  script_tag(name:"insight", value:"This update for rpm fixes the following issues:

  - Changed default package verification level to &#x27 none&#x27  to be compatible to
       rpm-4.14.1

  - Made illegal obsoletes a warning

  - Fixed a potential access of freed mem in ndb&#x27 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&#x27 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&#x27 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.");
