https://notcve.org/view.php?id=CVE-2018-14653
The Gluster file system through versions 4.1.4 and 3.12 is vulnerable to a heap-based buffer overflow in the '__server_getspec' function via the 'gf_getspec_req' RPC message. A remote authenticated attacker could exploit this to cause a denial of service or other potential unspecified impact. El sistema de archivos Gluster hasta las versiones 3.12 y 4.1.4 es vulnerable a un desbordamiento de búfer basado en memoria dinámica (heap) en la función "__server_getspec" mediante el mensaje RPC "gf_getspec_req". Un atacante remoto autenticado podría explotar esta vulnerabilidad para provocar una denegación de servicio (DoS) u otro impacto sin especificar. A buffer overflow on the heap was found in gf_getspec_req RPC request. • https://access.redhat.com/errata/RHSA-2018:3431 https://access.redhat.com/errata/RHSA-2018:3432 https://access.redhat.com/errata/RHSA-2018:3470 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14653 https://lists.debian.org/debian-lts-announce/2018/11/msg00003.html https://lists.debian.org/debian-lts-announce/2021/11/msg00000.html https://security.gentoo.org/glsa/201904-06 https://access.redhat.com/security/cve/CVE-2018-14653 https://bugzilla.redhat.com/show_bug.cg • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

The Gluster file system through version 4.1.4 is vulnerable to abuse of the 'features/index' translator. A remote attacker with access to mount volumes could exploit this via the 'GF_XATTROP_ENTRY_IN_KEY' xattrop to create arbitrary, empty files on the target server. El sistema de archivos Gluster hasta la versión 4.1.4 es vulnerable al abuso del traductor "features/index". Un atacante remoto con acceso a los volúmenes de montaje podría explotar esta vulnerabilidad mediante el xaatrop "GF_XATTROP_ENTRY_IN_KEY" para crear archivos arbitrarios vacíos en el servidor objetivo.

https://notcve.org/view.php?id=CVE-2018-17958
Qemu has a Buffer Overflow in rtl8139_do_receive in hw/net/rtl8139.c because an incorrect integer data type is used. Qemu tiene un desbordamiento de búfer en rtl8139_do_receive en hw/net/rtl8139.c debido a que se emplea un tipo de datos de enteros incorrecto. An integer overflow issue was found in the RTL8139 NIC emulation in QEMU. It could occur while receiving packets over the network if the size value is greater than INT_MAX. Such overflow would lead to stack buffer overflow issue. • http://www.openwall.com/lists/oss-security/2018/10/08/1 http://www.securityfocus.com/bid/105556 https://access.redhat.com/errata/RHSA-2019:2425 https://access.redhat.com/errata/RHSA-2019:2553 https://lists.debian.org/debian-lts-announce/2019/01/msg00023.html https://lists.gnu.org/archive/html/qemu-devel/2018-09/msg03269.html https://seclists.org/bugtraq/2019/May/76 https://usn.ubuntu.com/3826-1 https://www.debian.org/security/2019/dsa-4454 https://access& • CWE-121: Stack-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2018-17963
qemu_deliver_packet_iov in net/net.c in Qemu accepts packet sizes greater than INT_MAX, which allows attackers to cause a denial of service or possibly have unspecified other impact. qemu_deliver_packet_iov en net/net.c en Qemu acepta tamaños de paquetes mayores a INT_MAX, lo que permite que los atacantes provoquen una denegación de servicio (DoS) o tengan otro tipo de impacto sin especificar. A potential integer overflow issue was found in the networking back-end of QEMU. It could occur while receiving packets, because it accepted packets with large size value. Such overflow could lead to OOB buffer access issue. A user inside guest could use this flaw to crash the QEMU process resulting in DoS. • http://www.openwall.com/lists/oss-security/2018/10/08/1 https://access.redhat.com/errata/RHSA-2019:2166 https://access.redhat.com/errata/RHSA-2019:2425 https://access.redhat.com/errata/RHSA-2019:2553 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2018-09/msg03267.html https://lists.gnu.org/archive/html/qemu-devel/2018-11/msg06054.html https://usn.ubuntu.com/3826-1 https://www.debian.org/securi • CWE-121: Stack-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •
