NVD Description

Note: Versions mentioned in the description apply only to the upstream spausedd package and not the spausedd package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

A heap-based buffer overflow was found in Corosync's Totem Process Group (totempg) message reassembly. When processing fragmented multicast messages, the buffer used to reassemble fragments lacks a runtime bounds check in release builds. A network-adjacent attacker able to send crafted multicast protocol messages to the cluster could cause a heap buffer overflow with attacker-controlled data. This can crash the Corosync daemon, causing a denial of service to the entire cluster, and may potentially allow further exploitation given sufficient heap-corruption control.
