Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:4676 advisory.

 - QEMU: Slirp: use-after-free during packet reassembly (CVE-2019-15890)

 - libvirt: Potential DoS by holding a monitor job while querying QEMU guest-agent (CVE-2019-20485)

 - libvirt: Potential denial of service via active pool without target path (CVE-2020-10703)

 - libvirt: leak of sensitive cookie information via dumpxml (CVE-2020-14301)

 - libvirt: leak of /dev/mapper/control into QEMU guests (CVE-2020-14339)

 - QEMU: slirp: use-after-free in ip_reass() function in ip_input.c (CVE-2020-1983)
