Description Vasyl Kaigorodov 2014-12-19 16:01:14 UTC

the following vulnerability:

Name: CVE-2014-8135

Assigned: 20141010
Reference: http://secunia.com/advisories/61111

The storageVolUpload function in storage/storage_driver.c in libvirt
does not check a certain return value, which allows local users to
cause a denial of service (NULL pointer dereference and daemon crash)
via a crafted offset value in a "virsh vol-upload" command.
