CVSS: 7.0EPSS: 0%CPEs: 55EXPL: 1CVE-2019-6454 – systemd: Insufficient input validation in bus_process_object() resulting in PID 1 crash
https://notcve.org/view.php?id=CVE-2019-6454
An issue was discovered in sd-bus in systemd 239. bus_process_object() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic). Se ha descubierto un problema en sd-bus en systemd 239. bus_process_object() en libsystemd/sd-bus/bus-objects.c asigna un búfer de pila de longitud variable para almacenar temporalmente la ruta de objeto de los mensajes D-Bus entrantes. Un usuario local sin privilegios puede explotar esto enviando un mensaje especialmente manipulado a PID1, provocando que el puntero de la pila salte por las páginas guard de la pila hasta una región de memoria no mapeada y desencadene una denegación de servicio (cierre inesperado del PID1 en systemd y pánico del kernel). It was discovered that systemd allocates a buffer large enough to store the path field of a dbus message without performing enough checks. • http://lists.opensuse.org/opensuse-security-announce/2019-02/msg00070.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00062.html http://www.openwall.com/lists/oss-security/2019/02/18/3 http://www.openwall.com/lists/oss-security/2019/02/19/1 http://www.openwall.com/lists/oss-security/2021/07/20/2 http://www.securityfocus.com/bid/107081 https://access.redhat.com/errata/RHSA-2019:0368 https://access.redhat.com/errata/RHSA-2019:0990 https://access • CWE-20: Improper Input Validation CWE-787: Out-of-bounds Write •
CVSS: 8.1EPSS: 3%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 •
