An update that solves three vulnerabilities, contains two
features and has one errata is now available.

Description:

This update for rpm fixes the following issues:

- Changed default package verification level to 'none' to be compatible to
rpm-4.14.1
- Made illegal obsoletes a warning
- Fixed a potential access of freed mem in ndb's glue code (bsc#1179416)
- Added support for enforcing signature policy and payload verification
step to transactions (jsc#SLE-17817)
- Added :humansi and :hmaniec query formatters for human readable output
- Added query selectors for whatobsoletes and whatconflicts
- Added support for sorting caret higher than base version
- rpm does no longer require the signature header to be in a contiguous
region when signing (bsc#1181805)

Security fixes:

- CVE-2021-3421: 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 (bsc#1183543)

- CVE-2021-20271: A flaw was found in RPM's signature check functionality
when reading a package file. This flaw allows an attacker who can
convince a victim to install a seemingly verifiable package, whose
signature header was modified, to cause RPM database corruption and
execute code. The highest 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.
