CVE-2020-6463 – chromium-browser: Use after free in ANGLE
https://notcve.org/view.php?id=CVE-2020-6463
Use after free in ANGLE in Google Chrome prior to 81.0.4044.122 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. Un uso de la memoria previamente liberada en ANGLE en Google Chrome versiones anteriores a la versión 81.0.4044.122, permitió a un atacante remoto explotar potencialmente una corrupción de pila por medio de una página HTML diseñada. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00034.html http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2020-08 • CWE-416: Use After Free CWE-787: Out-of-bounds Write •
CVE-2020-9484 – tomcat: deserialization flaw in session persistence storage leading to RCE
https://notcve.org/view.php?id=CVE-2020-9484
When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over; then, using a specifically crafted request, the attacker will be able to trigger remote code execution via deserialization of the file under their control. Note that all of conditions a) to d) must be true for the attack to succeed. Cuando se usa Apache Tomcat versiones 10.0.0-M1 hasta 10.0.0-M4, 9.0.0.M1 hasta 9.0.34, 8.5.0 hasta 8.5.54 y 7.0.0 hasta 7.0. 103, si a) un atacante es capaz de controlar el contenido y el nombre de un archivo en el servidor; y b) el servidor está configurado para usar el PersistenceManager con un FileStore; y c) el PersistenceManager está configurado con sessionAttributeValueClassNameFilter="null" (el valor predeterminado a menos que se utilice un SecurityManager) o un filtro lo suficientemente laxo como para permitir que el objeto proporcionado por el atacante sea deserializado; y d) el atacante conoce la ruta relativa del archivo desde la ubicación de almacenamiento usada por FileStore hasta el archivo sobre el que el atacante presenta control; entonces, mediante una petición específicamente diseñada, el atacante podrá ser capaz de desencadenar una ejecución de código remota mediante la deserialización del archivo bajo su control. Tome en cuenta que todas las condiciones desde la a) hasta la d) deben cumplirse para que el ataque tenga éxito. A deserialization flaw was discovered in Apache Tomcat's use of a FileStore. • https://github.com/masahiro331/CVE-2020-9484 https://github.com/IdealDreamLast/CVE-2020-9484 https://github.com/osamahamad/CVE-2020-9484-Mass-Scan https://github.com/PenTestical/CVE-2020-9484 https://github.com/AssassinUKG/CVE-2020-9484 https://github.com/RepublicR0K/CVE-2020-9484 https://github.com/anjai94/CVE-2020-9484-exploit https://github.com/ColdFusionX/CVE-2020-9484 https://github.com/VICXOR/CVE-2020-9484 https://github.com/seanachao/CVE-2020-9484 https://github& • CWE-502: Deserialization of Untrusted Data •
CVE-2020-10723 – dpdk: librte_vhost Integer truncation in vhost_user_check_and_alloc_queue_pair()
https://notcve.org/view.php?id=CVE-2020-10723
A memory corruption issue was found in DPDK versions 17.05 and above. This flaw is caused by an integer truncation on the index of a payload. Under certain circumstances, the index (a UInt) is copied and truncated into a uint16, which can lead to out of bound indexing and possible memory corruption. Se encontró un problema de corrupción de memoria en DPDK versiones 17.05 y superiores. Este fallo es causado por un truncamiento de enteros en el índice de una carga útil. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00045.html https://bugs.dpdk.org/show_bug.cgi?id=268 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10723 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HRHKFVV4MRWNNJOYQOVP64L4UVWYPEO4 https://usn.ubuntu.com/4362-1 https://www.openwall.com/lists/oss-security/2020/05/18/2 https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security-alerts/cpuoct2020 • CWE-190: Integer Overflow or Wraparound •
CVE-2020-8617 – A logic error in code which checks TSIG validity can be used to trigger an assertion failure in tsig.c
https://notcve.org/view.php?id=CVE-2020-8617
Using a specially-crafted message, an attacker may potentially cause a BIND server to reach an inconsistent state if the attacker knows (or successfully guesses) the name of a TSIG key used by the server. Since BIND, by default, configures a local session key even on servers whose configuration does not otherwise make use of it, almost all current BIND servers are vulnerable. In releases of BIND dating from March 2018 and after, an assertion check in tsig.c detects this inconsistent state and deliberately exits. Prior to the introduction of the check the server would continue operating in an inconsistent state, with potentially harmful results. Al usar un mensaje especialmente diseñado, un atacante puede causar que un servidor BIND alcance un estado inconsistente si el atacante conoce (o adivina con éxito) el nombre de una clave TSIG utilizada por el servidor. • https://www.exploit-db.com/exploits/48521 https://github.com/knqyf263/CVE-2020-8617 http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00044.html http://packetstormsecurity.com/files/157836/BIND-TSIG-Denial-Of-Service.html http://www.openwall.com/lists/oss-security/2020/05/19/4 https://kb.isc.org/docs/cve-2020-8617 https://lists.debian.org/debian-lts-announce/2020/05/msg00031.html https:/ • CWE-617: Reachable Assertion •
CVE-2020-12662 – unbound: amplification of an incoming query into a large number of queries directed to a target
https://notcve.org/view.php?id=CVE-2020-12662
Unbound before 1.10.1 has Insufficient Control of Network Message Volume, aka an "NXNSAttack" issue. This is triggered by random subdomains in the NSDNAME in NS records. Unbound versiones anteriores a 1.10.1, presenta un Control Insuficiente del Volumen de Mensajes de Red, también se conoce como un problema de "NXNSAttack". Esto es activado por subdominios aleatorios en NSDNAME en registros NS. A network amplification vulnerability was found in Unbound, in the way it processes delegation messages from one authoritative zone to another. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00067.html http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00069.html http://www.nxnsattack.com http://www.openwall.com/lists/oss-security/2020/05/19/5 https://lists.debian.org/debian-lts-announce/2021/02/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F5NFROI2OMCZLYRTCNGHGO3TUD32LCIQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/ • CWE-400: Uncontrolled Resource Consumption •
