Vulnerability Information

Synopsis

The remote CentOS host is missing one or more security updates.

Description

The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2021:1762 advisory.

- 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)

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

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

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

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

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

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

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.

How to Run

Here is how to run the CentOS 8 : virt:rhel and virt-devel:rhel (CESA-2021:1762) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select CentOS Local Security Checks plugin family.
On the right side table select CentOS 8 : virt:rhel and virt-devel:rhel (CESA-2021:1762) plugin ID 149772.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl centos8_RHSA-2021-1762.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a centos8_RHSA-2021-1762.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - centos8_RHSA-2021-1762.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state centos8_RHSA-2021-1762.nasl -t <IP/HOST>

Go back to menu.
