CVSS: 6.7EPSS: 0%CPEs: 6EXPL: 0CVE-2020-13754 – QEMU: msix: OOB access during mmio operations may lead to DoS
https://notcve.org/view.php?id=CVE-2020-13754
hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address in an msi-x mmio operation. En el archivo hw/pci/msix.c en QEMU versión 4.2.0, permite a usuarios invitados del SO desencadenar un acceso fuera de límites por medio de una dirección diseñada en una operación msi-x mmio. An out-of-bounds access flaw was found in the Message Signalled Interrupt (MSI-X) device support of QEMU. This issue occurs while performing MSI-X mmio operations when a guest sent address goes beyond the mmio region. A guest user or process may use this flaw to crash the QEMU process resulting in a denial of service. • http://www.openwall.com/lists/oss-security/2020/06/01/6 http://www.openwall.com/lists/oss-security/2020/06/15/8 https://lists.debian.org/debian-lts-announce/2020/07/msg00020.html https://lists.gnu.org/archive/html/qemu-devel/2020-06/msg00004.html https://security.gentoo.org/glsa/202011-09 https://security.netapp.com/advisory/ntap-20200608-0007 https://usn.ubuntu.com/4467-1 https://www.debian.org/security/2020/dsa-4728 https://access.redhat.com/security/cve&#x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
