https://notcve.org/view.php?id=CVE-2018-16864
An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when a program with long command line arguments calls syslog. A local attacker may use this flaw to crash systemd-journald or escalate his privileges. Versions through v240 are vulnerable. Se ha descubierto una asignación de memoria sin límites, que podría resultar en que la pila choque con otra región de memoria, en systemd-journald, cuando un programa con argumentos largos de la línea de comandos llama a syslog. Un atacante local podría emplear este error para provocar el cierre inesperado de systemd-journald o escalar sus privilegios. • http://www.openwall.com/lists/oss-security/2021/07/20/2 http://www.securityfocus.com/bid/106523 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2019:0049 https://access.redhat.com/errata/RHSA-2019:0204 https://access.redhat.com/errata/RHSA-2019:0271 https://access.redhat.com/errata/RHSA-2019:0342 https://access.redhat.com/errata/RHSA-2019:0361 https://access.redhat.com/errata/RHSA-2019:2402 https://bugzilla.redhat.com/show_ • CWE-770: Allocation of Resources Without Limits or Throttling •

CVSS: 6.1EPSS: 0%CPEs: 17EXPL: 1CVE-2018-18397 – kernel: userfaultfd bypasses tmpfs file permissions
https://notcve.org/view.php?id=CVE-2018-18397
The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c. La implementación de userfaultfd en el kernel de Linux en versiones anteriores a la 4.17 gestiona de manera incorrecta para ciertas llamadas ioctl UFFDIO_, tal y como queda demostrado al permitir que usuarios locales escriban datos en huecos en un archivo tmpfs (si el usuario tiene acceso de solo lectura a dicho archivo que contiene huecos). Esto está relacionado con fs/userfaultfd.c y mm/userfaultfd.c. A flaw was found in the Linux kernel with files on tmpfs and hugetlbfs. An attacker is able to bypass file permissions on filesystems mounted with tmpfs/hugetlbs to modify a file and possibly disrupt normal system behavior. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=29ec90660d68bbdd69507c1c8b4e33aa299278b1 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2019:0163 https://access.redhat.com/errata/RHSA-2019:0202 https://access.redhat.com/errata/RHSA-2019:0324 https://access.redhat.com/errata/RHSA-2019:0831 https://bugs.chromium.org/p/project-zero/issues/detail?id=1700 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.14.87& • CWE-20: Improper Input Validation CWE-863: Incorrect Authorization •
