Synopsis:          Important: kernel security update
Advisory ID:       SLSA-2017:2795-1
Issue Date:        2017-09-26
CVE Numbers:       CVE-2017-1000253
--

Security Fix(es):

* A flaw was found in the way the Linux kernel loaded ELF executables.
Provided that an application was built as Position Independent Executable
(PIE), the loader could allow part of that application's data segment to
map over the memory area reserved for its stack, potentially resulting in
memory corruption. An unprivileged local user with access to SUID (or
otherwise privileged) PIE binary could use this flaw to escalate their
privileges on the system. (CVE-2017-1000253, Important)
