Denial of service via malformed parser input
Published Apr 27, 2020 · Updated Aug 4, 2024
Denial of service in Apache Tika 1.24 and earlier allows attackers to crash or hang applications by submitting crafted files. OneNotePtr called System.exit for a nonzero reserved field and repeated deserialization when no bytes were consumed, while TikaInputStream trusted unreliable skip results. Exploitation requires a target application or service to parse an attacker-controlled file; outcomes are limited to process termination, memory exhaustion, or an infinite loop.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=Up to 1.24
