CVE-2015-1328

Priority
High
Description
The overlayfs implementation in the linux (aka Linux kernel) package before
3.19.0-21.21 in Ubuntu through 15.04 does not properly check permissions
for file creation in the upper filesystem directory, which allows local
users to obtain root access by leveraging a configuration in which
overlayfs is permitted in an arbitrary mount namespace.
Ubuntu-Description
Philip Pettersson discovered a privilege escalation when using overlayfs
mounts inside of user namespaces. A local user could exploit this flaw to
gain administrative privileges on the system.
