13 January 2020
Several security issues were fixed in libvirt.
- libvirt - Libvirt virtualization toolkit
USN-4047-1 fixed a vulnerability in libvirt. This update provides
the corresponding update for Ubuntu 14.04 ESM.
Original advisory details:
Matthias Gerstner and Ján Tomko discovered that libvirt incorrectly handled
certain API calls. An attacker could possibly use this issue to check for
arbitrary files, or execute arbitrary binaries. In the default
installation, attackers would be isolated by the libvirt AppArmor profile.
