branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Fixes CVE-2018-10906 - In fuse before versions 2.9.8 and 3.x before 3.2.5,
fusermount is vulnerable to a restriction bypass when SELinux is active.
This allows non-root users to mount a FUSE file system with the
'allow_other' mount option regardless of whether 'user_allow_other' is set
in the fuse configuration. An attacker may use this flaw to mount a FUSE
file system, accessible by other users, and trick them into accessing files
on that file system, possibly causing Denial of Service or other unspecified
effects.
And additionally:
- libfuse no longer segfaults when fuse_interrupted() is called outside the
event loop.
- The fusermount binary has been hardened in several ways to reduce
potential attack surface. Most importantly, mountpoints and mount options
must now match a hard-coded whitelist. It is expected that this whitelist
covers all regular use-cases.
