  "details": "In the Linux kernel, the following vulnerability has been resolved:  udf: reject descriptors with oversized CRC length  udf_read_tagged() skips CRC verification when descCRCLength + sizeof(struct tag) exceeds the block size.  A crafted UDF image can set descCRCLength to an oversized value to bypass CRC validation entirely; the descriptor is then accepted based solely on the 8-bit tag checksum, which is trivially recomputable.  Reject such descriptors instead of silently accepting them.  A legitimate single-block descriptor should never have a CRC length that exceeds the block.",
