https://notcve.org/view.php?id=CVE-2018-13785
In libpng 1.6.34, a wrong calculation of row_factor in the png_check_chunk_length function (pngrutil.c) may trigger an integer overflow and resultant divide-by-zero while processing a crafted PNG file, leading to a denial of service. En libpng 1.6.34, un cálculo erróneo de row_factor en la función png_check_chunk_length (pngrutil.c) podría desencadenar un desbordamiento de enteros y una división entre cero resultante al procesar un archivo PNG manipulado, lo que conduciría a una denegación de servicio (DoS). • http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/105599 http://www.securitytracker.com/id/1041889 https://access.redhat.com/errata/RHSA-2018:3000 https://access.redhat.com/errata/RHSA-2018:3001 https://access.redhat.com/errata/RHSA-2018:3002 https://access.redhat.com/errata/RHSA-2018:3003 https://access.redhat.com/errata/RHSA-2018:3007 https://access.redhat.com/errata/RHSA-2018:3008 https://access.redhat.com/errata/ • CWE-190: Integer Overflow or Wraparound CWE-369: Divide By Zero •
CVSS: 7.8EPSS: 0%CPEs: 92EXPL: 1CVE-2018-13405 – Linux (Ubuntu) - Other Users coredumps Can Be Read via setgid Directory and killpriv Bypass
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 •

https://notcve.org/view.php?id=CVE-2018-12910
The get_cookies function in soup-cookie-jar.c in libsoup 2.63.2 allows attackers to have unspecified impact via an empty hostname. La función get_cookies en soup-cookie-jar.c en libsoup 2.63.2 permite que los atacantes provoquen un impacto no especificado mediante un nombre de host vacío. An out-of-bounds read has been discovered in libsoup when getting cookies from a URI with empty hostname. An attacker may use this flaw to cause a crash in the application. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00003.html https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3140 https://access.redhat.com/errata/RHSA-2018:3505 https://gitlab.gnome.org/GNOME/gnome-sdk-images/commit/4215b8a21b3b3055e947312a8920df94f93ba047 https://gitlab.gnome.org/GNOME/libsoup/commit/db2b0d5809d5f8226d47312b40992cadbcde439f https://gitlab.gnome.org/GNOME/libsoup/issues/3 https://lists.debian.org/debian-lts-announce/2018/07/msg00007. • CWE-125: Out-of-bounds Read •

setup before version 2.11.4-1.fc28 in Fedora and Red Hat Enterprise Linux added /sbin/nologin and /usr/sbin/nologin to /etc/shells. This violates security assumptions made by pam_shells and some daemons which allow access based on a user's shell being listed in /etc/shells. Under some circumstances, users which had their shell changed to /sbin/nologin could still access the system. setup en versiones anteriores a la 2.11.4-1.fc28 en Fedora y Red Hat Enterprise Linux añadía /sbin/nologin y /usr/sbin/nologin a /etc/shells. Esto viola las asunciones de seguridad realizadas por pam_shells y algunos demonios, lo que permite el acceso en base a que el shell de un usuario se lista en /etc/shells.

https://notcve.org/view.php?id=CVE-2018-13033
The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (excessive memory allocation and application crash) via a crafted ELF file, as demonstrated by _bfd_elf_parse_attributes in elf-attrs.c and bfd_malloc in libbfd.c. This can occur during execution of nm. La biblioteca Binary File Descriptor (BFD), conocida como libbfd, tal y como se distribuye en GNU Binutils 2.30 y anteriores permite que atacantes remotos provoquen una denegación de servicio (asignación excesiva de memoria y cierre inesperado de la aplicación) mediante un archivo ELF manipulado. Esto queda demostrado por _bfd_elf_parse_attributes en elf-attrs.c y bfd_malloc en libbfd.c.
