CVSS: 7.8EPSS: 0%CPEs: 31EXPL: 0CVE-2016-5126 – Qemu: block: iscsi: buffer overflow in iscsi_aio_ioctl
https://notcve.org/view.php?id=CVE-2016-5126
Heap-based buffer overflow in the iscsi_aio_ioctl function in block/iscsi.c in QEMU allows local guest OS users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code via a crafted iSCSI asynchronous I/O ioctl call. Desbordamiento de buffer basado en memoria dinámica en la función iscsi_aio_ioctl en block/iscsi.c en QEMU permite a usuarios locales del SO invitado provocar una denegación de servicio (caída del proceso QEMU) o posiblemente ejecutar código arbitrario a través de una llamada iSCSI ioctl I/O asíncrona manipulada. Quick Emulator(QEMU) built with the Block driver for iSCSI images support (virtio-blk) is vulnerable to a heap-based buffer overflow issue. The flaw could occur while processing iSCSI asynchronous I/O ioctl(2) calls. A user inside a guest could exploit this flaw to crash the QEMU process resulting in denial of service, or potentially leverage it to execute arbitrary code with QEMU-process privileges on the host. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=a6b3167fa0e825aebb5a7cd8b437b6d41584a196 http://rhn.redhat.com/errata/RHSA-2016-1606.html http://rhn.redhat.com/errata/RHSA-2016-1607.html http://rhn.redhat.com/errata/RHSA-2016-1653.html http://rhn.redhat.com/errata/RHSA-2016-1654.html http://rhn.redhat.com/errata/RHSA-2016-1655.html http://rhn.redhat.com/errata/RHSA-2016-1756.html http://rhn.redhat.com/errata/RHSA-2016-1763.html http://www.openwall.com/lists/oss-secu • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
CVSS: 8.8EPSS: 0%CPEs: 47EXPL: 0CVE-2016-3710 – qemu: incorrect banked access bounds checking in vga module
https://notcve.org/view.php?id=CVE-2016-3710
The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue. El módulo VGA en QEMU lleva a cabo incorrectamente comprobaciones de límites sobre acceso almacenado a la memoria de vídeo, lo que permite a administradores locales de SO invitado ejecutar código arbitrario sobre el anfitrión cambiando los modos de acceso después de establecer el banco de registros, también conocido como el problema "Dark Portal". An out-of-bounds read/write access flaw was found in the way QEMU's VGA emulation with VESA BIOS Extensions (VBE) support performed read/write operations using I/O port methods. A privileged guest user could use this flaw to execute arbitrary code on the host with the privileges of the host's QEMU process. • http://rhn.redhat.com/errata/RHSA-2016-0724.html http://rhn.redhat.com/errata/RHSA-2016-0725.html http://rhn.redhat.com/errata/RHSA-2016-0997.html http://rhn.redhat.com/errata/RHSA-2016-0999.html http://rhn.redhat.com/errata/RHSA-2016-1000.html http://rhn.redhat.com/errata/RHSA-2016-1001.html http://rhn.redhat.com/errata/RHSA-2016-1002.html http://rhn.redhat.com/errata/RHSA-2016-1019.html http://rhn.redhat.com/errata/RHSA-2016-1943.html http://suppor • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 5.9EPSS: 96%CPEs: 60EXPL: 2CVE-2016-2107 – OpenSSL - Padding Oracle in AES-NI CBC MAC Check
https://notcve.org/view.php?id=CVE-2016-2107
The AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h does not consider memory allocation during a certain padding check, which allows remote attackers to obtain sensitive cleartext information via a padding-oracle attack against an AES CBC session. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-0169. La implementación de AES-NI en OpenSSL en versiones anteriores a 1.0.1t y 1.0.2 en versiones anteriores a 1.0.2h no considera la asignación de memoria durante una comprobación de relleno determinada, lo que permite a atacantes remotos obtener información de texto claro sensible a través de un ataque de padding-oracle contra una sesión AES CBC . NOTA: esta vulnerabilidad existe debido a una corrección incorrecta para CVE-2013-0169. It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when the connection used the AES CBC cipher suite and the server supported AES-NI. • https://www.exploit-db.com/exploits/39768 https://github.com/FiloSottile/CVE-2016-2107 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.apple.com/archives/security-announce/2016/Jul/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183457.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183607.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/184605.html http://lists.opensuse.org/opensuse-security • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-310: Cryptographic Issues •
