Debian DSA-3181-1 : xen - security update

high Nessus Plugin ID 81748


The remote Debian host is missing a security-related update.


Multiple security issues have been found in the Xen virtualisation solution :

- CVE-2015-2044 Information leak via x86 system device emulation.

- CVE-2015-2045 Information leak in the HYPERVISOR_xen_version() hypercall.

- CVE-2015-2151 Missing input sanitising in the x86 emulator could result in information disclosure, denial of service or potentially privilege escalation.

In addition the Xen developers reported an unfixable limitation in the handling of non-standard PCI devices. Please refer to for further information.


Upgrade the xen packages.

For the stable distribution (wheezy), these problems have been fixed in version 4.1.4-3+deb7u5.
