Synopsis

The remote SUSE host is missing one or more security updates.

Description

QEMU was updated to fix various bugs and security issues.

Following security issues were fixed: CVE-2014-8106: Heap-based buffer overflow in the Cirrus VGA emulator (hw/display/cirrus_vga.c) in QEMU 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)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
