * 22.3 versions prior to 22.3R2-S2, 22.3R3; * 22.4 versions prior to 22.4R2.

Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a single request as multiple requests leading to the possibility of request smuggling when behind a reverse proxy. Older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fix the issue.Show less

Hydra is the two-layer scalability solution for Cardano. Prior to version 0.13.0, it is possible for a malicious head initializer to extract one or more PTs for the head they are initializing due to incorrect data validation logic in the head token minting policy which then results in an flawed check for burning the head ST in the `initial` validator. This is possible because it is not checked in `HeadTokens.hs` that the datums of the outputs at the `initial` validator are equal to the real head ID, and it is also not checked in the `off-chain code`. During the `Initial` state of the protocol, if the malicious initializer removes a PT from the Hydra scripts it becomes impossible for any other participant to reclaim any funds they have attempted to commit into the head, as to do so the Abort transaction must burn all the PTs for the head, but they cannot burn the PT which the attacker controls and so cannot satisfy this requirement. That means the initializer can lock the other participants committed funds forever or until they choose to return the PT (ransom). The malicious initializer can also use the PT to spoof that they have committed a particular TxO when progressing the head into the `Open` state. For example, they could say they committed a TxO residing at their address containing 100 ADA, but in fact this 100 ADA was not moved into the head, and thus in order for an other participant to perform the fanout they will be forced to pay the attacker the 100 ADA out of their own funds, as the fanout transaction must pay all the committed TxOs (even though the attacker did not really commit that TxO). They can do this by placing the PT in a UTxO with a well-formed `Commit` datum with whatever contents they like, then use this UTxO in the `collectCom` transaction. There may be other possible ways to abuse having control of a PT. Version 0.13.0 fixes this issue.Show less
