sol15912: Linux kernel driver vulnerabilities CVE-2014-3184, CVE-2014-3185, 
CVE-2014-3611, CVE-2014-3645, and CVE-2014-3646 

Security Advisory

Original Publication Date: 12/16/2014

Description

CVE-2014-3184

The report_fixup functions in the HID subsystem in the Linux kernel before 
3.16.2 might allow physically proximate attackers to cause a denial of service 
(out-of-bounds write) via a crafted device that provides a small report 
descriptor, related to (1) drivers/hid/hid-cherry.c, (2) drivers/hid/hid-kye.c, 
(3) drivers/hid/hid-lg.c, (4) drivers/hid/hid-monterey.c, 
(5) drivers/hid/hid-petalynx.c, and (6) drivers/hid/hid-sunplus.c.

CVE-2014-3185

Multiple buffer overflows in the command_port_read_callback function in 
drivers/usb/serial/whiteheat.c in the Whiteheat USB Serial Driver in the Linux 
kernel before 3.16.2 allow physically proximate attackers to execute arbitrary 
code or cause a denial of service (memory corruption and system crash) via a
crafted device that provides a large amount of (1) EHCI or (2) XHCI data 
associated with a bulk response.

CVE-2014-3611

Race condition in the __kvm_migrate_pit_timer function in arch/x86/kvm/i8254.c
in the KVM subsystem in the Linux kernel through 3.17.2 allows guest OS users 
to cause a denial of service (host OS crash) by leveraging incorrect PIT 
emulation.

CVE-2014-3645

arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.12 does 
not have an exit handler for the INVEPT instruction, which allows guest OS 
users to cause a denial of service (guest OS crash) via a crafted application.

CVE-2014-3646

arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel through 3.17.2 does
not have an exit handler for the INVVPID instruction, which allows guest OS 
users to cause a denial of service (guest OS crash) via a crafted application.

Impact

An attacker may be able to gain access to unauthorized information, perform 
unauthorized modification of data, or cause disruption of services. 
CVE-2014-3184 and CVE-2014-3185 require physical access to the device. 
CVE-2014-3611, CVE-2014-3645, and CVE-2014-3646 are considered local, as they 
are exploitable only by an authenticated user.

Status

F5 Product Development has assigned ID 492735, ID 492751, ID 492755, and ID 
492761 (BIG-IP), ID 496037 and ID 496042 (BIG-IQ), ID 496045 and ID 496044 
(Enterprise Manager), and ID 492564 (WebSafe) to these vulnerabilities, and 
has evaluated the currently supported releases for potential vulnerability.

Recommended action

If the previous table lists a version in the Versions known to be not 
vulnerable column, you can eliminate this vulnerability by upgrading to the
listed version. If the table does not list any version in the column, then no 
upgrade candidate currently exists.

To mitigate vulnerabilities CVE-2014-3185 and CVE-2014-3184, maintain affected 
products in a secure location, which limits physical access to the unit. To
mitigate vulnerabilities CVE-2014-3611, CVE-2014-3645, and CVE-2014-3646, limit 
host and guest login to trusted users.
