Scientific Linux Security Update : libvirt on SL7.x x86_64

Medium Nessus Plugin ID 95846


The remote Scientific Linux host is missing one or more security updates.


The following packages have been upgraded to a newer upstream version:
libvirt (2.0.0).

Security Fix(es) :

- It was found that the libvirt daemon, when using RBD (RADOS Block Device), leaked private credentials to the process list. A local attacker could use this flaw to perform certain privileged operations within the cluster. (CVE-2015-5160)

- A path-traversal flaw was found in the way the libvirt daemon handled filesystem names for storage volumes. A libvirt user with privileges to create storage volumes and without privileges to create and modify domains could possibly use this flaw to escalate their privileges. (CVE-2015-5313)

- It was found that setting a VNC password to an empty string in libvirt did not disable all access to the VNC server as documented, instead it allowed access with no authentication required. An attacker could use this flaw to access a VNC server with an empty VNC password without any authentication. (CVE-2016-5008)


Update the affected packages.
