The sort_ranges() comparator in soup-message-headers.c truncates a 64-bit subtraction result to 32-bit int, flipping the sign for range offsets differing by more than INT_MAX. This causes silent omission of requested byte ranges from HTTP 206 Partial Content responses on resources larger than approximately 2 GB.\n\n## Affected\n\n- `libsoup3 (all versions)`\n- `libsoup (all versions)`\n- `gnome-clocks (all versions)`\n- `libsoup (all versions)`\n- `container-tools:rhel8/podman (all versions)`\n- `libsoup (all versions)`\n- `libsoup (all versions)`\n- `podman (all versions)`\n- `podman (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nNo mitigation is available for this vulnerability.","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
