-Subject: fs/ntfs: Fix an OOB read when reading data from the resident $DATA
- attribute
-
-When reading a file containing resident data, i.e., the file data is stored in
-the $DATA attribute within the NTFS file record, not in external clusters,
-there are no checks that this resident data actually fits the corresponding
-file record segment.
-
-When parsing a specially-crafted file system image, the current NTFS code will
-read the file data from an arbitrary, attacker-chosen memory offset and of
-arbitrary, attacker-chosen length.
-
-This allows an attacker to display arbitrary chunks of memory, which could
-contain sensitive information like password hashes or even plain-text,
-obfuscated passwords from BS EFI variables.
-
-This fix implements a check to ensure that resident data is read from the
-corresponding file record segment only.
