CVE-2014-8133 (retired)

Priority
Description
arch/x86/kernel/tls.c in the Thread Local Storage (TLS) implementation in
the Linux kernel through 3.18.1 allows local users to bypass the espfix
protection mechanism, and consequently makes it easier for local users to
bypass the ASLR protection mechanism, via a crafted application that makes
a set_thread_area system call and later reads a 16-bit value.
Ubuntu-Description
Andy Lutomirski discovered an information leak in the Linux kernel's Thread
Local Storage (TLS) implementation allowing users to bypass the espfix to
obtain information that could be used to bypass the Address Space Layout
Randomization (ASLR) protection mechanism. A local user could exploit this
flaw to obtain potentially sensitive information from kernel memory.
