https://notcve.org/view.php?id=CVE-2014-3647
arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel through 3.17.2 does not properly perform RIP changes, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application. arch/x86/kvm/emulate.c en el subsistema KVM en el kernel de Linux hasta 3.17.2 no realiza debidamente los cambios RIP, lo que permite a usuarios del sistema operativo invitado causar una denegación de servicio (caída del sistema operativo invitado) a través de una aplicación manipulada. A flaw was found in the way the Linux kernel's KVM subsystem handled non-canonical addresses when emulating instructions that change the RIP (for example, branches or calls). A guest user with access to an I/O or MMIO region could use this flaw to crash the guest. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=234f3ce485d54017f15cf5e0699cff4100121601 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=d1442d85cc30ea75f7d399474ca738e0bc96f715 http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://www.debian.org/security/2014/dsa-3060 http://www.openwall.com/lists/oss-security/2014/10/24/9 http:/ • CWE-248: Uncaught Exception •

https://notcve.org/view.php?id=CVE-2014-3646
arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel through 3.17.2 does not have an exit handler for the INVVPID instruction, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application. arch/x86/kvm/vmx.c en el subsistema KVM en el kernel de Linux hasta 3.17.2 no tiene un manejador de salida para la instrucción INVVPID, lo que permite a usuarios del sistema operativo invitado causar una denegación de servicio (caída del sistema operativo invitado) a través de una aplicación manipulada. It was found that the Linux kernel's KVM subsystem did not handle the VM exits gracefully for the invvpid (Invalidate Translations Based on VPID) instructions. On hosts with an Intel processor and invppid VM exit support, an unprivileged guest user could use these instructions to crash the guest. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a642fc305053cc1c6e47e4f4df327895747ab485 http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://rhn.redhat.com/errata/RHSA-2015-0126.html http://rhn.redhat.com/errata/RHSA-2015-0284.html http://www.debian.org/security/2014/dsa-3060 http://www.openwall.com/lists/oss-security/2014/10/24/9 http://www. • CWE-248: Uncaught Exception •
CVSS: 5.0EPSS: 97%CPEs: 147EXPL: 1CVE-2014-3566 – SSL/TLS: Padding Oracle On Downgraded Legacy Encryption attack
https://notcve.org/view.php?id=CVE-2014-3566
The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue. El protocolo SSL 3.0, utilizado en OpenSSL hasta 1.0.1i y otros productos, utiliza relleno (padding) CBC no determinístico, lo que facilita a los atacantes man-in-the-middle obtener datos de texto plano a través de un ataque de relleno (padding) oracle, también conocido como el problema "POODLE". A flaw was found in the way SSL 3.0 handled padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining (CBC) mode. This flaw allows a man-in-the-middle (MITM) attacker to decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a victim application to repeatedly send the same data over newly created SSL 3.0 connections. • https://github.com/mikesplain/CVE-2014-3566-poodle-cookbook ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2014-015.txt.asc http://advisories.mageia.org/MGASA-2014-0416.html http://aix.software.ibm.com/aix/efixes/security/openssl_advisory11.asc http://archives.neohapsis.com/archives/bugtraq/2014-10/0101.html http://archives.neohapsis.com/archives/bugtraq/2014-10/0103.html http://askubuntu.com/questions/537196/how-do-i-patch-workaround-sslv3-poodle-vulnerability-cve-2014-3566 http& • CWE-310: Cryptographic Issues CWE-757: Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade') •

https://notcve.org/view.php?id=CVE-2014-8086
Race condition in the ext4_file_write_iter function in fs/ext4/file.c in the Linux kernel through 3.17 allows local users to cause a denial of service (file unavailability) via a combination of a write action and an F_SETFL fcntl operation for the O_DIRECT flag. Condición de carrera en la función ext4_file_write_iter en fs/ext4/file.c en el kernel de Linux hasta 3.17 permite a usuarios locales causar una denegación de servicio (no disponibilidad de ficheros) a través de una combinación de una acción de escritura y una operación F_SETFL fcntl para el indicador O_DIRECT. A race condition flaw was found in the Linux kernel's ext4 file system implementation that allowed a local, unprivileged user to crash the system by simultaneously writing to a file and toggling the O_DIRECT flag using fcntl(F_SETFL) on that file. • http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00004.html http://rhn.redhat.com/errata/RHSA-2015-0290.html http://rhn.redhat.com/errata/RHSA-2015-0694.html http://www.openwall.com/lists/oss-security/2014/10/09/25 http://www.securityfocus.com/bid/70376 http://www.spinics.net/lists/linux-ext4/msg45683.html http://www.spinics.net/lists/linux-ext4/msg45685.html https://bugzilla.redhat.com/show_bug.cgi?id=1151353 https://exchange.xforce.ibmcloud.com/vulnerabi • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

The pivot_root implementation in fs/namespace.c in the Linux kernel through 3.17 does not properly interact with certain locations of a chroot directory, which allows local users to cause a denial of service (mount-tree loop) via .
