The initial fixes in CVE-2022-30126 and CVE-2022-30973 for regexes in the StandardsExtractingContentHandler were insufficient, and we found a separate, new regex DoS in a different regex in the StandardsExtractingContentHandler. These are now fixed in 1.28.4 and 2.4.1.
A carefully crafted or corrupt file may trigger an infinite loop in Tika's MP3Parser
A carefully crafted or corrupt file may trigger a System.exit in Tika's OneNote Parser. Crafted or corrupted files can also cause out of memory errors and/or infinite loops.
In Apache Tika 1.19 to 1.21, a carefully crafted 2003ml or 2006ml file could consume all available SAXParsers in the pool and lead to very long hangs. Apache Tika users should upgrade to 1.22 or later.
A carefully crafted or corrupt sqlite file can cause an infinite loop in Apache Tika's SQLite3Parser in versions 1.8-1.19.1 of Apache Tika.
Tika reuses SAXParsers and calls reset() after each parse; the parser ignores entity expansion limits after the first parse.
In Apache Tikato, a carefully crafted file can trigger an infinite loop in the IptcAnpaParser.
In Apache Tika, the XML parsers were not configured to limit entity expansion. They were therefore vulnerable to an entity expansion vulnerability which can lead to a DoS.
A carefully crafted (or fuzzed) file can trigger an infinite loop in Apache Tika BPGParser.
A carefully crafted (or fuzzed) file can trigger an infinite loop in Apache Tika ChmParser.
Apache Tika allows Java code execution for serialized objects embedded in MATLAB files. The issue exists because Tika invokes JMatIO to do native deserialization.
