https://notcve.org/view.php?id=CVE-2018-10879
A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact may occur by renaming a file in a crafted ext4 filesystem image. Se ha detectado una vulnerabilidad en el sistema de archivos ext4 del kernel de Linux. Un usuario local puede provocar un uso de memoria previamente liberada en la función ext4_xattr_set_entry y puede ocurrir una denegación de servicio (DoS) u otro impacto no especificado renombrando una imagen del sistema de archivos ext4 manipulado. • http://patchwork.ozlabs.org/patch/928666 http://patchwork.ozlabs.org/patch/928667 http://www.securityfocus.com/bid/104902 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://bugzilla.kernel.org/show_bug.cgi?id=200001 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10879 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=513f86d73855ce556ea9522b6 • CWE-416: Use After Free •

Linux kernel is vulnerable to a stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could use this to cause a system crash and a denial of service. El kernel de Linux es vulnerable a una escritura de pila fuera de límites en el código del sistema de archivos al montar y escribir en una imagen ext4 manipulada en ext4_update_inline_data().

An integer overflow in the uvesafb_setcmap function in drivers/video/fbdev/uvesafb.c in the Linux kernel before 4.17.4 could result in local attackers being able to crash the kernel or potentially elevate privileges because kmalloc_array is not used. Un desbordamiento de enteros en la función uvesafb_setcmap en drivers/video/fbdev/uvesafb.c en el kernel de Linux en versiones anteriores a la 4.17.4 podría resultar en que los atacantes locales puedan cerrar inesperadamente el kernel o elevar privilegios debido a que no se emplea kmalloc_array. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9f645bcc566a1e9f921bdae7528a01ced5bc3713 http://www.securityfocus.com/bid/104685 http://www.securitytracker.com/id/1041355 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.17.4 https://github.com/torvalds/linux/commit/9f645bcc566a1e9f921bdae7528a01ced5bc3713 https://lists.debian.org/debian-lts-announce/2019/03/msg00017.html https://usn.ubuntu.com/3752-1 https://usn.ubuntu.com/3752-2 https://usn.ubuntu.com& • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2018-13405
The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID. La función inode_init_owner en fs/inode.c en el kernel de Linux hasta la versión 3.16 permite a los usuarios locales crear archivos con una propiedad de grupo no deseada, en un escenario donde un directorio es SGID a un cierto grupo y es escribible por un usuario que no es miembro de ese grupo. • https://www.exploit-db.com/exploits/45033 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0fa3ecd87848c9c93c2c828ef4c3a8ca36ce46c7 http://openwall.com/lists/oss-security/2018/07/13/2 http://www.securityfocus.com/bid/106503 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://access.redhat.com/errata/RHSA-2019:0717 https://access.redhat.com/errata/RHSA- • CWE-269: Improper Privilege Management CWE-284: Improper Access Control •
