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: 8.4EPSS: 0%CPEs: 35EXPL: 0CVE-2016-2857 – Qemu: net: out of bounds read in net_checksum_calculate()
https://notcve.org/view.php?id=CVE-2016-2857
The net_checksum_calculate function in net/checksum.c in QEMU allows local guest OS users to cause a denial of service (out-of-bounds heap read and crash) via the payload length in a crafted packet. La función net_checksum_calculate en net/checksum.c en QEMU permite a usuarios del SO invitado provocar una denegación de servicio (lectura de memoria dinámica fuera de rango y caída) a través de una longitud de la carga útil en un paquete manipulado. An out-of-bounds read-access flaw was found in the QEMU emulator built with IP checksum routines. The flaw could occur when computing a TCP/UDP packet's checksum, because a QEMU function used the packet's payload length without checking against the data buffer's size. A user inside a guest could use this flaw to crash the QEMU process (denial of service). • http://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=362786f14a753d8a5256ef97d7c10ed576d6572b http://rhn.redhat.com/errata/RHSA-2016-2670.html http://rhn.redhat.com/errata/RHSA-2016-2671.html http://rhn.redhat.com/errata/RHSA-2016-2704.html http://rhn.redhat.com/errata/RHSA-2016-2705.html http://rhn.redhat.com/errata/RHSA-2016-2706.html http://rhn.redhat.com/errata/RHSA-2017-0083.html http://rhn.redhat.com/errata/RHSA-2017-0309.html http://rhn.redhat.com/errata/RHSA- • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

It was found that redhat-support-plugin-rhev passed a user-specified path and file name directly to the command line in the log viewer component. This could allow users with the SuperUser role on any Entity to execute arbitrary commands on any host in the RHEV environment. • https://bugzilla.redhat.com/show_bug.cgi?id=1269588 https://rhn.redhat.com/errata/RHSA-2016-0426.html https://access.redhat.com/security/cve/CVE-2015-7544 • CWE-20: Improper Input Validation CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

https://notcve.org/view.php?id=CVE-2014-3561
The rhevm-log-collector package in Red Hat Enterprise Virtualization 3.4 uses the PostgreSQL database password on the command line when calling sosreport, which allows local users to obtain sensitive information by listing the processes. El paquete rhevm-log-collector en Red Hat Enterprise Virtualization 3.4 utiliza la contraseña de la base de datos PostgreSQL en la línea de comandos cuando llama a sosreport, lo que permite a usuarios locales obtener información sensible mediante el listado de los procesos. It was found that rhevm-log-collector called sosreport with the PostgreSQL database password passed as a command line parameter. A local attacker could read this password by monitoring a process listing. The password would also be written to a log file, which could potentially be read by a local attacker. • http://rhn.redhat.com/errata/RHSA-2014-1947.html http://www.securitytracker.com/id/1031291 https://exchange.xforce.ibmcloud.com/vulnerabilities/99096 https://access.redhat.com/security/cve/CVE-2014-3561 https://bugzilla.redhat.com/show_bug.cgi?id=1122781 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-522: Insufficiently Protected Credentials •

https://notcve.org/view.php?id=CVE-2014-7169
GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271. GNU Bash hasta 4.3 bash43-025 procesa cadenas finales después de la definición malformada de funciones en los valores de variables de entorno, lo que permite a atacantes remotos escribir hacia ficheros o posiblemente tener otro impacto desconocido a través de un entorno manipulado, tal y como se ha demostrado por vectores que involucran la característica ForceCommand en sshd OpenSSH, los módulos mod_cgi y mod_cgid en el Apache HTTP Server, scripts ejecutados por clientes DHCP no especificados, y otras situaciones en la cual establecer el entorno ocurre a través de un límite privilegiado de la ejecución de Bash. Nota: Esta vulnerabilidad existe debido a una solución incompleta para CVE-2014-6271. It was found that the fix for CVE-2014-6271 was incomplete, and Bash still allowed certain characters to be injected into other environments via specially crafted environment variables. • https://www.exploit-db.com/exploits/34777 https://www.exploit-db.com/exploits/34895 https://www.exploit-db.com/exploits/34839 https://www.exploit-db.com/exploits/36503 https://www.exploit-db.com/exploits/36504 https://www.exploit-db.com/exploits/34766 https://www.exploit-db.com/exploits/35115 https://www.exploit-db.com/exploits/36933 https://www.exploit-db.com/exploits/34765 https://www.exploit-db.com/exploits/34860 https://www.exploit-db.com/exploits/34879 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-228: Improper Handling of Syntactically Invalid Structure •
