Marian Rehak 2020-10-08 11:00:17 UTC Blocks 1886388
Eric Christensen 2020-10-12 17:39:13 UTC Doc Text A flaw was found in the Linux kernel. When using shiftfs with overlayfs and fuse, it is possible to receive the data of files that are supposed to be not readable by the mounter before setting up permissions. It is also possible to copy these files to another mountpoint like a removable device. The highest threat from this vulnerability is to data confidentiality.

Rohit Keshri 2020-12-07 19:56:31 UTC Doc Text A flaw was found in the Linux kernel. When using shiftfs with overlayfs and fuse, it is possible to receive the data of files that are supposed to be not readable by the mounter before setting up permissions. It is also possible to copy these files to another mountpoint like a removable device. The highest threat from this vulnerability is to data confidentiality. A flaw was found in the User namespace on an overlay filesystem in the Linux Kernel, Where a file with no access privilege was able to copy the file to a user defined mount point. An attacker with a special user privilege locally may lead to a kernel information leak problem.
