CVE-2019-14835 – kernel: vhost-net: guest to host kernel escape during migration
https://notcve.org/view.php?id=CVE-2019-14835
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host. Se encontró un fallo de desbordamiento de búfer, en las versiones desde 2.6.34 hasta 5.2.x, en la manera en que la funcionalidad vhost del kernel de Linux que traduce los búferes virtueue en IOV, registraba los descriptores del búfer durante una migración. Un usuario invitado privilegiado capaz de pasar descriptores con una longitud no válida hacia el host cuando la migración está en marcha, podría usar este fallo para aumentar sus privilegios sobre el host. A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://packetstormsecurity.com/files/154572/Kernel-Live-Patch-Security-Notice-LSN-0056-1.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200115-01- • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2019-10086 – apache-commons-beanutils: does not suppresses the class property in PropertyUtilsBean by default
https://notcve.org/view.php?id=CVE-2019-10086
In Apache Commons Beanutils 1.9.2, a special BeanIntrospector class was added which allows suppressing the ability for an attacker to access the classloader via the class property available on all Java objects. We, however were not using this by default characteristic of the PropertyUtilsBean. En Apache Commons Beanutils 1.9.2, se agregó una clase especial BeanIntrospector que permite suprimir la capacidad de un atacante para acceder al cargador de clases a través de la propiedad de clase disponible en todos los objetos Java. Sin embargo, no se esta usando esta característica por defecto de PropertyUtilsBean. A flaw was found in the Apache Commons BeanUtils, where the class property in PropertyUtilsBean is not suppressed by default. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00007.html http://mail-archives.apache.org/mod_mbox/www-announce/201908.mbox/%3cC628798F-315D-4428-8CB1-4ED1ECC958E4%40apache.org%3e https://access.redhat.com/errata/RHSA-2019:4317 https://access.redhat.com/errata/RHSA-2020:0057 https://access.redhat.com/errata/RHSA-2020:0194 https://access.redhat.com/errata/RHSA-2020:0804 https://access.redhat.com/errata/RHSA-2020:0805 https://access.redhat.com/errata/RHSA-2020:0806 • CWE-502: Deserialization of Untrusted Data •
CVE-2019-11775 – JDK: Failure to privatize a value pulled out of the loop by versioning
https://notcve.org/view.php?id=CVE-2019-11775
All builds of Eclipse OpenJ9 prior to 0.15 contain a bug where the loop versioner may fail to privatize a value that is pulled out of the loop by versioning - for example if there is a condition that is moved out of the loop that reads a field we may not privatize the value of that field in the modified copy of the loop allowing the test to see one value of the field and subsequently the loop to see a modified field value without retesting the condition moved out of the loop. This can lead to a variety of different issues but read out of array bounds is one major consequence of these problems. Todas las compilaciones de OpenJ9 de Eclipse anteriores a versión 0.15, contienen un bug donde el versionador de bucle puede fallar al privatizar un valor que se extrae del bucle mediante el versionado – por ejemplo, si hay una condición que es movida fuera del bucle que lee un campo no podemos privatizar el valor de ese campo en la copia modificada del bucle permitiendo a la prueba visualizar un valor del campo y posteriormente el bucle para visualizar un valor del campo modificado sin volver a probar la condición movida fuera del bucle. Esto puede conllevar a una variedad de problemas diferentes, pero la lectura fuera de límites de la matriz es una consecuencia importante de estos problemas. • https://access.redhat.com/errata/RHSA-2019:2494 https://access.redhat.com/errata/RHSA-2019:2495 https://access.redhat.com/errata/RHSA-2019:2585 https://access.redhat.com/errata/RHSA-2019:2590 https://access.redhat.com/errata/RHSA-2019:2592 https://access.redhat.com/errata/RHSA-2019:2737 https://bugs.eclipse.org/bugs/show_bug.cgi?id=549601 https://access.redhat.com/security/cve/CVE-2019-11775 https://bugzilla.redhat.com/show_bug.cgi?id=1738549 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
CVE-2019-2816 – OpenJDK: Missing URL format validation (Networking, 8221518)
https://notcve.org/view.php?id=CVE-2019-2816
Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: Networking). Supported versions that are affected are Java SE: 7u221, 8u212, 11.0.3 and 12.0.1; Java SE Embedded: 8u211. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE, Java SE Embedded accessible data as well as unauthorized read access to a subset of Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00044.html http://www.oracle.com/technetwork/security-advisory/cpujul2019-5072835.html https://access.redhat.com/errata/RHSA-2019:2494 https://access.redhat.com/errata/RHSA-2019:2495 https://access.redhat.com/errata/RHSA-2019:2585 https://access.redhat.com/errata/RHSA-2019:2590 https://access.redhat.com/errata/RHSA-2019:2592 https://access.redhat.com • CWE-20: Improper Input Validation •
