The hvm_msr_read_intercept function in arch/x86/hvm/hvm.c in Xen 4.1 through 4.4.x uses an improper MSR range for x2APIC emulation, which allows local HVM guests to cause a denial of service (host crash) or read data from the hypervisor or other guests via unspecified vectors.

CVE-2014-7188 [HIGH] CVE-2014-7188 kernel: xen: Improper MSR range used for x2APIC emulation (xsa108)
CVE-2014-7188 kernel: xen: Improper MSR range used for x2APIC emulation (xsa108)
The MSR range specified for APIC use in the x2APIC access model spans
256 MSRs. Hypervisor code emulating read and write accesses to these
MSRs erroneously covered 1024 MSRs. While the write emulation path is
written such that accesses to the extra MSRs would not have any bad
effect (they end up being no-ops), the read path would (attempt to)
access memory beyond the single page set up for APIC emulation.
A buggy or malicious HVM guest can crash the host or read data
relating to other guests or the hypervisor itself.

CVE-2014-4336 cups-filters: incomplete fix for CVE-2014-2707
According to Sebastian Krahmer, the initial fix for CVE-2014-2707 (bug #1083326) is incomplete:
"
This issue was reported as fixed in 1.0.51:
http://bzr.linuxfoundation.org/loggerhead/openprinting/cups-filters/revision/7188
http://bzr.linuxfoundation.org/loggerhead/openprinting/cups-filters/revision/7189
but it was found that the fix was incomplete with the full fix in 1.0.53:
http://bzr.linuxfoundation.org/loggerhead/openprinting/cups-filters/revision/7194
"
The CVE-2014-2707 flaw is regarding the cups-browsed daemon being manipulated to execute arbitrary commands via malicious broadcast packets.
