Service hang via malformed MP3 parsing
Published Mar 31, 2021 · Updated Feb 13, 2025
Infinite-loop denial of service in Apache Tika 1.25 and earlier allows attackers to hang MP3Parser with a crafted or corrupt file. Apache has not published the malformed MP3 field, loop condition, or source-level operation that fails to terminate. The attacker must cause an affected deployment to parse the file; the resulting loop consumes processing capacity and can interrupt that parsing service.
