CVE-2015-1350 [MEDIUM] Linux kernel (HWE) vulnerabilities
Title: Linux kernel (HWE) vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
USN-3358-1 fixed vulnerabilities in the Linux kernel for Ubuntu 17.04.
This update provides the corresponding updates for the Linux Hardware
Enablement (HWE) kernel from Ubuntu 17.04 for Ubuntu 16.04 LTS. Please
note that this update changes the Linux HWE kernel to the 4.10 based
kernel from Ubuntu 17.04, superseding the 4.8 based HWE kernel from
Ubuntu 16.10.
Ben Harris discovered that the Linux kernel would strip extended privilege
attributes of files when performing a failed unprivileged system call. A
local attacker could use this to cause a denial of service. (CVE-2015-1350)
Ralf Spenneberg discovered that the ext4 implementation in the Linux kernel
did not properly validate
