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 ioport array overflow
ISSUE DESCRIPTION The code in qemu which implements ioport read/write looks up the specified ioport address in a dispatch table. The argument to the dispatch function is a uint32t, and is used without a range check, even though the table has entries for only 2^16 ioports. When qemu is used as a...
Unrestricted qemu logging
ISSUE DESCRIPTION When the libxl toolstack launches qemu for HVM guests, it pipes the output of stderr to a file in /var/log/xen. This output is not rate-limited in any way. The guest can easily cause qemu to print messages to stderr, causing this file to become arbitrarily large. IMPACT The disk...
