CVE-2016-10028 [MEDIUM] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
Zhenhao Hong discovered that QEMU incorrectly handled the Virtio GPU
device. An attacker inside the guest could use this issue to cause QEMU to
crash, resulting in a denial of service. This issue only affected Ubuntu
16.04 LTS and Ubuntu 16.10. (CVE-2016-10028, CVE-2016-10029)
Li Qiang discovered that QEMU incorrectly handled the 6300esb watchdog. A
privileged attacker inside the guest could use this issue to cause QEMU to
crash, resulting in a denial of service. (CVE-2016-10155)
Li Qiang discovered that QEMU incorrectly handled the i.MX Fast Ethernet
Controller. A privileged attacker inside the guest could use this issue to

CVE-2016-9913 CVE-2016-9914 CVE-2016-9915 CVE-2016-9916 Qemu: 9pfs: memory leakage via proxy/handle callbacks
Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9
File System(9pfs) support, is vulnerable to memory leakage issue. It could
occur via its '9p-handle' or '9p-proxy' backend drivers as they do not free
their respective allocated data objects.
A privileged user inside guest could use this flaw to leak host memory, thus
affecting other services on the host and/or potentially crash the Qemu process
on the host.

CVE-2016-9844 unzip: methbuf[] buffer overflow in zipinfo's zi_short()
A buffer overflow vulnerability was found in zipinfo (part of the unzip package) when the compression method in the central directory file header is greater then 999.
The original Ubuntu bug report:
https://bugs.launchpad.net/ubuntu/+source/unzip/+bug/1643750
Proposed fix:
http://seclists.org/oss-sec/2016/q4/600
References:

Discussion:
This bug is pretty much identical to the similar problem fixed in unzip's list_files() - see CVE-2014-9913 / bug 1401865.
This issue is caught by FORTIFY_SOURCE, limiting its impact to a crash of the zipinfo command. Therefore, the issue is not planned to be corrected in the unzip packages in Red Hat Enterprise Linux 5, 6, and 7.

CVE-2014-9913 unzip: methbuf[] buffer overflow in unzip's list_files()
A buffer overflow vulnerability was found in "unzip -l" via list_files() in list.c. This issue is caught by fortify source.

Discussion:
This issue was previously reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=1191136#c1
The issue was already corrected in Fedora unzip packages. This issue is not planned to be corrected in the unzip packages in Red Hat Enterprise Linux 5, 6, and 7, as the problem is caught by FORTIFY_SOURCE, limiting impact to a crash of the unzip command.
