Re: InfoSec Law for Dummies (or Engineers)
The Landscape itself was changed with first WannaCry in 2017 and then the Experian catastrophe - the effective Chernobyl of data breach stories.  After these two incidents, data breach and ransomware assumed a whole new face and import.  And corporate reaction took a beating after what Experian and brain-dead CEO stated in testimony.  We are MUCH more aware as a result of the downside beating a firm can take in private and public.

InfoSec Law for Dummies (or Engineers)
This article is a reminder that many engineers are woefully clueless when it comes to cyberlaw and some are clearly the wrong person to have in a room with lawyers after an "event".  It also calls to my attention that it seems the rift between the lawyers and security engineers is often vast.  At a minimum companies should keep documentation and provide training along the lines of "InfoSec Law for Dummies (or Engineers)" so everyone is speaking the same language.  Additionally, there should be regular face-to-face moments between an organization's cyberlaw team and the techs who do the work.  In the FLOSS realm, lawyers are often programmers themselves, and the language of law and tech among FLOSS coders is pretty fluid.  We're versed on the law through necessity.  However, in the corporate world, this seems far from common and the divide can be so vast as to be an "event" in and of itself.

CVE-2020-25596
PUBLISHED: 2020-09-23
An issue was discovered in Xen through 4.14.x. x86 PV guest kernels can experience denial of service via SYSENTER. The SYSENTER instruction leaves various state sanitization activities to software. One of Xen's sanitization paths injects a #GP fault, and incorrectly delivers it twice to the guest. T...
CVE-2020-25597
PUBLISHED: 2020-09-23
An issue was discovered in Xen through 4.14.x. There is mishandling of the constraint that once-valid event channels may not turn invalid. Logic in the handling of event channel operations in Xen assumes that an event channel, once valid, will not become invalid over the life time of a guest. Howeve...
CVE-2020-25598
PUBLISHED: 2020-09-23
An issue was discovered in Xen 4.14.x. There is a missing unlock in the XENMEM_acquire_resource error path. The RCU (Read, Copy, Update) mechanism is a synchronisation primitive. A buggy error path in the XENMEM_acquire_resource exits without releasing an RCU reference, which is conceptually similar...
CVE-2020-25599
PUBLISHED: 2020-09-23
An issue was discovered in Xen through 4.14.x. There are evtchn_reset() race conditions. Uses of EVTCHNOP_reset (potentially by a guest on itself) or XEN_DOMCTL_soft_reset (by itself covered by XSA-77) can lead to the violation of various internal assumptions. This may lead to out of bounds memory a...
CVE-2020-25600
PUBLISHED: 2020-09-23
An issue was discovered in Xen through 4.14.x. Out of bounds event channels are available to 32-bit x86 domains. The so called 2-level event channel model imposes different limits on the number of usable event channels for 32-bit x86 domains vs 64-bit or Arm (either bitness) ones. 32-bit x86 domains...
