CVE-2018-18710
https://notcve.org/view.php?id=CVE-2018-18710
An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658. Se ha descubierto un problema en el kernel de Linux hasta la versión 4.19. Una fuga de información en cdrom_ioctl_select_disc en drivers/cdrom/cdrom.c podría ser empleada por atacantes locales para leer memoria del kernel debido a que una conversión de un long no firmado a int interfiere con la comprobación de límites. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e4f3aa2e1e67bb48dfbaaf1cad59013d5a5bc276 http://www.securityfocus.com/bid/106041 https://github.com/torvalds/linux/commit/e4f3aa2e1e67bb48dfbaaf1cad59013d5a5bc276 https://lists.debian.org/debian-lts-announce/2019/03/msg00017.html https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html https://lists.debian.org/debian-lts-announce/2019/04/msg00004.html https://usn.ubuntu.com/3846-1 https://usn.ubuntu.com/3847-1 ht • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2018-18690 – kernel: filesystem corruption due to an unchecked error condition during an xfs attribute change
https://notcve.org/view.php?id=CVE-2018-18690
In the Linux kernel before 4.17, a local attacker able to set attributes on an xfs filesystem could make this filesystem non-operational until the next mount by triggering an unchecked error condition during an xfs attribute change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c mishandles ATTR_REPLACE operations with conversion of an attr from short to long form. En el kernel de Linux en versiones anteriores a la 4.17, un atacante local que sea capaz de establecer atributos en un sistema de archivos xfs podría hacer que este sistema de archivos no esté operativo hasta el siguiente montaje desencadenando una condición de error no marcada. Esto se debe a que xfs_attr_shortform_addname en fs/xfs/libxfs/xfs_attr.c gestiona de manera incorrecta las operaciones ATTR_REPLACE con la conversión de un attr de forma corta a forma larga. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7b38460dc8e4eafba06c78f8e37099d3b34d473c http://www.securityfocus.com/bid/105753 https://bugzilla.kernel.org/show_bug.cgi?id=199119 https://bugzilla.suse.com/show_bug.cgi?id=1105025 https://github.com/torvalds/linux/commit/7b38460dc8e4eafba06c78f8e37099d3b34d473c https://lists.debian.org/debian-lts-announce/2019/03/msg00017.html https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html https://lists.debian.org/debian- • CWE-391: Unchecked Error Condition CWE-754: Improper Check for Unusual or Exceptional Conditions •

CVE-2018-12389 – Mozilla: Memory safety bugs fixed in Firefox ESR 60.3
https://notcve.org/view.php?id=CVE-2018-12389
Mozilla developers and community members reported memory safety bugs present in Firefox ESR 60.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox ESR < 60.3 and Thunderbird < 60.3. Los desarrolladores de Mozilla y los miembros de la comunidad reportaron problemas de seguridad existentes en Firefox ESR 60.2. Algunos de estos errores mostraban evidencias de corrupción de memoria y se cree que, con el esfuerzo necesario, se podrían explotar para ejecutar código arbitrario. • http://www.securityfocus.com/bid/105723 http://www.securityfocus.com/bid/105769 http://www.securitytracker.com/id/1041944 https://access.redhat.com/errata/RHSA-2018:3005 https://access.redhat.com/errata/RHSA-2018:3006 https://access.redhat.com/errata/RHSA-2018:3531 https://access.redhat.com/errata/RHSA-2018:3532 https://bugzilla.mozilla.org/buglist.cgi?bug_id=1498460%2C1499198 https://lists.debian.org/debian-lts-announce/2018/11/msg00008.html https://lists.debian.org/debian • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
