CVE-2020-13112 – libexif: several buffer over-reads in EXIF MakerNote handling can lead to information disclosure and DoS
https://notcve.org/view.php?id=CVE-2020-13112
An issue was discovered in libexif before 0.6.22. Several buffer over-reads in EXIF MakerNote handling could lead to information disclosure and crashes. This is different from CVE-2020-0093. Se descubrió un problema en libexif versiones anteriores a la versión 0.6.22. Varias lecturas excesivas de buffer en el manejo de EXIF MakerNote podrían conllevar a una divulgación de información y a bloqueos. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00017.html https://github.com/libexif/libexif/commit/435e21f05001fb03f9f186fa7cbc69454afd00d1 https://lists.debian.org/debian-lts-announce/2020/05/msg00025.html https://security.gentoo.org/glsa/202007-05 https://usn.ubuntu.com/4396-1 https://access.redhat.com/security/cve/CVE-2020-13112 https://bugzilla.redhat.com/show_bug.cgi?id=1840344 • CWE-125: Out-of-bounds Read •
CVE-2020-13114 – libexif: unrestricted size in handling Canon EXIF MakerNote data can lead to consumption of large amounts of compute time

An issue was discovered in libexif before 0.6.22. An unrestricted size in handling Canon EXIF MakerNote data could lead to consumption of large amounts of compute time for decoding EXIF data. Se descubrió un problema en el libexif versiones anteriores a la versión 0.6.22. Un tamaño sin restricciones en el manejo de los datos de Canon EXIF MakerNote podría conllevar al consumo de grandes cantidades de tiempo de cálculo para la decodificación de datos EXIF. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00017.html https://github.com/libexif/libexif/commit/e6a38a1a23ba94d139b1fa2cd4519fdcfe3c9bab https://lists.debian.org/debian-lts-announce/2020/05/msg00025.html https://security.gentoo.org/glsa/202007-05 https://usn.ubuntu.com/4396-1 https://access.redhat.com/security/cve/CVE-2020-13114 https://bugzilla.redhat.com/show_bug.cgi?id=1840350 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
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-2020-8617 – 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 •
