CVE-2014-9585 – kernel: ASLR bruteforce possible for vdso library
https://notcve.org/view.php?id=CVE-2014-9585
The vdso_addr function in arch/x86/vdso/vma.c in the Linux kernel through 3.18.2 does not properly choose memory locations for the vDSO area, which makes it easier for local users to bypass the ASLR protection mechanism by guessing a location at the end of a PMD. La función vdso_addr en arch/x86/vdso/vma.c en el kernel de Linux hasta 3.18.2 no elige correctamente localizaciones de memoria para la área vDSO, lo que facilita a usuarios locales evadir el mecanismo de protección ASLR mediante la adivinación de una localización al final de un PMD. An information leak flaw was found in the way the Linux kernel's Virtual Dynamic Shared Object (vDSO) implementation performed address randomization. A local, unprivileged user could use this flaw to leak kernel memory addresses to user-space. • http://git.kernel.org/?p=linux/kernel/git/luto/linux.git%3Ba=commit%3Bh=bc3b94c31d65e761ddfe150d02932c65971b74e2 http://git.kernel.org/?p=linux/kernel/git/tip/tip.git%3Ba=commit%3Bh=fbe1bf140671619508dfa575d74a185ae53c5dbb http://lists.fedoraproject.org/pipermail/package-announce/2015-January/148480.html http://lists.opensuse.org/opensuse-security-announce/2015-01/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg0 •
CVE-2014-8134 – kernel: x86: espfix not working for 32-bit KVM paravirt guests
https://notcve.org/view.php?id=CVE-2014-8134
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. La función paravirt_ops_setup en arch/x86/kernel/kvm.c en el kernel de Linux hasta 3.18 utiliza una configuración paravirt_enabled indebida para los kernels KVM invitados, lo que facilita a usuarios invitados del sistema operativo evadir el mecanismo de protección ASLR a través de una aplicación manipulada que lee un valor de 16 bits. It was found that the espfix functionality does not work for 32-bit KVM paravirtualized guests. A local, unprivileged guest user could potentially use this flaw to leak kernel stack addresses. • http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://people.canonical.com/~ubuntu-security/cve/2014/CVE-2014-8134.html http://rhn.redhat.com/errata/RHSA-2016-0855.html http://secunia.com/advisories/62336 http://www.oracle.com/technetwork/t •
CVE-2014-8559 – kernel: fs: deadlock due to incorrect usage of rename_lock
https://notcve.org/view.php?id=CVE-2014-8559
The d_walk function in fs/dcache.c in the Linux kernel through 3.17.2 does not properly maintain the semantics of rename_lock, which allows local users to cause a denial of service (deadlock and system hang) via a crafted application. La función d_walk en fs/dcache.c en el kernel de Linux hasta 3.17.2 no mantiene debidamente la semántica de rename_lock, lo que permite a usuarios locales causar una denegación de servicio (bloqueo y cuelgue del sistema) a través de una aplicación manipulada. A flaw was found in the way the Linux kernel's VFS subsystem handled file system locks. A local, unprivileged user could use this flaw to trigger a deadlock in the kernel, causing a denial of service on the system. • http://lists.opensuse.org/opensuse-security-announce/2015-01/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://rhn.redhat.com/errata/RHSA-2015-1976.html http: • CWE-400: Uncontrolled Resource Consumption •
