"summary": "libvirt vulnerabilities",
"details": "Vivian Zhang and Christoph Anton Mitterer discovered that libvirt\nincorrectly disabled password authentication when the VNC password was set\nto an empty string. A remote attacker could possibly use this issue to\nbypass authentication, contrary to expectations. This issue only affected\nUbuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-5008)\n\nDaniel P. Berrange discovered that libvirt incorrectly handled validating\nSSL/TLS certificates. A remote attacker could possibly use this issue to\nobtain sensitive information. This issue only affected Ubuntu 17.10.\n(CVE-2017-1000256)\n\nDaniel P. Berrange and Peter Krempa discovered that libvirt incorrectly\nhandled large QEMU replies. An attacker could possibly use this issue to\ncause libvirt to crash, resulting in a denial of service. (CVE-2018-5748)\n\nPedro Sampaio discovered that libvirt incorrectly handled the libnss_dns.so\nmodule. An attacker in a libvirt_lxc session could possibly use this issue\nto execute arbitrary code. This issue only affected Ubuntu 16.04 LTS and\nUbuntu 17.10. (CVE-2018-6764)\n",
