Summary
Important: pcs security update
Details

The pcs packages provide a command-line configuration system for the Pacemaker and Corosync utilities.

Security Fix(es):

  • rubygem-rack: Rack QueryParser has an unsafe default allowing params_limit bypass via semicolon-separated parameters (CVE-2025-59830)
  • rack: Rack's unbounded multipart preamble buffering enables DoS (memory exhaustion) (CVE-2025-61770)
  • rack: Rack's multipart parser buffers large non?file fields entirely in memory, enabling DoS (memory exhaustion) (CVE-2025-61771)
  • rack: Rack memory exhaustion denial of service (CVE-2025-61772)
  • rubygem-rack: Unbounded read in Rack::Request form parsing can lead to memory exhaustion (CVE-2025-61919)
