CVSS: 7.5EPSS: 7%CPEs: 15EXPL: 0CVE-2014-7840 – qemu: insufficient parameter validation during ram load
https://notcve.org/view.php?id=CVE-2014-7840
The host_from_stream_offset function in arch_init.c in QEMU, when loading RAM during migration, allows remote attackers to execute arbitrary code via a crafted (1) offset or (2) length value in savevm data. La función host_from_stream_offset en arch_init.c en QEMU, cuando carga RAM durante la migración, permite a atacantes remotos ejecutar código arbitrario a través de un valor (1) offset o (2) length manipulado en datos savevm. It was found that certain values that were read when loading RAM during migration were not validated. A user able to alter the savevm data (either on the disk or over the wire during migration) could use either of these flaws to corrupt QEMU process memory on the (destination) host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=0be839a2701369f669532ea5884c15bead1c6e08 http://rhn.redhat.com/errata/RHSA-2015-0349.html http://rhn.redhat.com/errata/RHSA-2015-0624.html http://thread.gmane.org/gmane.comp.emulators.qemu/306117 https://bugzilla.redhat.com/show_bug.cgi?id=1163075 https://exchange.xforce.ibmcloud.com/vulnerabilities/99194 https://access.redhat.com/security/cve/CVE-2014-7840 • CWE-20: Improper Input Validation CWE-122: Heap-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2014-8564
The _gnutls_ecc_ansi_x963_export function in gnutls_ecc.c in GnuTLS 3.x before 3.1.28, 3.2.x before 3.2.20, and 3.3.x before 3.3.10 allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted (1) Elliptic Curve Cryptography (ECC) certificate or (2) certificate signing requests (CSR), related to generating key IDs. La función _gnutls_ecc_ansi_x963_export en gnutls_ecc.c en GnuTLS 3.x anterior a 3.1.28, 3.2.x anterior a 3.2.20, y 3.3.x anterior a 3.3.10 permite a atacantes remotos causar una denegación de servicio (escritura fuera de rango) a través de un certificado malicioso ECC de tipo (1) curva elíptica criptográfica o (2) peticiones de solicitudes de firma de certificado (CSR), relacionado con la generación de key IDs. An out-of-bounds memory write flaw was found in the way GnuTLS parsed certain ECC (Elliptic Curve Cryptography) certificates or certificate signing requests (CSR). A malicious user could create a specially crafted ECC certificate or a certificate signing request that, when processed by an application compiled against GnuTLS (for example, certtool), could cause that application to crash or execute arbitrary code with the permissions of the user running the application. • http://lists.opensuse.org/opensuse-updates/2014-11/msg00084.html http://rhn.redhat.com/errata/RHSA-2014-1846.html http://secunia.com/advisories/59991 http://secunia.com/advisories/62284 http://secunia.com/advisories/62294 http://www.ubuntu.com/usn/USN-2403-1 https://bugzilla.redhat.com/show_bug.cgi?id=1161443 https://access.redhat.com/security/cve/CVE-2014-8564 • CWE-122: Heap-based Buffer Overflow CWE-310: Cryptographic Issues •

The set_pixel_format function in ui/vnc.c in QEMU allows remote attackers to cause a denial of service (crash) via a small bytes_per_pixel value. La función set_pixel_format en ui/vnc.c en QEMU permite a atacantes remotos causar una denegación de servicio (caída) a través de valores pequeños de bytes_per_pixel. An uninitialized data structure use flaw was found in the way the set_pixel_format() function sanitized the value of bits_per_pixel. An attacker able to access a guest's VNC console could use this flaw to crash the guest. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=e6908bfe8e07f2b452e78e677da1b45b1c0f6829 http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00019.html http://rhn.redhat.com/errata/RHSA-2015-0349.html http://rhn.redhat.com/errata/RHSA-2015-0624.html http://secunia.com/advisories/61484 http://secunia.com/advisories/62143 http://secunia.com/advisories/62144 http://support.citrix.com/article/CTX200892 http://www.debian.org/security/2014/dsa-3066 http://www.debian.org/secu • CWE-20: Improper Input Validation •
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') •

The VGA emulator in QEMU allows local guest users to read host memory by setting the display to a high resolution. El emulador VGA en QEMU permite a usuarios locales invitados leer la memoria del anfitrión mediante la configuración de la pantalla a una resolución alta. An information leak flaw was found in the way QEMU's VGA emulator accessed frame buffer memory for high resolution displays. A privileged guest user could use this flaw to leak memory contents of the host to the guest by setting the display to use a high resolution in the guest. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=ab9509cceabef28071e41bdfa073083859c949a7 http://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=c1b886c45dc70f247300f549dce9833f3fa2def5 http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00014.html http://rhn.redhat.com/errata/RHSA-2014-1669.html http://rhn.redhat.com/errata/RHSA-2014-1670.html http://rhn.redhat.com/errata/RHSA-2014-1941.html http://secunia.com/advisories/61829 http://support.citrix.com/article/CTX200892 http://www.de • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
