In the Linux Kernel before version 4.15.8, 4.14.25, 4.9.87, 4.4.121, 4.1.51, and 3.2.102, an error in the "_sctp_make_chunk()" function (net/sctp/sm_make_chunk.c) when handling SCTP packets length can be exploited to cause a kernel crash. En el kernel de Linux en versiones anteriores a la 4.15.8, 4.14.25, 4.9.87, 4.4.121, 4.1.51 y 3.2.102, un error en la función "_sctp_make_chunk()" (net/sctp/sm_make_chunk.c) al gestionar el tamaño de paquetes SCTP puede explotarse para provocar un cierre inesperado del kernel. An error in the "_sctp_make_chunk()" function (net/sctp/sm_make_chunk.c) when handling SCTP, packet length can be exploited by a malicious local user to cause a kernel crash and a DoS. • https://access.redhat.com/errata/RHSA-2018:1854 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-2019:0641 https://cdn.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.2.102 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.1.51 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.14.25 https://cdn.kernel.org/p • CWE-20: Improper Input Validation •
CVSS: 8.8EPSS: 0%CPEs: 18EXPL: 0CVE-2018-7550 – QEMU: i386: multiboot OOB access while loading kernel image
https://notcve.org/view.php?id=CVE-2018-7550
The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access. La función load_multiboot en hw/i386/multiboot.c en Quick Emulator (también conocido como QEMU) permite que usuarios locales invitados del sistema operativo ejecuten código arbitrario en el host QEMU mediante un valor mh_load_end_addr mayor que mh_bss_end_addr. Esto desencadena un acceso de lectura o escritura a la memoria fuera de límites. Quick Emulator (QEMU), compiled with the PC System Emulator with multiboot feature support, is vulnerable to an OOB r/w memory access issue. The issue could occur while loading a kernel image during the guest boot, if mh_load_end_addr address is greater than the mh_bss_end_addr address. • http://www.securityfocus.com/bid/103181 https://access.redhat.com/errata/RHSA-2018:1369 https://access.redhat.com/errata/RHSA-2018:2462 https://bugzilla.redhat.com/show_bug.cgi?id=1549798 https://github.com/orangecertcc/security-research/security/advisories/GHSA-f49v-45qp-cv53 https://lists.debian.org/debian-lts-announce/2018/04/msg00015.html https://lists.debian.org/debian-lts-announce/2018/04/msg00016.html https://lists.debian.org/debian-lts-announce/2018/09/msg00007.html https:&#x • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (integer underflow or overflow, and application crash) via an ELF file with a corrupt DWARF FORM block, as demonstrated by nm. dwarf2.c en la biblioteca Binary File Descriptor (BFD), conocida como libbfd, tal y como se distribuye en GNU Binutils 2.30, permite que atacantes remotos provoquen una denegación de servicio (desbordamiento o subdesbordamiento de enteros y cierre inesperado de la aplicación) mediante un archivo ELF con un bloque DWARF FORM corrupto, tal y como demuestra nm. An integer wraparound has been discovered in the Binary File Descriptor (BFD) library distributed in GNU Binutils up to version 2.30.
