| Vetor | AV:L/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
QEMU versions prior to the version that includes the fix for this issue
Xen versions 4.5.x and earlier
Description
The issue is related to a heap-based buffer overflow in the IDE subsystem of QEMU, which is used in Xen. This overflow can occur when the container has a CDROM drive enabled, allowing local guest users to execute arbitrary code on the host via unspecified ATAPI commands. The vulnerability can be exploited by a local attacker to gain control over the host system.
Recommendations
For Xen versions 4.5.x and earlier, update to a version that includes the fix for this issue.
For QEMU, update to a version that includes the fix for this issue.
As a temporary workaround, consider disabling the CDROM drive in the container to minimize the risk of exploitation.
