CVE-2017-1000407 – Kernel: KVM: DoS via write flood to I/O port 0x80
https://notcve.org/view.php?id=CVE-2017-1000407
The Linux Kernel 2.6.32 and later are affected by a denial of service, by flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic. El kernel de Linux en versiones 2.6.32 y posteriores se ha visto afectado por una denegación de servicio (DoS): al inundar el puerto de diagnóstico 0x80 puede ocurrir una excepción que conduce a una situación de pánico del kernel. Linux kernel Virtualization Module (CONFIG_KVM) for the Intel processor family (CONFIG_KVM_INTEL) is vulnerable to a DoS issue. It could occur if a guest was to flood the I/O port 0x80 with write requests. A guest user could use this flaw to crash the host kernel resulting in DoS. • http://www.openwall.com/lists/oss-security/2017/12/04/2 http://www.securityfocus.com/bid/102038 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2019:1170 https://access.redhat.com/security/cve/cve-2017-1000407 https://lists.debian.org/debian-lts-announce/2017/12/msg00004.html https://usn.ubuntu.com/3583-1 https://usn.ubuntu.com/3583-2 https://usn.ubuntu.com/3617-1 https • CWE-248: Uncaught Exception CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVE-2018-5344 – kernel: drivers/block/loop.c mishandles lo_release serialization allowing denial-of-service
https://notcve.org/view.php?id=CVE-2018-5344
In the Linux kernel through 4.14.13, drivers/block/loop.c mishandles lo_release serialization, which allows attackers to cause a denial of service (__lock_acquire use-after-free) or possibly have unspecified other impact. En el kernel de Linux hasta la versión 4.14.13, drivers/block/loop.c gestiona de manera incorrecta la serialización de lo_release, lo que permite que atacantes provoquen una denegación de servicio (uso de memoria previamente liberada de __lock_acquire) o, posiblemente, otro impacto sin especificar. A flaw was found in the Linux kernel's handling of loopback devices. An attacker, who has permissions to setup loopback disks, may create a denial of service or other unspecified actions. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ae6650163c66a7eff1acd6eb8b0f752dcfa8eba5 http://www.securityfocus.com/bid/102503 https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://github.com/torvalds/linux/commit/ae6650163c66a7eff1acd6eb8b0f752dcfa8eba5 https://usn.ubuntu.com/3583-1 https://usn.ubuntu.com/3583-2 https://usn.ubuntu.com/3617-1 https://usn.ubuntu • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVE-2016-9573 – openjpeg: heap out-of-bounds read due to insufficient check in imagetopnm()
https://notcve.org/view.php?id=CVE-2016-9573
An out-of-bounds read vulnerability was found in OpenJPEG 2.1.2, in the j2k_to_image tool. Converting a specially crafted JPEG2000 file to another format could cause the application to crash or, potentially, disclose some data from the heap. Se ha detectado una vulnerabilidad de lectura fuera de límites en OpenJPEG 2.1.2, en la herramienta j2k_to_image. La conversión de un archivo JPEG2000 especialmente manipulado a otro formato podría provocar que la aplicación se cierre inesperadamente o, potencialmente, revele algunos datos de la memoria dinámica (heap).
