Description

Boxo, formerly known as go-libipfs, is a library for building IPFS applications and implementations. In versions 0.4.0 and 0.5.0, if an attacker is able allocate arbitrary many bytes in the Bitswap server, those allocations are lasting even if the connection is closed. This affects users accepting untrusted connections with the Bitswap server and also affects users using the old API stubs at `github.com/ipfs/go-libipfs/bitswap` because users then transitively import `github.com/ipfs/go-libipfs/bitswap/server`. Boxo versions 0.6.0 and 0.4.1 contain a patch for this issue. As a workaround, those who are using the stub object at `github.com/ipfs/go-libipfs/bitswap` not taking advantage of the features provided by the server can refactor their code to use the new split API that will allow them to run in a client only mode: `github.com/ipfs/go-libipfs/bitswap/client`.

Severity

 

CVSS Version 3.x CVSS Version 2.0

CVSS 3.x Severity and Metrics:

NIST: NVD

Base Score:  7.5 HIGH

Vector:  CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CNA:  GitHub, Inc.

Base Score:  8.2 HIGH

Vector:  CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H

NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.

CVSS 2.0 Severity and Metrics:

NIST: NVD

Base Score: N/A
