CVE-2015-2151

CVE-2015-2151 affects the Xen x86 CPU emulator (xen only) where instructions with segment overrides are not properly ignored for register operands. A local guest user could read arbitrary data from other guests, trigger memory corruption causing a Denial of Service, or potentially escalate privil...

Debian DSA-3181-1 : xen - security update

Multiple security issues have been found in the Xen virtualisation solution : - CVE-2015-2044 Information leak via x86 system device emulation. - CVE-2015-2045 Information leak in the HYPERVISORxenversion hypercall. - CVE-2015-2151 Missing input sanitising in the x86 emulator could result in...

Hypervisor memory corruption due to x86 emulator flaw

ISSUE DESCRIPTION Instructions with register operands ignore eventual segment overrides encoded for them. Due to an insufficiently conditional assignment such a bogus segment override can, however, corrupt a pointer used subsequently to store the result of the instruction. IMPACT A malicious gues...

qemu: cirrus: insufficient blit region checks

It was found that the Cirrus blit region checks were insufficient. A privileged guest user could use this flaw to write outside of VRAM-allocated buffer boundaries in the host's QEMU process address space with attacker-provided data...

[SECURITY] Fedora 20 Update: qemu-1.6.2-13.fc20

QEMU is a generic and open source processor emulator which achieves a good emulation speed by using dynamic translation. QEMU has two operating modes: Full system emulation. In this mode, QEMU emulates a full system for example a PC, including a processor and various peripherials. It can be used ...

SUSE-SU-2015:0349-1 Security update for qemu

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/cirrusvga.c in QEMU allowed local guest users to execute arbitrary code via vectors related to blit regions. CVE-2014-784...
