CVSS: 8.1EPSS: 4%CPEs: 60EXPL: 3CVE-2019-6974 – Linux - 'kvm_ioctl_create_device()' NULL Pointer Dereference
https://notcve.org/view.php?id=CVE-2019-6974
In the Linux kernel before 4.20.8, kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandles reference counting because of a race condition, leading to a use-after-free. En el kernel de Linux en versiones anteriores a la 4.20.8, kvm_ioctl_create_device en virt/kvm/kvm_main.c gestiona de manera incorrecta el conteo de referencias debido a una condición de carrera, lo que conduce a un uso de memoria previamente liberada. A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor implements its device control API. While creating a device via kvm_ioctl_create_device(), the device holds a reference to a VM object, later this reference is transferred to the caller's file descriptor table. If such file descriptor was to be closed, reference count to the VM object could become zero, potentially leading to a use-after-free issue. • https://www.exploit-db.com/exploits/46388 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=cfa39381173d5f969daf43582c95ad679189cbc9 http://www.securityfocus.com/bid/107127 https://access.redhat.com/errata/RHBA-2019:0959 https://access.redhat.com/errata/RHSA-2019:0818 https://access.redhat.com/errata/RHSA-2019:0833 https://access.redhat.com/errata/RHSA-2019:2809 https://access.redhat.com/errata/RHSA-2019:3967 https://access.redhat.com/errata/RHSA-2020:0103&# • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVSS: 8.2EPSS: 0%CPEs: 11EXPL: 0CVE-2019-8308 – flatpak: potential /proc based sandbox escape
https://notcve.org/view.php?id=CVE-2019-8308
Flatpak before 1.0.7, and 1.1.x and 1.2.x before 1.2.3, exposes /proc in the apply_extra script sandbox, which allows attackers to modify a host-side executable file. Flatpak, en versiones anteriores a la 1.0.7 y en versiones 1.1.x y 1.2.x anteriores a la 1.2.3, expone /proc en el sandbox de script apply_extra, lo que permite que los atacantes modifiquen un archivo ejecutable del lado del host. A flaw was found in flatpak. In certain special cases, installing flatpak applications and runtimes system-wide may allow an attacker to escape the flatpak sandbox. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00088.html https://access.redhat.com/errata/RHSA-2019:0375 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=922059 https://github.com/flatpak/flatpak/releases/tag/1.0.7 https://github.com/flatpak/flatpak/releases/tag/1.2.3 https://access.redhat.com/security/cve/CVE-2019-8308 https://bugzilla.redhat.com/show_bug.cgi?id=1675070 • CWE-668: Exposure of Resource to Wrong Sphere CWE-672: Operation on a Resource after Expiration or Release •
