https://notcve.org/view.php?id=CVE-2018-17962
Qemu has a Buffer Overflow in pcnet_receive in hw/net/pcnet.c because an incorrect integer data type is used. Qemu tiene un desbordamiento de búfer en pcnet_receive en hw/net/pcnet.c debido a que se emplea un tipo de datos de enteros incorrecto. An integer overflow issue was found in the AMD PC-Net II NIC emulation in QEMU. It could occur while receiving packets, if the size value was greater than INT_MAX. Such overflow would lead to stack buffer overflow issue. • http://www.openwall.com/lists/oss-security/2018/10/08/1 https://access.redhat.com/errata/RHSA-2019:2892 https://access.redhat.com/security/cve/cve-2018-17962 https://linux.oracle.com/cve/CVE-2018-17962.html https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2018-09/msg03268.html https://usn.ubuntu.com/3826-1 https://www.debian.org/security/2018/dsa-4338 https://www.suse.com/security/cve/CVE-2 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •

An uncontrolled resource consumption flaw has been discovered in redhat-certification in the way documents are loaded. A remote attacker may provide an existing but invalid XML file which would be opened and never closed, possibly producing a Denial of Service. Se ha descubierto un fallo de consumo no controlado de recursos en redhat-certification en la forma en la que se cargan los documentos. Un atacante remoto puede proporcionar un archivo XML existente pero no válido que se abriría y nunca se cerraría, produciendo posiblemente una denegación de servicio. • https://access.redhat.com/errata/RHSA-2018:2373 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10864 https://access.redhat.com/security/cve/CVE-2018-10864 https://bugzilla.redhat.com/show_bug.cgi?id=1593627 • CWE-400: Uncontrolled Resource Consumption •

A vulnerability was found in the way RemoteMessageChannel, introduced in jboss-remoting versions 3.3.10, reads from an empty buffer. An attacker could use this flaw to cause denial of service via high CPU caused by an infinite loop. Se ha encontrado una vulnerabilidad en la forma en la que RemoteMessageChannel, introducido en las versiones 3.3.10 de jboss-remoting, lee desde un búfer vacío. Un atacante podría emplear este error para provocar una denegación de servicio (DoS) mediante un consumo alto de CPU a través de un bucle infinito.

CVSS: 7.8EPSS: 0%CPEs: 6EXPL: 0CVE-2016-7039 – kernel: remotely triggerable unbounded recursion in the vlan gro code leading to a kernel crash
https://notcve.org/view.php?id=CVE-2016-7039
The IP stack in the Linux kernel through 4.8.2 allows remote attackers to cause a denial of service (stack consumption and panic) or possibly have unspecified other impact by triggering use of the GRO path for large crafted packets, as demonstrated by packets that contain only VLAN headers, a related issue to CVE-2016-8666. La pila IP en el kernel de Linux hasta la versión 4.8.2 permite a atacantes remotos provocar una denegación de servicio (consumo de pila y pánico) o tener otro posible impacto no especificado desencadenando uso de la ruta GRO para paquetes grandes manipulados, como se demuestra por los paquetes que contienen solo cabeceras VLAN, un problema relacionado con CVE-2016-8666. Linux kernel built with the 802.1Q/802.1ad VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local Area Network(CONFIG_VXLAN) with Transparent Ethernet Bridging(TEB) GRO support, is vulnerable to a stack overflow issue. It could occur while receiving large packets via GRO path, as an unlimited recursion could unfold in both VLAN and TEB modules, leading to a stack corruption in the kernel. • http://rhn.redhat.com/errata/RHSA-2016-2047.html http://rhn.redhat.com/errata/RHSA-2016-2107.html http://rhn.redhat.com/errata/RHSA-2016-2110.html http://www.openwall.com/lists/oss-security/2016/10/10/15 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.oracle.com/technetwork/topics/security/ovmbulletinoct2016-3090547.html http://www.securityfocus.com/bid/93476 https://access.redhat.com/errata/RHSA-2017:0372 https://bto.bluecoat.com/ • CWE-399: Resource Management Errors CWE-674: Uncontrolled Recursion •
CVSS: 7.8EPSS: 0%CPEs: 23EXPL: 4CVE-2016-5425 – Apache Tomcat on RedHat Based Systems Insecure Temp Config Privilege Escalation
https://notcve.org/view.php?id=CVE-2016-5425
The Tomcat package on Red Hat Enterprise Linux (RHEL) 7, Fedora, CentOS, Oracle Linux, and possibly other Linux distributions uses weak permissions for /usr/lib/tmpfiles.d/tomcat.conf, which allows local users to gain root privileges by leveraging membership in the tomcat group. El paquete Tomcat en Red Hat Enterprise Linux (RHEL) 7, Fedora, CentOS, Oracle Linux y posiblemente en otros productos distribuidos por Linux utiliza permisos débiles para /usr/lib/tmpfiles.d/tomcat.conf, lo que permite a usuarios locales obtener privilegios de root aprovechando su pertenencia al grupo tomcat. It was discovered that the Tomcat packages installed configuration file /usr/lib/tmpfiles.d/tomcat.conf writeable to the tomcat group. A member of the group or a malicious web application deployed on Tomcat could use this flaw to escalate their privileges. Apache Tomcat versions 8, 7, and 6 suffer from a privilege escalation vulnerability on RedHat-based distros. • https://www.exploit-db.com/exploits/40488 http://legalhackers.com/advisories/Tomcat-RedHat-Pkgs-Root-PrivEsc-Exploit-CVE-2016-5425.html http://packetstormsecurity.com/files/139041/Apache-Tomcat-8-7-6-Privilege-Escalation.html http://rhn.redhat.com/errata/RHSA-2016-2046.html http://www.openwall.com/lists/oss-security/2016/10/10/2 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.securityfocus.com/bid/93472 http://www.securitytracker.com/id/1036979&# • CWE-276: Incorrect Default Permissions CWE-284: Improper Access Control •
