Romance scams cost victims hundreds of millions of dollars a year. As people grow increasingly isolated, and generative AI helps scammers scale their crimes, the problem could get worse.

### Impact Chains using affected versions of Packet Forward Middleware in their IBC Transfer stack are vulnerable to an attack in which there is a potential denial of service. This affects IBC transfers for any asset which is being transferred between another chain and its native chain. We recommend upgrading as soon as possible. __THIS IS A STATE BREAKING CHANGE__ ### Patches Versions [7.2.1](https://github.com/cosmos/ibc-apps/releases/tag/middleware%2Fpacket-forward-middleware%2Fv7.2.1) and [8.1.1](https://github.com/cosmos/ibc-apps/releases/tag/middleware%2Fpacket-forward-middleware%2Fv8.1.1) are patched. ### Workarounds N/A ### References N/A

### Summary Private key can be extracted from ECDSA signature upon signing a malformed input (e.g. a string or a number), which could e.g. come from JSON network input Note that `elliptic` by design accepts hex strings as one of the possible input types ### Details In this code: https://github.com/indutny/elliptic/blob/3e46a48fdd2ef2f89593e5e058d85530578c9761/lib/elliptic/ec/index.js#L100-L107 `msg` is a BN instance after conversion, but `nonce` is an array, and different BN instances could generate equivalent arrays after conversion. Meaning that a same `nonce` could be generated for different messages used in signing process, leading to `k` reuse, leading to private key extraction from a pair of signatures Such a message can be constructed for any already known message/signature pair, meaning that the attack needs only a single malicious message being signed for a full key extraction While signing unverified attacker-controlled messages would be problematic itself (and exploi...

### Summary This report finds 2 availability issues due to the regex used in the `parse-duration` npm package: 1. An event loop delay due to the CPU-bound operation of resolving the provided string, from a 0.5ms and up to ~50ms per one operation, with a varying size from 0.01 MB and up to 4.3 MB respectively. 2. An out of memory that would crash a running Node.js application due to a string size of roughly 10 MB that utilizes unicode characters. ### PoC Refer to the following proof of concept code that provides a test case and makes use of the regular expression in the library as its test case to match against strings: ```js // Vulnerable regex to use from the library: import parse from './index.js' function generateStressTestString(length, decimalProbability) { let result = ""; for (let i = 0; i < length; i++) { if (Math.random() < decimalProbability) { result += "....".repeat(99); } result += Math.floor(Math.random() * 10); } return result; } function ...
