CVE-2020-29129

ncsi.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length.

Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware platforms. The virt:Rocky Linux module contains packages which provide user-space components used to run virtual machines using KVM. The packages also provide APIs for managing and interacting with the virtualized systems.

Security Fix(es):

• libvirt: double free in qemuAgentGetInterfaces() in qemu_agent.c (CVE-2020-25637)

• QEMU: heap buffer overflow in msix_table_mmio_write() in hw/pci/msix.c (CVE-2020-27821)

• QEMU: ide: atapi: OOB access while processing read commands (CVE-2020-29443)

• QEMU: heap buffer overflow in iscsi_aio_ioctl_cb() in block/iscsi.c may lead to information disclosure (CVE-2020-11947)

• QEMU: reachable assertion failure in net_tx_pkt_add_raw_fragment() in hw/net/net_tx_pkt.c (CVE-2020-16092)

• QEMU: infinite loop in e1000e_write_packet_to_guest() in hw/net/e1000e_core.c (CVE-2020-25707)

• QEMU: assertion failure through usb_packet_unmap() in hw/usb/hcd-ehci.c (CVE-2020-25723)

• QEMU: e1000e: infinite loop scenario in case of null packet descriptor (CVE-2020-28916)

• QEMU: slirp: out-of-bounds access while processing ARP/NCSI packets (CVE-2020-29129, CVE-2020-29130)
