Malware in pre-build binaries

Critical
justmoon published GHSA-7cgc-fjv4-52x6 May 24, 2023

Package

npm bignum (npm)

Affected versions

>=0.12.2

Patched versions

0.13.1

Description

Impact

bignum releases from v0.12.2 to v0.13.0 (inclusive) used node-pre-gyp to optionally download pre-built binary versions of the addon. These binaries were published on a now-expired S3 bucket which has since been claimed by a malicious third party which is now serving binaries containing malware that exfiltrates data from the user's computer.

Patches

v0.13.1 does not use node-pre-gyp and does not have support for downloading pre-built binaries in any form, avoiding the risk of malicious downloads.

Critical
