Summary
libsmb2 through 6.2 Heap Out-of-Bounds Read via File System Info Decoders
Details

libsmb2 through 6.2 contains a heap out-of-bounds read vulnerability in smb2_decode_file_fs_volume_info and smb2_decode_file_fs_attribute_info that allows malicious SMB servers to read past reply buffers. Attackers controlling a server or intercepting unsigned sessions can send crafted QUERY_INFO replies with missing or oversized name lengths to crash the client.
