CVE-2020-10690 – kernel: use-after-free in cdev_put() when a PTP device is removed while it's chardev is open
https://notcve.org/view.php?id=CVE-2020-10690
There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed, it can cause an exploitable condition as the process wakes up to terminate and clean all attached files. The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the inode. Se presenta un uso de la memoria previamente liberada en kernel versiones anteriores a 5.5, debido a una condición de carrera entre la liberación de ptp_clock y cdev durante la desasignación de recursos. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10690 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://security.netapp.com/advisory/ntap-20200608-0001 https://usn.ubuntu.com/4419-1 https://access.redhat.com/security/cve/CVE-2020-10690 https://bugzilla.redhat.com/show_bug.cgi?id=1817141 • CWE-416: Use After Free •
CVE-2020-10693 – hibernate-validator: Improper input validation in the interpolation of constraint error messages
https://notcve.org/view.php?id=CVE-2020-10693
A flaw was found in Hibernate Validator version 6.1.2.Final. A bug in the message interpolation processor enables invalid EL expressions to be evaluated as if they were valid. This flaw allows attackers to bypass input sanitation (escaping, stripping) controls that developers may have put in place when handling user-controlled data in error messages. Se encontró un fallo en Hibernate Validator versión 6.1.2.Final. Un error en el procesador de interpolación de mensajes permite evaluar expresiones EL no válidas como si fueran válidas. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10693 https://lists.apache.org/thread.html/rb8dca19a4e52b60dab0ab21e2ff9968d78f4b84e4033824db1dd24b4%40%3Cpluto-scm.portals.apache.org%3E https://lists.apache.org/thread.html/rd418deda6f0ebe658c2015f43a14d03acb8b8c2c093c5bf6b880cd7c%40%3Cpluto-dev.portals.apache.org%3E https://lists.apache.org/thread.html/rf9c17c3efc4a376a96e9e2777eee6acf0bec28e2200e4b35da62de4a%40%3Cpluto-dev.portals.apache.org%3E https://www.oracle.com/security-alerts/cpuapr2022.html https://access.redhat.com/security/cve/CVE-202 • CWE-20: Improper Input Validation •

CVE-2020-1722 – ipa: No password length restriction leads to denial of service
https://notcve.org/view.php?id=CVE-2020-1722
A flaw was found in all ipa versions 4.x.x through 4.8.0. When sending a very long password (>= 1,000,000 characters) to the server, the password hashing process could exhaust memory and CPU leading to a denial of service and the website becoming unresponsive. The highest threat from this vulnerability is to system availability. Se encontró un fallo en todas las versiones de ipa 4.x.x hasta 4.8.0. Cuando se envía una contraseña muy larga al servidor (mayores o iguales a 1,000,000 caracteres), el proceso de hashing de contraseña podría agotar la memoria y la CPU, conllevando a una denegación de servicio y el sitio web dejaría de responder. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1722 https://access.redhat.com/security/cve/CVE-2020-1722 https://bugzilla.redhat.com/show_bug.cgi?id=1793071 • CWE-400: Uncontrolled Resource Consumption •
CVE-2020-10696 – buildah: Crafted input tar file may lead to local file overwrite during image build process
https://notcve.org/view.php?id=CVE-2020-10696
A path traversal flaw was found in Buildah in versions before 1.14.5. This flaw allows an attacker to trick a user into building a malicious container image hosted on an HTTP(s) server and then write files to the user's system anywhere that the user has permissions. Se detectó un fallo de salto de ruta en Buildah en versiones anteriores a 1.14.5.
