This kernel update is based on upstream -longterm 3.14.27 and fixes the following security issues: 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 (CVE-2014-8133). The paravirt_ops_setup function in arch/x86/kernel/kvm.c in the Linux kernel through 3.18 uses an improper paravirt_enabled setting for KVM guest kernels, which makes it easier for guest OS users to bypass the ASLR protection mechanism via a crafted application that reads a 16-bit value (CVE-2014-8134). The do_double_fault function in arch/x86/kernel/traps.c in the Linux kernel through 3.17.4 does not properly handle faults associated with the Stack Segment (SS) segment register, which allows local users to cause a denial of service (panic) via a modify_ldt system call, as demonstrated by sigreturn_32 in the linux-clock-tests test suite (CVE-2014-9090). arch/x86/kernel/entry_64.S in the Linux kernel before 3.17.5 does not properly handle faults associated with the Stack Segment (SS) segment register, which allows local users to gain privileges by triggering an IRET instruction that leads to access to a GS Base address from the wrong space (CVE-2014-9322). On x86_64 Linux kernels a malicious user program can do a partial ASLR bypass through TLS base addresses leak when attacking other programs (CVE-2014-9419) Linux kernel built with the iso9660 file system (CONFIG_ISO9660_FS) support is vulnerable to an infinite recursion loop flaw, which could lead to a crash or render a system unresponsive/unusable after a while. This occurs while mounting an iso9660 image. An unprivileged user/process could use this flaw to crash the system resulting in DoS (CVE-2014-9420). For other fixes in this update, see the referenced changelogs.
