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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
