Package        : ruby-nokogiri
Version        : 1.6.8.1-1+deb9u2
CVE ID         : CVE-2022-24836
Debian Bug     : #1009787

It was discovered that there was a potential denial of service attack
in ruby-nokogiri, a HTML, XML, SAX etc. parser written in/for the Ruby
programming language. This was caused by the use of inefficient
regular expressions that were susceptible to excessive backtracking.

For Debian 9 "Stretch", this problem has been fixed in version
1.6.8.1-1+deb9u2.

We recommend that you upgrade your ruby-nokogiri packages.
