UBUNTU-CVE-2026-59871
A vulnerability in node-tar prior to version 7.5.18 causes all-digit PAX path and linkpath values to be coerced to JavaScript numbers, leading to a TypeError during path handling. This can result in a denial of service due to application crashes. The issue is fixed in node-tar version 7.5.18.
AI Analysis
Technical Summary
The node-tar library for Node.js versions prior to 7.5.18 improperly coerces all-digit PAX path and linkpath values to JavaScript numbers in src/pax.ts. This causes downstream path handling functions, such as normalizeWindowsPath(entry.path).split('/'), to throw an uncaught TypeError. This behavior can disrupt normal archive processing and cause application crashes. The vulnerability is resolved in version 7.5.18 of node-tar.
Potential Impact
This vulnerability leads to a denial of service condition by causing uncaught TypeErrors during path normalization in affected node-tar versions. There is no indication of confidentiality or integrity impact. No known exploits are reported in the wild.
Mitigation Recommendations
Upgrade node-tar to version 7.5.18 or later, where this issue is fixed. No other mitigation or temporary workaround is indicated.
