Subject: [Qemu-devel] [PATCH 0/2] Qemu: scsi: esp: check command buffer input length
Date: Thu, 19 May 2016 16:09:29 +0530 [thread overview]
Message-ID: <1463654371-11169-1-git-send-email-ppandit@redhat.com> (raw)
From: Prasad J Pandit <pjp@fedoraproject.org>
Hello,
The ESP 53C9X Fast SCSI Controller(FSC) comes with an internal 16-byte
FIFO buffer. It is used to handle command and data transfer between
controller and the bus. Couple of OOB write access issues were found
and reported in its emulation by Mr Li Qiang of 360.cn Inc.
Please see below are the proposed patches to fix these issues.
Thank you.
