Incoming details.
Comment 1 John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2021-05-21 01:15:00 UTC
Now publicly disclosed.

Description:

"hivex is a library for reading and writing Windows Registry (hive)
files.  Jeremy Galindo, Sr Security Engineer at Datto.com found a flaw
caused by a lack of bounds checking in hivex_open which would cause
hivex to read memory beyond its normal bounds and/or cause the program
to crash."
