The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.
xsa224 xen: grant table operations mishandle reference counts (XSA-224) (CVE-2017-10921)
The qemu implementation in libvirt before 1.3.0 and Xen allows local guest OS users to cause a denial of service (host disk consumption) by writing to stdout or stderr. (CVE-2014-3672)
Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUS_STARTPACKET set and then a crafted packet with TXSTATUS_DEVICEOWNS set. (CVE-2015-3209)
Note that Nessus has not tested for these issues but has instead relied on the package manager’s report that the package is installed.
