ntfsck in NTFS-3G through 2021.8.22 has a heap-based buffer overflow
involving buffer+512*3-2. NOTE: the upstream position is that ntfsck is
deprecated; however, it is shipped by some Linux distributions.
Bugs
Notes
| Author | Note |
|---|---|
| mdeslaur | The ntfsck tool is in the ntfs-3g-dev binary package, which isn’t normally installed, and per upstream “ntfsck does nothing useful, it has been put into the quarantine section, and the distributions should not use it.” Setting priority to low. |
