cirrus_bitblt_cputovideo does not check if memory region is safe

ISSUE DESCRIPTION In CIRRUSBLTMODEMEMSYSSRC mode the bitblit copy routine cirrusbitbltcputovideo fails to check wethehr the specified memory region is safe. IMPACT A malicious guest administrator can cause an out of bounds memory write, very likely exploitable as a privilege escalation. VULNERABL...

oob access in cirrus bitblt copy

ISSUE DESCRIPTION When doing bitblt copy backwards, qemu should negate the blit width. This avoids an oob access before the start of video memory. IMPACT A malicious guest administrator can cause an out of bounds memory access, leading to information disclosure or privilege escalation. VULNERABLE...

QEMU 'hw/display/cirrus_vga.c' Remote Code Execution Vulnerability

QEMU aka Quick Emulator is a set of simulation processor software developed by French programmer Fabrice Bellard. The software is fast and cross-platform. A remote code execution vulnerability exists in QEMU. An attacker could exploit this vulnerability to execute arbitrary code on the host's QEM...

xen-tools -- oob access in cirrus bitblt copy

The Xen Project reports: When doing bitblt copy backwards, qemu should negate the blit width. This avoids an oob access before the start of video memory. A malicious guest administrator can cause an out of bounds memory access, possibly leading to information disclosure or privilege escalation...
