CVE-2022-33879: Apache Tika: Incomplete fix and new regex DoS in
StandardsExtractingContentHandler

Severity: low

Description:

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.
