Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.04 - Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in libvirt.

Software Description: - libvirt: Libvirt virtualization toolkit

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.
