libtiff: out-of-bounds write in the tiff2rgba tool

Multiple integer overflows in the (1) cvt_by_strip and (2) cvt_by_tile functions in the tiff2rgba tool in LibTIFF 4.0.6 and earlier, when -b mode is enabled, allow remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted TIFF image, which triggers an out-of-bounds write.

qemu-kvm: Out-of-bounds read when creating weird vga screen surface

Integer overflow in the VGA module in QEMU allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) by editing VGA registers in VBE mode.

Unspecified vulnerability in the Oracle VM VirtualBox component in Oracle Virtualization VirtualBox before 4.3.20 allows local users to affect integrity and availability via vectors related to VMSVGA virtual graphics device, a different vulnerability than CVE-2014-6588, CVE-2014-6589, CVE-2014-6595, and CVE-2015-0427.

qemu: incorrect banked access bounds checking in vga module

The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue.

libtiff: out-of-bounds write in _TIFFVGetField function

The _TIFFVGetField function in tif_dirinfo.c in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (out-of-bounds write) or execute arbitrary code via a crafted TIFF image.

Unspecified vulnerability in the Oracle VM VirtualBox component in Oracle Virtualization VirtualBox before 4.3.20 allows local users to affect integrity and availability via vectors related to VMSVGA virtual graphics device, a different vulnerability than CVE-2014-6588, CVE-2014-6590, CVE-2014-6595, and CVE-2015-0427.

Unspecified vulnerability in the Oracle VM VirtualBox component in Oracle Virtualization VirtualBox before 5.0.26 allows local users to affect availability via vectors related to Core.

Unspecified vulnerability in the Oracle VM VirtualBox component in Oracle Virtualization VirtualBox before 4.3.20 allows local users to affect integrity and availability via vectors related to VMSVGA virtual graphics device, a different vulnerability than CVE-2014-6589, CVE-2014-6590, CVE-2014-6595, and CVE-2015-0427.

Unspecified vulnerability in the Oracle VM VirtualBox component in Oracle Virtualization VirtualBox before 5.0.22 allows remote attackers to affect confidentiality via vectors related to Core.

xen: AMD FPU FIP/FDP/FOP leak workaround broken (XSA-172)

The fpu_fxrstor function in arch/x86/i387.c in Xen 4.x does not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allows local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-2076.

Unspecified vulnerability in the Oracle VM VirtualBox component in Oracle Virtualization VirtualBox before 4.1.34, before 4.2.26, and before 4.3.14 allows local users to affect availability via vectors related to Graphics driver (WDDM) for Windows guests.

xen: AMD FPU FIP/FDP/FOP leak workaround broken (XSA-172)

The xrstor function in arch/x86/xstate.c in Xen 4.x does not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allows local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-2076.

Unspecified vulnerability in the Oracle VM VirtualBox component in Oracle Virtualization VirtualBox before 3.2.24, 4.0.26, 4.1.34, 4.2.26, and 4.3.14 allows local users to affect confidentiality, integrity, and availability via unknown vectors related to Core, a different vulnerability than CVE-2014-2487.

bind: assertion failure in buffer.c while building responses to a specifically constructed request

buffer.c in named in ISC BIND 9 before 9.9.9-P3, 9.10.x before 9.10.4-P3, and 9.11.x before 9.11.0rc3 does not properly construct responses, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted query.

Unspecified vulnerability in the Oracle VM VirtualBox component in Oracle Virtualization VirtualBox prior to 3.2.18, 4.0.20, 4.1.28, and 4.2.18 allows local users to affect availability via unknown vectors related to Core.

Unspecified vulnerability in the Secure Global Desktop component in Oracle Virtualization All 4.6 releases including 4.63 and 4.7 prior to 4.71 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Web UI.

Unspecified vulnerability in Oracle VM VirtualBox 3.0, 3.1, 3.2, and 4.0 through 4.0.8 allows local users to affect confidentiality, integrity, and availability via unknown vectors related to Guest Additions for Windows.

nss: TLS CBC padding timing attack

The TLS implementation in Mozilla Network Security Services (NSS) does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, a related issue to CVE-2013-0169.
