Omission of the .desktop filetype from the Safe Browsing checklist in SafeBrowsing in Google Chrome on Linux prior to 72.0.3626.81 allowed an attacker who convinced a user to download a .desktop file to execute arbitrary code via a downloaded .desktop file. La omisión del tipo de archivo ".desktop" de la lista de control en SafeBrowsing en Google Chrome en Linux, en versiones anteriores a la 72.0.3626.81, permitía a un atacante, que convenció a un usuario para que descargara un archivo ".desktop", ejecutar código arbitrario mediante un archivo ".desktop" descargado. • http://www.securityfocus.com/bid/106767 https://access.redhat.com/errata/RHSA-2019:0309 https://chromereleases.googleblog.com/2019/01/stable-channel-update-for-desktop.html https://crbug.com/904182 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JVFHYCJGMZQUKYSIE2BXE4NLEGFGUXU5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZQOP53LXXPRGD4N5OBKGQTSMFXT32LF6 https://www.debian.org/security/2019/dsa-4395 https://access.redhat.com&# • CWE-862: Missing Authorization •
CVSS: 5.5EPSS: 0%CPEs: 2EXPL: 0CVE-2018-16885 – kernel: out-of-bound read in memcpy_fromiovecend()
https://notcve.org/view.php?id=CVE-2018-16885
A flaw was found in the Linux kernel that allows the userspace to call memcpy_fromiovecend() and similar functions with a zero offset and buffer length which causes the read beyond the buffer boundaries, in certain cases causing a memory access fault and a system halt by accessing invalid memory address. This issue only affects kernel version 3.10.x as shipped with Red Hat Enterprise Linux 7. Se ha detectado un fallo en el kernel de Linux que permite al espacio de usuario llamar a memcpy_fromiovecend() y funciones similares con un offset de 0 y un tamaño de búfer que causa la lectura fuera de los límites de dicho búfer. En algunos casos, esto provoca un fallo de acceso a la memoria y la detención del sistema, accediendo a direcciones de memoria inválidas. Este problema solo afecta a las versiones 3.10.x del kernel, incluidas por defecto en Red Hat Enterprise Linux 7. • http://www.securityfocus.com/bid/106296 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16885 https://access.redhat.com/security/cve/CVE-2018-16885 https://bugzilla.redhat.com/show_bug.cgi?id=1661503 • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2018-16884
A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. Se ha encontrado un error en el subsistema de archivos NFS41+ del kernel de Linux. • http://www.securityfocus.com/bid/106253 https://access.redhat.com/errata/RHSA-2019:1873 https://access.redhat.com/errata/RHSA-2019:1891 https://access.redhat.com/errata/RHSA-2019:2696 https://access.redhat.com/errata/RHSA-2019:2730 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://access.redhat.com/errata/RHSA-2020:0204 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16884 https://lists.debian.org/debian-lts • CWE-416: Use After Free •
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 •
