  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nudf: reject descriptors with oversized CRC length\n\nudf_read_tagged() skips CRC verification when descCRCLength +\nsizeof(struct tag) exceeds the block size.  A crafted UDF image can\nset descCRCLength to an oversized value to bypass CRC validation\nentirely; the descriptor is then accepted based solely on the 8-bit\ntag checksum, which is trivially recomputable.\n\nReject such descriptors instead of silently accepting them.  A\nlegitimate single-block descriptor should never have a CRC length that\nexceeds the block.",
