This\nissue specifically occurs when processing encrypted query data\nreceived from remote clients.\n\n## Impact\n\nAn attacker with knowledge of this vulnerability could craft and send\nspecially designed encrypted queries to targeted ODOH servers running\nwith odoh-rs. Upon successful exploitation, the server will crash\nabruptly, disrupting its normal operation and rendering the service\ntemporarily unavailable.\n\n## Patches\n\nUsers are encouraged to update their odoh-rs's rust crate to v1.0.2.\n\n## Affected packages\n\n- `odoh-rs >= 0.0.0-0, < 1.0.2`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `odoh-rs 1.0.2`","depth":"sunlit","depthScore":33,"depthScoreParts":{"impact":32.5,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
