Use-after-free in libxml2 via Nokogiri::XML::Reader
Nokogiri upgrades its dependency libxml2 as follows:
libxml2 v2.11.7 and v2.12.5 address the following vulnerability:
CVE-2024-25062 / https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-25062
Please note that this advisory only applies to the CRuby implementation of Nokogiri, and only if the packaged libraries are being used. If you've overridden defaults at installation time to use system libraries instead of packaged libraries, you should instead pay attention to your distro's libxml2 release announcements.
JRuby users are not affected.
The Nokogiri maintainers have evaluated this as Moderate.
From the CVE description, this issue applies to the xmlTextReader
module (which underlies
Nokogiri::XML::Reader
):
Upgrade to Nokogiri ~> 1.15.6
or >= 1.16.2
.
Users who are unable to upgrade Nokogiri may also choose a more complicated mitigation: compile and link Nokogiri against patched external libxml2 libraries which will also address these same issues.
