Description :

halfdog discovered that OverlayFS, when mounting on top of a FUSE
mount, incorrectly propagated file attributes, including setuid. A

halfdog discovered that OverlayFS in the Linux kernel incorrectly
propagated security sensitive extended attributes, such as POSIX ACLs.
A local unprivileged attacker could use this to gain privileges.

(FUSE) implementation did not handle initial zero length segments
properly. A local attacker could use this to cause a denial of service
(unkillable task). (CVE-2015-8785).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
