How to Fix CVE-2024-32972

To remediate this vulnerability, upgrade all affected Github.com/ethereum/go ethereum dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/ethereum/go-ethereum fixed: 1.13.15 
Upgrade github.com/ethereum/go-ethereum to 1.13.15
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/ethereum/go-ethereum

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-32972, inspect your project dependencies for Github.com/ethereum/go ethereum:

inspect dependencies for github.com/ethereum/go-ethereum

Analyze the terminal output to locate any version of Github.com/ethereum/go ethereum in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.13.15), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Github.com/ethereum/go ethereum, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact A vulnerable node can be made to consume very large amounts of memory when handling specially crafted p2p messages sent from an attacker node. In order to carry out the attack, the attacker establishes a peer connections to the victim, and sends a malicious `GetBlockHeadersRequest` message with a `count` of `0`, using the `ETH` protocol. In `descendants := chain.GetHeadersFrom(num+count-1, count-1)`, the value of `count-1` is passed to the function `GetHeadersFrom(number, count uint64)` as parameter `count`. Due to integer overflow, `UINT64_MAX` value is then passed as the `count` argument to function `GetHeadersFrom(number, count uint64)`. This allows an attacker to bypass `maxHeadersServe` and request all headers from the latest block back to the genesis block. ### Patches The fix has been included in geth version `1.13.15` and onwards. The vulnerability was patched in: https://github.com/ethereum/go-ethereum/pull/29534 ### Workarounds No workarounds have been made public. ### References No more information is released at this time. ### Credit This issue was disclosed responsibly by DongHan Kim via the Ethereum bug bounty program. Thank you for your cooperation.
