+Subject: [PATCH 3/3] cirrus: add blit_is_unsafe call to
cirrus_bitblt_cputovideo
+
+CIRRUS_BLTMODE_MEMSYSSRC blits do NOT check blit destination
+and blit width, at all. Oops. Fix it.
+
+Security impact: high.
+
+The missing blit destination check allows to write to host memory.
+Basically same as CVE-2014-8106 for the other blit variants.
+
+The missing blit width check allows to overflow cirrus_bltbuf,
+with the attractive target cirrus_srcptr (current cirrus_bltbuf write
+position) being located right after cirrus_bltbuf in CirrusVGAState.
+
+Due to cirrus emulation writing cirrus_bltbuf bytewise the attacker
+hasn't full control over cirrus_srcptr though, only one byte can be
+changed. Once the first byte has been modified further writes land
+elsewhere.
+
+[ This is CVE-2017-2620 / XSA-209 - Ian Jackson ]

+This patch fixed a problem that was introduced in commit eb700029.
+
+When net_rx_pkt_attach_iovec() calls eth_strip_vlan()
+this can result in pkt->ehdr_buf being overflowed, because
+ehdr_buf is only sizeof(struct eth_header) bytes large
+but eth_strip_vlan() can write
+sizeof(struct eth_header) + sizeof(struct vlan_header)
+bytes into it.
+
+Devices affected by this problem: vmxnet3.
