Summary
node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.17, node-tar does not strip NUL bytes from PAX path and linkpath records in src/pax.ts, allowing a crafted archive with values to reach fs.lstat or fs.open and terminate the process with an uncaught exception.
This issue is fixed in version 7.5.17. A remote attacker could craft a malicious archive containing null characters (NUL bytes) in its metadata.
When this archive is processed, the unstripped null characters can cause the application to terminate unexpectedly, leading to a Denial of Service (DoS). Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
Weakness: CWE-170.
Affected products named by the advisory: Confidential Compute Attestation; Cryostat 4; Exploit Intelligence; Migration Toolkit for Containers; and 35 more.
