threat from this vulnerability is to data integrity, confidentiality, and system availability (bsc#1183545)
- CVE-2021-20266: A flaw was found in RPM's hdrblobInit() in lib/header.c. This flaw allows an attacker
who can modify the rpmdb to cause an out-of-bounds read. The highest threat from this vulnerability
is to system availability.
