Ensure mounting of udf filesystems is disabled

낮음레벨 2수동 검토cos

설명

The udf filesystem type is the universal disk format used to implement ISO/IEC 13346 and ECMA-167 specifications. This is an open vendor filesystem type for data storage on a broad range of media. This filesystem type is necessary to support writing DVDs and newer optical disc formats. Removing support for unneeded filesystem types reduces the local attack surface of the system. If this filesystem type is not needed, disable it.
