Description Agostino Sarubbo gentoo-dev 2014-04-16 07:45:54 UTC
From ${URL} :

An out of bounds memory access flaw was found in Qemu's IDE device model.
It leads to Qemu's memory corruption via buffer overwrite(4 bytes). It occurs
while executing IDE SMART commands.

A user on guest could use this flaw to corrupt Qemu process's memory on the

Upstream fix:

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

There was a comment on the mailing list about earlier stable branches:

> Should also be fixed in the stable branch of earlier releases. The bug

Can the Maintainers confirm if this is vulnerable in previous versions?
