  ],
  "summary": "Non-exploitable code flaw in libarchive",
  "details": "A flaw was found in libarchive. A NULL pointer is incremented in the ACL parsing logic, specifically within the archive_acl_from_text_nl() function. When processing a malformed ACL string (such as a bare \"d\" or \"default\" tag without subsequent fields), the function fails to perform adequate validation before advancing the pointer. This is not exploitable, since the incremented pointer is not dereferenced.",
