Among the speakers at last week’s (ISC)2 Congress were a pair of security and compliance leaders who helped build out a major cloud project for Starbucks. Matt Wells and Scott Schwan, founders of compliance automation startup Shujinko, were called on by Starbucks several years back to build out the team and processes necessary to support Starbucks’ mobile app with fully PCI-compliant and secure cloud architecture measured against standards established by the Center for Internet Security (CIS).
“Basically, in about nine to 12 months, with 20 engineers, we were able to build a highly automated, scalable, repeatable environment that Starbucks could use to back everything they’d want to roll out, and they used that as a foundation to then start moving other applications to the public cloud,” explained Wells, who serves as CTO.
Wells and Schwan, CEO, delved into the details of their work at Starbucks to offer the crowd tips on how to bake compliance into their own cloud architecture and scale DevSecOps in the process. We offer the highlights from their insights, in their own words.

In the Linux kernel 5.3.11, mounting a crafted btrfs image twice can cause an rwsem_down_write_slowpath use-after-free because (in rwsem_can_spin_on_owner in kernel/locking/rwsem.c) rwsem_owner_flags returns an already freed pointer,
In the Linux kernel 5.0.21, a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call.
An attacker may use a specially crafted message to force Relion 650 series (versions 126.96.36.199 and prior) or Relion 670 series (versions 188.8.131.52, 184.108.40.206, 220.127.116.11 and prior) to reboot, which could cause a denial of service.
An attacker could use specially crafted paths in a specific request to read or delete files from Relion 670 Series (versions 1p1r26, 18.104.22.168, 22.214.171.124, RES670 126.96.36.199, 188.8.131.52, and prior) outside the intended directory.
The Linux kernel through 5.3.13 on powerpc allows Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c.
