drivers/scsi/libsas/sas_scsi_host.c in the Linux kernel before 4.16 allows local users to cause a denial of service (ata qc leak) by triggering certain failure conditions. NOTE: a third party disputes the relevance of this report because the failure can only occur for physically proximate attackers who unplug SAS Host Bus Adapter cables ** EN DISPUTA ** drivers/scsi/libsas/sas_scsi_host.c en el kernel de Linux en versiones anteriores a la 4.16 permite que los usuarios locales provoquen una denegación de servicio (ata qc leak) al desencadenarse una serie de condiciones de fallo. NOTA: un tercero discute la relevancia de este informe debido a que el error solo puede ocurrir para atacantes físicamente cercanos que desconectan los cables SAS Host Bus Adapter. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=318aaf34f1179b39fa9c30fa0f3288b645beee39 https://bugzilla.suse.com/show_bug.cgi?id=1089281 https://github.com/torvalds/linux/commit/318aaf34f1179b39fa9c30fa0f3288b645beee39 https://lists.debian.org/debian-lts-announce/2018/07/msg00020.html https://usn.ubuntu.com/3678-1 https://usn.ubuntu.com/3678-2 https://usn.ubuntu.com/3678-3 https://usn.ubuntu.com/3678-4 https://usn.ubuntu.com/3696-1 https://usn.ubuntu •

The __get_data_block function in fs/f2fs/data.c in the Linux kernel before 4.11 allows local users to cause a denial of service (integer overflow and loop) via crafted use of the open and fallocate system calls with an FS_IOC_FIEMAP ioctl. La función __get_data_block en fs/f2fs/data.c en el kernel de Linux, en versiones anteriores a la 4.11, permite que usuarios locales provoquen una denegación de servicio (desbordamiento de enteros y bucle) mediante el uso manipulado de las llamadas del sistema open y fallocate con un ioctl FS_IOC_FIEMAP. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b86e33075ed1909d8002745b56ecf73b833db143 https://github.com/torvalds/linux/commit/b86e33075ed1909d8002745b56ecf73b833db143 https://usn.ubuntu.com/3696-1 https://usn.ubuntu.com/3696-2 https://www.debian.org/security/2018/dsa-4188 • CWE-190: Integer Overflow or Wraparound •
CVSS: 7.1EPSS: 0%CPEs: 1EXPL: 1CVE-2018-1095 – kernel: out-of-bound access in fs/posix_acl.c:get_acl() causes crash with crafted ext4 image
https://notcve.org/view.php?id=CVE-2018-1095
The ext4_xattr_check_entries function in fs/ext4/xattr.c in the Linux kernel through 4.15.15 does not properly validate xattr sizes, which causes misinterpretation of a size as an error code, and consequently allows attackers to cause a denial of service (get_acl NULL pointer dereference and system crash) via a crafted ext4 image. La función ext4_xattr_check_entries en fs/ext4/xattr.c en el kernel de Linux hasta la versión 4.15.15 no valida correctamente los tamaños de xattr, lo que provoca una malinterpretación de un tamaño como un código de error y, en consecuencia, permite que los atacantes provoquen una denegación de servicio (desreferencia de puntero NULL en get_acl y cierre inesperado del sistema) mediante una imagen ext4 manipulada. The Linux kernel is vulnerable to an out-of-bound access bug in the fs/posix_acl.c:get_acl() function. An attacker could trick a legitimate user or a privileged attacker could exploit this to cause a system crash or other unspecified impact with a crafted ext4 image. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://openwall.com/lists/oss-security/2018/03/29/1 https://access.redhat.com/errata/RHSA-2018:2948 https://bugzilla.kernel.org/show_bug.cgi?id=199185 https://bugzilla.redhat.com/show_bug.cgi?id=1560793 https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git/commit/?id=ce3fd194fcc6fbdc00ce095a852f22df97baa401 https://usn.ubuntu.com/3695-1 https://usn.ubuntu.com/3695-2 https://access.redhat.com/security/cve/CVE-2018-1095 • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2018-1094
The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.15.15 does not always initialize the crc32c checksum driver, which allows attackers to cause a denial of service (ext4_xattr_inode_hash NULL pointer dereference and system crash) via a crafted ext4 image. La función ext4_fill_super en fs/ext4/super.c en el kernel de Linux hasta la versión 4.15.15 no inicializa siempre el controlador de las sumas de verificación crc32c, lo que permite que los atacantes provoquen una denegación de servicio (desreferencia de puntero NULL en ext4_xattr_inode_hash y cierre inesperado del sistema) mediante una imagen ext4 manipulada. The Linux kernel is vulnerable to a NULL pointer dereference in the ext4/xattr.c:ext4_xattr_inode_hash() function. An attacker could trick a legitimate user or a privileged attacker could exploit this to cause a NULL pointer dereference with a crafted ext4 image. • http://openwall.com/lists/oss-security/2018/03/29/1 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=199183 https://bugzilla.redhat.com/show_bug.cgi?id=1560788 https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git/commit/?id=18db4b4e6fc31eda838dd1c1296d67dbcb3dc957 https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.g • CWE-476: NULL Pointer Dereference •

The ext4_valid_block_bitmap function in fs/ext4/balloc.c in the Linux kernel through 4.15.15 allows attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image because balloc.c and ialloc.c do not validate bitmap block numbers. La función ext4_valid_block_bitmap en fs/ext4/balloc.c en el kernel de Linux hasta la versión 4.15.15 permite que los atacantes provoquen un denegación de servicio (lectura fuera de límites y cierre inesperado del sistema) mediante una imagen ext4 manipulada dado que balloc.c y ialloc.c no validan los números de los bloques de mapa de bits. • http://openwall.com/lists/oss-security/2018/03/29/1 https://bugzilla.kernel.org/show_bug.cgi?id=199181 https://bugzilla.redhat.com/show_bug.cgi?id=1560782 https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git/commit/?id=7dac4a1726a9c64a517d595c40e95e2d0d135f6f https://lists.debian.org/debian-lts-announce/2018/06/msg00000.html https://lists.debian.org/debian-lts-announce/2018/07/msg00015.html https://lists.debian.org/debian-lts-announce/2018/07/msg00016.html https:// • CWE-125: Out-of-bounds Read •
