  "details" : [ "node-tar is a Tar for Node.js. The node-tar library (<= 7.5.2) fails to sanitize the linkpath of Link (hardlink) and SymbolicLink entries when preservePaths is false (the default secure behavior). This allows malicious archives to bypass the extraction root restriction, leading to Arbitrary File Overwrite via hardlinks and Symlink Poisoning via absolute symlink targets. This vulnerability is fixed in 7.5.3.", "A flaw was found in the node-tar library. This vulnerability allows an attacker to craft malicious archives that, when extracted, can bypass intended security restrictions. This leads to arbitrary file overwrite and symlink poisoning, potentially allowing unauthorized modification of files on the system." ],
  "statement" : "This vulnerability is rated Important for Red Hat products that utilize the node-tar library. The flaw allows an attacker to perform arbitrary file overwrite and symlink poisoning by crafting malicious tar archives. This occurs due to insufficient path sanitization of hardlink and symbolic link entries, even when the default secure behavior (preservePaths is false) is enabled.",
