CVE-2024-12084: Rsync: heap buffer overflow in rsync due to improper checksum length handling

A heap-based buffer overflow flaw was found in the rsync daemon. This issue is due to improper handling of attacker-controlled checksum lengths (s2length) in the code. When MAX_DIGEST_LEN exceeds the fixed SUM_LENGTH (16 bytes), an attacker can write out of bounds in the sum2 buffer.

Security readout for executives and security teams

CVE-2024-12084 is a critical rsync daemon memory-corruption flaw. A remote, unauthenticated attacker may be able to compromise confidentiality, integrity, and availability where vulnerable rsync daemon service is exposed. The business priority is to find internet- or partner-facing rsync daemons and apply vendor guidance quickly. Highest exposure is systems running rsync in daemon mode, especially reachable over networks. The bundle names rsync 3.2.7 and 3.3.0, and Red Hat marks RHEL 10 package rsync 0:3.4.1-2.el10 affected. RHEL 6-9 and OpenShift Container Platform 4 are listed as unaffected in the provided data. Prioritize this as critical for any environment exposing rsync daemon services. Network reachability, no required authentication, and full CIA impact create material business risk. If rsync is internal-only and tightly filtered, urgency remains high but sequencing can follow exposure. Mitigation focus: Inventory systems running rsync daemon mode, prioritizing internet-facing services.; Apply vendor updates or errata where available, including Red Hat guidance for affected packages.; Restrict rsync daemon access to trusted networks until remediation is complete..
