Affected Products:
  • SUSE Linux Enterprise Module for SUSE Manager Server 4.2
  • SUSE Linux Enterprise Module for SUSE Manager Proxy 4.2
  • SUSE Linux Enterprise Module for Python2 15-SP3
  • SUSE Linux Enterprise Module for Public Cloud 15-SP3
  • SUSE Linux Enterprise Module for Development Tools 15-SP3
  • SUSE Linux Enterprise Module for Basesystem 15-SP3

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.
