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. (NVD)
