CVE-2022-23486 (GCVE-0-2022-23486)

Vulnerability from cvelistv5 – Published: 2022-12-07 20:03 – Updated: 2025-04-23 16:31

Title

libp2p-rust denial of service vulnerability from lack of resource management

Summary

libp2p-rust is the official rust language Implementation of the libp2p networking stack. In versions prior to 0.45.1 an attacker node can cause a victim node to allocate a large number of small memory chunks, which can ultimately lead to the victim’s process running out of memory and thus getting killed by its operating system. When executed continuously, this can lead to a denial of service attack, especially relevant on a larger scale when run against more than one node of a libp2p based network. Users are advised to upgrade to `libp2p` `v0.45.1` or above. Users unable to upgrade should reference the DoS Mitigation page for more information on how to incorporate mitigation strategies, monitor their application, and respond to attacks: https://docs.libp2p.io/reference/dos-mitigation/.

GHSA-JVGW-GCCV-Q5P8

Vulnerability from github – Published: 2022-12-07 20:28 – Updated: 2023-07-14 21:53

Summary

libp2p DoS vulnerability from lack of resource management

Details

Impact

An attacker node can cause a victim node to allocate a large number of small memory chunks, which can ultimately lead to the victim’s process running out of memory and thus getting killed by its operating system. When executed continuously, this can lead to a denial of service attack, especially relevant on a larger scale when run against more than one node of a libp2p based network.

Details

In the original version of the attack, the malicious node would continuously open new streams on a single connection using a stream multiplexer that doesn’t provide sufficient back pressure (mplex or yamux). While allocations per stream might be considered small, they multiply with the number of streams and connections. It is easy to defend against this one attack, e.g. by setting a strict per connection stream limit and connection limit. But there are other variations of this attack, e.g. causing memory allocations by sending partial payloads on various protocol levels, forcing the victim to buffer the partial payload for a period of time or by tricking the victim into pre-allocating buffers for messages which are never sent by the attacker.

Patches

Users are advised to upgrade to libp2p v0.45.1 or above.

RUSTSEC-2022-0084 (CVE-2022-23486)

Vulnerability from osv_rustsec – Published: 2022-07-12 12:00 – Updated: 2023-02-02 11:22 – Source website

Summary

libp2p Lack of resource management DoS

Details

libp2p allows a potential attacker to cause victim p2p node to run out of memory

The out of memory failure can cause crashes where libp2p is intended to be used within large scale networks leading to potential Denial of Service (DoS) vector

Users should upgrade or reference the DoS mitigation strategies.

Severity

7.5 (High)
