From 56b6131a153668bbb77e1b9b7e86379c41f8fdf9 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Mon, 6 Oct 2014 11:42:34 +0200 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.
