Hi,

The following vulnerability was published for nekohtml.

CVE-2022-24839[0]:
| org.cyberneko.html is an html parser written in Java. The fork of
| `org.cyberneko.html` used by Nokogiri (Rubygem) raises a
| `java.lang.OutOfMemoryError` exception when parsing ill-formed HTML
| markup. Users are advised to upgrade to `>= 1.9.22.noko2`. Note:
| The upstream library `org.cyberneko.html` is no longer maintained.
| Nokogiri uses its own fork of this library located at
| https://github.com/sparklemotion/nekohtml and this CVE applies only to
| that fork. Other forks of nekohtml may have a similar vulnerability.
