A vulnerability in node-tar prior to version 7.5.17 allows crafted tar archives containing NUL bytes in PAX path and linkpath records to cause an uncaught exception, terminating the process. This issue is fixed in node-tar version 7.5.17. The vulnerability affects specific Ubuntu package versions of node-tar. It does not impact confidentiality or integrity but can cause denial of service by crashing the process.
AI Analysis
Technical Summary
The node-tar library for Node.js versions prior to 7.5.17 does not properly strip NUL bytes from PAX path and linkpath records in tar archives. This allows a crafted archive to pass values containing NUL bytes to filesystem operations (fs.lstat or fs.open), resulting in an uncaught exception that terminates the process. The vulnerability is resolved in version 7.5.17 of node-tar. The affected versions include specific Ubuntu package releases listed in the input data.
Potential Impact
This vulnerability can cause a denial of service by crashing the Node.js process handling the tar archive. There is no impact on confidentiality or integrity. No known exploits are reported in the wild.
Mitigation Recommendations
Upgrade node-tar to version 7.5.17 or later where this issue is fixed. The affected Ubuntu package versions should be updated to versions including this fix. No other mitigation is indicated.
