From d36794af8ad947a2d3eb33df2137980366b63d49 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Wed, 4 Mar 2015 17:55:51 +0000 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.
