CVSS v2.0
6.9
Média
| Vetor | AV:L/AC:M/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
QEMU versions prior to 2.3.1
Linux kernel versions prior to 2.6.33
Description
The issue is caused by a buffer overflow in the
pit ioport read function of the QEMU emulator, which does not properly distinguish between read lengths and write lengths. This could allow a local attacker to execute arbitrary code on the host operating system by triggering the use of an invalid index. The vulnerability can be exploited by guest OS users, potentially leading to the execution of arbitrary code on the host OS.Recommendations
For QEMU versions prior to 2.3.1, update to version 2.3.1 or later to resolve the issue.
For Linux kernel versions prior to 2.6.33, update to version 2.6.33 or later to resolve the issue.
As a temporary workaround, consider restricting access to virtual machines hosted on affected systems to trusted users only, and avoid allowing untrusted users to access the virtual machine.
