File 0229-vmware-vga-CVE-2014-3689-turn-off-h.patch of Package qemu-linux-user.7445
From 0282fa4d705990197b02677d17395c1aefe53830 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann <kraxel@redhat.com> Date: Mon, 6 Oct 2014 11:42:34 +0200 Subject: [PATCH] vmware-vga: CVE-2014-3689: turn off hw accel MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
