Summary
Moderate: virt:rhel and virt-devel:rhel security, bug fix, and enhancement update
Details
Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware platforms. The virt:rhel 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)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
