NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt-python package and not the libvirt-python package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

An injection vulnerability was found in libvirt's virtual network driver. The network XML parser does not strip newline characters from DNS TXT record value attributes and SRV record domain/target attributes. These values are written verbatim into the dnsmasq configuration file generated by the network driver, allowing a user with permission to define virtual networks to inject arbitrary dnsmasq configuration directives such as dhcp-script, leading to arbitrary command execution as root.
