The RPM Package Manager (RPM) is a powerful package management system capability as below

Security Fix(es):

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.(CVE-2021-20266)

A flaw was found in the RPM package in the read functionality. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package or compromise an RPM repository, to cause RPM database corruption. The highest threat from this vulnerability is to data integrity. This flaw affects RPM versions before 4.17.0-alpha.(CVE-2021-3421)
