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 •
