GHSA-v6rw-hhgg-wc4x: Evmos vulnerable to DOS and transaction fee expropiation through Authz exploit

## Impact _What kind of vulnerability is it? Who is impacted?_ An attacker can use this bug to bypass the block gas limit and gas payment completely to perform a full Denial-of-Service against the chain. ## Disclosure Evmos versions below `v11.0.1` do not check for `MsgEthereumTx` messages that are nested under other messages. This allows a malicious actor to perform EVM transactions that do not meet the checks performed under `newEthAnteHandler`. This opens the possibility for the DOS of validators and consequently halt the chain through an infinite EVM execution. ### Additional details The attack scenario is as follows: 1. The attacker deploys a simple smart contract with an infinite loop to the chain. 2. The attacker calls the smart contract using an embedded transaction with an extremely high gas value (`uint64` max or similar). 3. Once the transaction is included in a block, nodes will try to execute the EVM transaction with almost infinite gas and get stuck. **This stops...

GHSA-46c8-635v-68r2: Keycloak Authorization Bypass vulnerability

Due to a permissive regular expression hardcoded for filtering allowed hosts to register a dynamic client, a malicious user with enough information about the environment could benefit and jeopardize an environment with this specific Dynamic Client Registration with TrustedDomain configuration previously unauthorized. #### Acknowledgements: Special thanks to Bastian Kanbach for reporting this issue and helping us improve our security.

GHSA-mrv8-pqfj-7gp5: Keycloak path traversal vulnerability in the redirect validation

An issue was found in the redirect_uri validation logic that allows for a bypass of otherwise explicitly allowed hosts.

pgAdmin 8.3 Remote Code Execution

pgAdmin versions 8.3 and below have a path traversal vulnerability within their session management logic that can allow a pickled file to be loaded from an arbitrary location. This can be used to load a malicious, serialized Python object to execute code within the context of the target application. This exploit supports two techniques by which the payload can be loaded, depending on whether or not credentials are specified. If valid credentials are provided, Metasploit will login to pgAdmin and upload a payload object using pgAdmin's file management plugin. Once uploaded, this payload is executed via the path traversal before being deleted using the file management plugin. This technique works for both Linux and Windows targets. If no credentials are provided, Metasploit will start an SMB server and attempt to trigger loading the payload via a UNC path. This technique only works for Windows targets. For Windows 10 v1709 (Redstone 3) and later, it also requires that insecure outbound g...

Debian Linux Security Advisory 5662-1 - Multiple vulnerabilities have been discovered in the Apache HTTP server, which may result in HTTP response splitting or denial of service.

Ubuntu Security Notice USN-6726-3

Ubuntu Security Notice 6726-3 - Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a guest VM could possibly use this to cause a denial of service. It was discovered that the IPv6 implementation of the Linux kernel did not properly manage route cache memory usage. A remote attacker could use this to cause a denial of service.
