- Security database references:
- In Mitre's CVE dictionary: CVE-2015-2044, CVE-2015-2045, CVE-2015-2151.
- More information:
Multiple security issues have been found in the Xen virtualisation solution:
Information leak via x86 system device emulation.
Information leak in the HYPERVISOR_xen_version() hypercall.
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 http://xenbits.xen.org/xsa/advisory-124.html for further information.
For the stable distribution (wheezy), these problems have been fixed in version 4.1.4-3+deb7u5.
For the unstable distribution (sid), these problems will be fixed soon.
We recommend that you upgrade your xen packages.
