-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.
-
