Citrix XenServer Multiple Security Updates (CTX201145)

A number of security vulnerabilities have been identified in Citrix XenServer that may allow a malicious administrator of a guest VM to crash the host. These vulnerabilities affect all currently supported versions of Citrix XenServer up to and including Citrix XenServer 6.5 Service Pack 1...

USN-2630-1 qemu, qemu-kvm vulnerabilities

Matt Tait discovered that QEMU incorrectly handled the virtual PCNET driver. A malicious guest could use this issue to cause a denial of service, or possibly execute arbitrary code on the host as the user running the QEMU process. In the default installation, when QEMU is used with libvirt,...

DEBIAN-CVE-2015-4104

Xen 3.3.x through 4.5.x does not properly restrict access to PCI MSI mask bits, which allows local x86 HVM guest users to cause a denial of service unexpected interrupt and host crash via unspecified vectors...

Code injection

PCI MSI mask bits inadvertently exposed to guests

ISSUE DESCRIPTION The mask bits optionally available in the PCI MSI capability structure are used by the hypervisor to occasionally suppress interrupt delivery. Unprivileged guests were, however, nevertheless allowed direct control of these bits. IMPACT Interrupts may be observed by Xen at...

qemu: vnc: insufficient bits_per_pixel from the client sanitization

An uninitialized data structure use flaw was found in the way the setpixelformat function sanitized the value of bitsperpixel. An attacker able to access a guest's VNC console could use this flaw to crash the guest...

Windows-8.1-ahcache.sys

On Windows 8.1 update the system call NtApphelpCacheControl the code is actually in ahcache.sys allows application compatibility data to be cached for quick reuse when new processes are created. A normal user can query the cache but cannot add new cached entries as the operation is restricted to...

UBUNTU-CVE-2014-8129

LibTIFF 4.0.3 allows remote attackers to cause a denial of service out-of-bounds write or possibly have unspecified other impact via a crafted TIFF image, as demonstrated by failure of tifnext.c to verify that the BitsPerSample value is 2, and the t2psamplelabsignedtounsigned function in tiff2pdf...

OracleVM 3.1 : xen (OVMSA-2012-0039)

The remote OracleVM system is missing necessary patches to address critical security updates : - console: bounds check whenever changing the cursor due to an escape code The device model used by fully virtualised HVM domains, qemu, does not properly handle escape VT100 sequences when emulating...

DEBIAN-CVE-2014-8545

libavcodec/pngdec.c in FFmpeg before 2.4.2 accepts the monochrome-black format without verifying that the bits-per-pixel value is 1, which allows remote attackers to cause a denial of service out-of-bounds access or possibly have unspecified other impact via crafted PNG data...

DEBIAN-CVE-2014-8544

libavcodec/tiff.c in FFmpeg before 2.4.2 does not properly validate bits-per-pixel fields, which allows remote attackers to cause a denial of service out-of-bounds access or possibly have unspecified other impact via crafted TIFF data...

DEBIAN-CVE-2014-8541

libavcodec/mjpegdec.c in FFmpeg before 2.4.2 considers only dimension differences, and not bits-per-pixel differences, when determining whether an image size has changed, which allows remote attackers to cause a denial of service out-of-bounds access or possibly have unspecified other impact via...
