+Subject: [PATCH] vmware-vga: CVE-2014-3689: turn off hw accel
+
+Quick & easy stopgap for CVE-2014-3689:  We just compile out the
+hardware acceleration functions which lack sanity checks.  Thankfully
+we have capability bits for them (SVGA_CAP_RECT_COPY and
+SVGA_CAP_RECT_FILL), so guests should deal just fine, in theory.
+
+Subsequent patches will add the missing checks and re-enable the
+hardware acceleration emulation.
+
+Upstream-Status: Backport
