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 Tika's ICNSParser, MP3Parser, MP4Parser, SAS7BDATParser, OneNoteParser and ImageParser. Apache Tika users should upgrade to 1.24.1 or later. The vulnerabilities in the MP4Parser were partially fixed by upgrading the com.googlecode:isoparser:1.1.22 dependency to org.tallison:isoparser:1.9.41.2. For unrelated security reasons, we upgraded org.apache.cxf to 3.3.6 as part of the 1.24.1 release.
A carefully crafted or corrupt zip file can cause an OOM in Apache Tika's RecursiveParserWrapper in versions 1.7-1.21. Users should upgrade to 1.22 or later.
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 package/compressed file that, when unzipped/uncompressed yields the same file (a quine), causes a StackOverflowError in Apache Tika's RecursiveParserWrapper in versions 1.7-1.21. Apache Tika users should upgrade to 1.22 or later.
In Apache Tika 1.19 (CVE-2018-11761), we added an entity expansion limit for XML parsing. However, Tika reuses SAXParsers and calls reset() after each parse, which, for Xerces2 parsers, as per the documentation, removes the user-specified SecurityManager and thus removes entity expansion limits after the first parse. Apache Tika versions from 0.1 to 1.19 are therefore still vulnerable to entity expansions which can lead to a denial of service attack. Users should upgrade to 1.19.1 or later.
In Apache Tika 0.1 to 1.18, the XML parsers were not configured to limit entity expansion. They were therefore vulnerable to an entity expansion vulnerability which can lead to a denial of service attack.
