QEMU was updated to fix various bugs and security issues.
Following security issues were fixed: CVE-2014-8106: Heap-based buffer

allowed local guest users to execute arbitrary code via vectors related to
blit regions.
CVE-2014-7840: The host_from_stream_offset function in arch_init.c in
QEMU, when loading RAM during migration, allowed remote attackers to
execute arbitrary code via a crafted (1) offset or (2) length value in
savevm data.
Also a bug was fixed where qemu-img convert could occasionaly corrupt
images. (bsc#908380)
