+From 693fd2acdf14dd86c0bf852610f1c2cca80a74dc Mon Sep 17 00:00:00 2001
+From: Felipe Franciosi <felipe@nutanix.com>
+Date: Thu, 23 Jan 2020 12:44:59 +0000
+Subject: [PATCH] iscsi: Cap block count from GET LBA STATUS (CVE-2020-1711)
+
+When querying an iSCSI server for the provisioning status of blocks (via
+GET LBA STATUS), Qemu only validates that the response descriptor zero's
+LBA matches the one requested. Given the SCSI spec allows servers to
+respond with the status of blocks beyond the end of the LUN, Qemu may
+have its heap corrupted by clearing/setting too many bits at the end of
+its allocmap for the LUN.
+
+A malicious guest in control of the iSCSI server could carefully program
+Qemu's heap (by selectively setting the bitmap) and then smash it.
+
+This limits the number of bits that iscsi_co_block_status() will try to
+update in the allocmap so it can't overflow the bitmap.
+
+Fixes: CVE-2020-1711
