CVE-2018-10881 – kernel: out-of-bound access in ext4_get_group_info() when mounting and operating a crafted ext4 image
https://notcve.org/view.php?id=CVE-2018-10881
A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on 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 acceso fuera de límites en la función ext4_get_group_info, una denegación de servicio (DoS) y un cierre inesperado del sistema montando y operando una imagen del sistema de archivos ext4 especialmente manipulada. • http://patchwork.ozlabs.org/patch/929792 http://www.securityfocus.com/bid/104901 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=200015 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10881 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6e8ab72a812396996035a37e5ca4b3b99b5d214b https://lists.debian.org/debia • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
CVE-2018-10901 – kernel: kvm: vmx: host GDT limit corruption
https://notcve.org/view.php?id=CVE-2018-10901
A flaw was found in Linux kernel's KVM virtualization subsystem. The VMX code does not restore the GDT.LIMIT to the previous host value, but instead sets it to 64KB. With a corrupted GDT limit a host's userspace code has an ability to place malicious entries in the GDT, particularly to the per-cpu variables. An attacker can use this to escalate their privileges. Se encontró un fallo en el subsistema de virtualización KVM del kernel de Linux. • http://www.securityfocus.com/bid/104905 https://access.redhat.com/errata/RHSA-2018:2390 https://access.redhat.com/errata/RHSA-2018:2391 https://access.redhat.com/errata/RHSA-2018:2392 https://access.redhat.com/errata/RHSA-2018:2393 https://access.redhat.com/errata/RHSA-2018:2394 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10901 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3444d7da1839b851eefedd372978d8a982316c36 https://help.ecostruxureit. • CWE-665: Improper Initialization •
CVE-2018-1336 – tomcat: A bug in the UTF-8 decoder can lead to DoS
https://notcve.org/view.php?id=CVE-2018-1336
An improper handing of overflow in the UTF-8 decoder with supplementary characters can lead to an infinite loop in the decoder causing a Denial of Service. Versions Affected: Apache Tomcat 9.0.0.M9 to 9.0.7, 8.5.0 to 8.5.30, 8.0.0.RC1 to 8.0.51, and 7.0.28 to 7.0.86. Una gestión incorrecta del desbordamiento en el decodificador UTF-8 con caracteres suplementarios puede conducir a un bucle infinito en el decodificador, provocando una denegación de servicio (DoS). Versiones afectadas: Apache Tomcat de la versión 9.0.0.M9 a la 9.0.7, de la 8.5.0 a la 8.5.30, de la 8.0.0.RC1 a la 8.0.51 y de la versión 7.0.28 a la 7.0.86. • http://mail-archives.us.apache.org/mod_mbox/www-announce/201807.mbox/%3C20180722090435.GA60759%40minotaur.apache.org%3E http://www.securityfocus.com/bid/104898 http://www.securitytracker.com/id/1041375 https://access.redhat.com/errata/RHEA-2018:2188 https://access.redhat.com/errata/RHEA-2018:2189 https://access.redhat.com/errata/RHSA-2018:2700 https://access.redhat.com/errata/RHSA-2018:2701 https://access.redhat.com/errata/RHSA-2018:2740 https://access.redhat.com/errata/RHSA-20 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2018-10906 – fusermount - user_allow_other Restriction Bypass and SELinux Label Control
https://notcve.org/view.php?id=CVE-2018-10906
In fuse before versions 2.9.8 and 3.x before 3.2.5, fusermount is vulnerable to a restriction bypass when SELinux is active. This allows non-root users to mount a FUSE file system with the 'allow_other' mount option regardless of whether 'user_allow_other' is set in the fuse configuration. An attacker may use this flaw to mount a FUSE file system, accessible by other users, and trick them into accessing files on that file system, possibly causing Denial of Service or other unspecified effects. En fuse, en versiones anteriores a la 2.9.8 y en versiones 3.x anteriores a la 3.2.5, fusermount es vulnerable a una omisión de restricciones cuando SELinux está activo. Esto permite que usuarios no root monten un sistema de archivos FUSE con la opción "allow_other", independientemente de si "user_allow_other" está establecido en la configuración de fuse. • https://www.exploit-db.com/exploits/45106 https://access.redhat.com/errata/RHSA-2018:3324 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10906 https://lists.debian.org/debian-lts-announce/2018/08/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5XYA6PXT5PPWVK7CM7K4YRCYWA37DODB https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/A253TZWZK6R7PT2S5JIEAQJR2TYKX7V2 https://lists.fedoraproject.org/archives/list/package • CWE-269: Improper Privilege Management CWE-285: Improper Authorization •
CVE-2018-13988 – poppler: out of bounds read in pdfunite
https://notcve.org/view.php?id=CVE-2018-13988
Poppler through 0.62 contains an out of bounds read vulnerability due to an incorrect memory access that is not mapped in its memory space, as demonstrated by pdfunite. This can result in memory corruption and denial of service. This may be exploitable when a victim opens a specially crafted PDF file. Poppler hasta la versión 0.62 contiene una vulnerabilidad de lectura fuera de límites debido a un acceso incorrecto a la memoria que no se mapea en su espacio de memoria, tal y como queda demostrado con pdfunite.
