CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2018-20856 – kernel: Use-after-free in __blk_drain_queue() function in block/blk-core.c
https://notcve.org/view.php?id=CVE-2018-20856
An issue was discovered in the Linux kernel before 4.18.7. In block/blk-core.c, there is an __blk_drain_queue() use-after-free because a certain error case is mishandled. El servidor web en ZENworks Configuration Management (ZCM) de Novell versión 10.3 y versión 11.2 anteriores a 11.2.4, no realiza apropiadamente la autenticación para el archivo zenworks/jsp/index.jsp, lo que permite a los atacantes remotos realizar ataques de salto de directorio y en consecuencia cargar y ejecutar programas arbitrarios, por medio de una petición al puerto TCP 443. A flaw was found in the Linux kernel’s block driver implementation (blk_drain_queue() function) where a use-after-free condition could be triggered while draining the outstanding command queue in the systems block device subsystem. An attacker could use this flaw to crash the system or corrupt local memory, which may lead to privilege escalation. • http://packetstormsecurity.com/files/154059/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://packetstormsecurity.com/files/154408/Kernel-Live-Patch-Security-Notice-LSN-0055-1.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html https://access.redhat.com/errata/RHSA-2019:3055 https://access.redhat.com/errata/RHSA-2019:3076 https://access.redhat.com/errata/RHSA-2019:3089 https://access.redhat.com/errata/RHSA-2019:3217 https://access&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-416: Use After Free •

CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2019-13648 – kernel: denial of service in arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c via sigreturn() system call
https://notcve.org/view.php?id=CVE-2019-13648
In the Linux kernel through 5.2.1 on the powerpc platform, when hardware transactional memory is disabled, a local user can cause a denial of service (TM Bad Thing exception and system crash) via a sigreturn() system call that sends a crafted signal frame. This affects arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c. En el kernel de Linux hasta versión 5.2.1 sobre la plataforma powerpc, cuando la memoria transaccional de hardware está deshabilitada, un usuario local puede causar una denegación de servicio (excepción de TM Bad Thing y bloqueo del sistema) por medio de una llamada de sistema de la función sigreturn() que envía una trama de señal diseñada. Esto afecta a los archivos arch/powerpc/kernel/signal_32.c y arch/powerpc/kernel/signal_64.c. A flaw was found in the PowerPc platform, where the kernel will panic if the transactional memory is disabled. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00056.html http://packetstormsecurity.com/files/154059/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/07/30/1 https://git.kernel.org/torvalds/c/f16d80b75a096c52354c6e0a574993f3b0dfbdfe https://lists.debian.org/debian-lts-announce/2019/08/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2019-13631
In parse_hid_report_descriptor in drivers/input/tablet/gtco.c in the Linux kernel through 5.2.1, a malicious USB device can send an HID report that triggers an out-of-bounds write during generation of debugging messages. En la función parse_hid_report_descriptor en el archivo drivers/input/tablet/gtco.c en el kernel de Linux hasta versión 5.2.1, un dispositivo USB malicioso puede enviar un informe HID que desencadena una escritura fuera de límites durante la generación de mensajes de depuración. A flaw was found in the Linux kernel's implementation of GTCO tablet/digitizer's version of the parse_hid_report_descriptor in drivers. An attacker with local access could use this flaw to create a specially crafted USB device inserted into the host to corrupt memory, trigger an out-of-bounds write during the generation of debugging messages, or possibly escalate the privileges of a process. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00056.html http://packetstormsecurity.com/files/154059/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.securityfocus.com/bid/109291 https://lists.debian.org/debian-lts-announce/2019/08/msg00016.html https://lists.debian.org/debian-lts-announce/2019/08/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject& • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
