| Vector | AV:L/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
XenSource Xen Para-Virtualized Framebuffer (PVFB) versions 3.0 through 3.0.3
Description
The issue is related to a buffer overflow in the backend framebuffer, allowing local users to cause a denial of service (SDL crash) and possibly execute arbitrary code via "bogus screen updates." This is due to missing validation of the
format of messages.Recommendations
For versions 3.0 through 3.0.3, consider disabling the framebuffer functionality as a temporary workaround until a patch is available. Restrict access to the framebuffer to minimize the risk of exploitation. Avoid using the framebuffer for critical operations until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
