In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
ntfs: do not mark the volume clean in sync_fs when errors were recorded<\/p>\n
ntfs_put_super() and the remount-read-only path both clear the dirty bit
\nonly when NVolErrors(vol) is false. ntfs_sync_fs() clears it
\nunconditionally, so any sync() on a volume that recorded an error marks
\nthat volume clean. A volume without this set is then seen as not needing
\nrecovery and it does not run one, so whatever went wrong is never repaired.<\/p>\n
This change skips resetting the dirty bit when there are volume errors.<\/p>\n
Reproduced on a volume whose $MFTMirr does not match $MFT, which sets the
\nerror flag while leaving the mount read-write: after a write and a sync,
\nthe on-disk volume flags read 0x0000 with this driver and 0x0001 with the
\nguard in place.<\/p>\n","protected":false},"excerpt":{"rendered":"
