  "title": "libarchive13: A double free issue has been identified in libarchive\u0027s RAR5 reader",
  "description": "A double free issue has been identified in libarchive\u0027s RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.",
