CVSS: 7.8EPSS: 0%CPEs: 23EXPL: 1CVE-2018-1000199 – kernel: ptrace() incorrect error handling leads to corruption and DoS
https://notcve.org/view.php?id=CVE-2018-1000199
The Linux Kernel version 3.18 contains a dangerous feature vulnerability in modify_user_hw_breakpoint() that can result in crash and possibly memory corruption. This attack appear to be exploitable via local code execution and the ability to use ptrace. This vulnerability appears to have been fixed in git commit f67b15037a7a50c57f72e69a6d59941ad90a0f0f. El kernel de Linux en su versión 3.18 contiene una vulnerabilidad de funcionalidad peligrosa en modify_user_hw_breakpoint() que puede resultar en un cierre inesperado y en una posible corrupción de memoria. El ataque parece ser explotable mediante la ejecución de código local y la capacidad de usar ptrace. • https://github.com/dsfau/CVE-2018-1000199 http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://www.securitytracker.com/id/1040806 https://access.redhat.com/errata/RHSA-2018:1318 https://access.redhat.com/errata/RHSA-2018:1345 https://access.redhat.com/errata/RHSA-2018:1347 https://access.redhat.com/errata/RHSA-2018:1348 https://access.redhat.com/errata/RHSA-2018:1354 https://access.redhat.com/errata/RHSA-2018:1355 https://access.redhat.com/err • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-460: Improper Cleanup on Thrown Exception •
CVSS: 7.8EPSS: 0%CPEs: 29EXPL: 0CVE-2018-10675 – kernel: mm: use-after-free in do_get_mempolicy function allows local DoS or other unspecified impact
https://notcve.org/view.php?id=CVE-2018-10675
The do_get_mempolicy function in mm/mempolicy.c in the Linux kernel before 4.12.9 allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted system calls. La función do_get_mempolicy en mm/mempolicy.c en el kernel de Linux, en versiones anteriores a la 4.12.9, permite que los usuarios locales provoquen una denegación de servicio (uso de memoria previamente liberada) o, posiblemente, causen otros impactos no especificados mediante llamadas del sistema manipuladas. The do_get_mempolicy() function in mm/mempolicy.c in the Linux kernel allows local users to hit a use-after-free bug via crafted system calls and thus cause a denial of service (DoS) or possibly have unspecified other impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=73223e4e2e3867ebf033a5a8eb2e5df0158ccc99 http://www.securityfocus.com/bid/104093 https://access.redhat.com/errata/RHSA-2018:2164 https://access.redhat.com/errata/RHSA-2018:2384 https://access.redhat.com/errata/RHSA-2018:2395 https://access.redhat.com/errata/RHSA-2018:2785 https://access.redhat.com/errata/RHSA-2018:2791 https://access.redhat.com/errata/RHSA-2018:2924 https://access.redhat.com/errata/RHSA-2018& • CWE-416: Use After Free •

CVSS: 5.5EPSS: 0%CPEs: 4EXPL: 0CVE-2018-10535 – binutils: NULL pointer dereference in elf.c
https://notcve.org/view.php?id=CVE-2018-10535
The ignore_section_sym function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, does not validate the output_section pointer in the case of a symtab entry with a "SECTION" type that has a "0" value, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted file, as demonstrated by objcopy. La función ignore_section_sym en elf.c en la biblioteca Binary File Descriptor (BFD), también conocida como libbfd, tal y como se distribuye en GNU Binutils 2.30, no valida el puntero output_section en el caso de que haya una entrada symtab con un tipo "SECTION" que tiene un valor "0". Esto permite que atacantes remotos provoquen una denegación de servicio (desreferencia de puntero NULL y cierre inesperado de la aplicación) mediante un archivo manipulado, tal y como demuestra objcopy. • http://www.securityfocus.com/bid/104021 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3032 https://security.gentoo.org/glsa/201908-01 https://sourceware.org/bugzilla/show_bug.cgi?id=23113 https://usn.ubuntu.com/4336-1 https://access.redhat.com/security/cve/CVE-2018-10535 https://bugzilla.redhat.com/show_bug.cgi?id=1574697 • CWE-476: NULL Pointer Dereference •
CVSS: 5.5EPSS: 0%CPEs: 4EXPL: 0CVE-2018-10534 – binutils: out of bounds memory write in peXXigen.c files
https://notcve.org/view.php?id=CVE-2018-10534
The _bfd_XX_bfd_copy_private_bfd_data_common function in peXXigen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, processes a negative Data Directory size with an unbounded loop that increases the value of (external_IMAGE_DEBUG_DIRECTORY) *edd so that the address exceeds its own memory region, resulting in an out-of-bounds memory write, as demonstrated by objcopy copying private info with _bfd_pex64_bfd_copy_private_bfd_data_common in pex64igen.c. La función _bfd_XX_bfd_copy_private_bfd_data_common en peXXigen.c en la biblioteca Binary File Descriptor (BFD), también conocida como libbfd, tal y como se distribuye en GNU Binutils 2.30, procesa un tamaño Data Directory negativo con un bucle no limitado que aumenta el valor de (external_IMAGE_DEBUG_DIRECTORY) *edd para que la dirección exceda su propia región de memoria, lo que resulta en una escritura en la memoria fuera de límites, tal y como demuestra la copia de información privada por parte de objcopy con _bfd_pex64_bfd_copy_private_bfd_data_common en pex64igen.c. • http://www.securityfocus.com/bid/104025 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3032 https://security.gentoo.org/glsa/201908-01 https://sourceware.org/bugzilla/show_bug.cgi?id=23110 https://usn.ubuntu.com/4336-1 https://access.redhat.com/security/cve/CVE-2018-10534 https://bugzilla.redhat.com/show_bug.cgi?id=1574696 • CWE-787: Out-of-bounds Write •
