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 •

net/netfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces. net/netfilter/xt_osf.c en el kernel de Linux hasta la versión 4.14.4 no requiere la capacidad CAP_NET_ADMIN para operaciones "add_callback" y "remove_callback", lo que permite que usuarios locales omitan las restricciones de acceso establecidas debido a que la estructura de datos xt_osf_fingers se comparte entre todos los espacios de nombres de la red. • http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00007.html http://www.securityfocus.com/bid/102110 https://lkml.org/lkml/2017/12/5/982 https://usn.ubuntu.com/3583-1 https://usn.ubuntu.com/3583-2 https://usn.ubuntu.com/3617-1 https://usn.ubuntu.com/3617-2 https://usn.ubuntu.com/3617-3 https://usn.ubuntu.com/3619-1 https://usn.ubuntu.com/3619-2 https://usn.ubuntu.com/3632-1 https://www.debian.org/security/2017/dsa-4073 • CWE-862: Missing Authorization •
