  "summary": "Updated parted package fixes security vulnerabilities",
  "details": "A heap-based buffer overflow can occur when processing a specially\ncrafted FAT32 filesystem due to an integer calculation error during\nbuffer allocation. A local attacker could exploit this by enticing a\nuser or automated service to open a malicious filesystem image,\nresulting in an application crash leading to a Denial of Service (DoS)\nor potential memory corruption.\nA heap-based buffer overflow exists in libparted's file system resizing\nlogic when handling FAT16 volumes. By convincing a user or administrator\nto resize a specially crafted FAT16 file system image with malformed\ndirectory metadata, an attacker can trigger an oversized read into a\nfixed-size memory buffer. This issue causes memory corruption, resulting\nin an application crash and a denial of service (DoS).\n",
