Nokogiri updates packaged libxml2 to 2.13.6 to resolve CVE-2025-24928 and CVE-2024-56171 ## Summary Nokogiri v1.18.3 upgrades its dependency libxml2 to [v2.13.6](https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.13.6). libxml2 v2.13.6 addresses: - CVE-2025-24928 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/847 - CVE-2024-56171 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/828 ## Impact ### CVE-2025-24928 Stack-buffer overflow is possible when reporting DTD validation errors if the input contains a long (~3kb) QName prefix. ### CVE-2024-56171 Use-after-free is possible during validation against untrusted XML Schemas (.xsd) and, potentially, validation of untrusted documents against trusted Schemas if they make use of `xsd:keyref` in combination with recursively defined types that have additional identity constraints.

Nokogiri updates packaged libxml2 to v2.13.8 to resolve CVE-2025-32414 and CVE-2025-32415 ## Summary Nokogiri v1.18.8 upgrades its dependency libxml2 to [v2.13.8](https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.13.8). libxml2 v2.13.8 addresses: - CVE-2025-32414 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/889 - CVE-2025-32415 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/890 ## Impact ### CVE-2025-32414: No impact In libxml2 before 2.13.8 and 2.14.x before 2.14.2, out-of-bounds memory access can occur in the Python API (Python bindings) because of an incorrect return value. This occurs in xmlPythonFileRead and xmlPythonFileReadRaw because of a difference between bytes and characters. **There is no impact** from this CVE for Nokogiri users. ### CVE-2025-32415: Low impact In libxml2 before 2.13.8 and 2.14.x before 2.14.2, xmlSchemaIDCFillNodeTables in xmlschemas.c has a heap-based buffer under-read. To exploit this, a crafted XML document must be validated against an XML schema with certain identity constraints, or a crafted XML schema must be used. In the upstream issue, further context is provided by the maintainer: > The bug affects validation against untrusted XML Schemas (.xsd) > and validation of untrusted documents against trusted Schemas if > they make use of xsd:keyref in combination with recursively > defined types that have additional identity constraints. MITRE has published a severity score of 2.9 LOW (CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L) for this CVE.

This link is maintained to preserve external references. # Original Description ## Summary Nokogiri v1.18.3 upgrades its dependency libxml2 to [v2.13.6](https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.13.6). libxml2 v2.13.6 addresses: - CVE-2025-24928 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/847 - CVE-2024-56171 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/828 ## Impact ### CVE-2025-24928 Stack-buffer overflow is possible when reporting DTD validation errors if the input contains a long (~3kb) QName prefix. ### CVE-2024-56171 Use-after-free is possible during validation against untrusted XML Schemas (.xsd) and, potentially, validation of untrusted documents against trusted Schemas if they make use of `xsd:keyref` in combination with recursively defined types that have additional identity constraints.

Nokogiri patches vendored libxml2 to resolve multiple CVEs ## Summary Nokogiri v1.18.9 patches the vendored libxml2 to address CVE-2025-6021, CVE-2025-6170, CVE-2025-49794, CVE-2025-49795, and CVE-2025-49796. ## Impact and severity ### CVE-2025-6021 A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input. NVD claims a severity of 7.5 High (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Fixed by applying https://gitlab.gnome.org/GNOME/libxml2/-/commit/17d950ae ### CVE-2025-6170 A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections. NVD claims a severity of 2.5 Low (CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L) Fixed by applying https://gitlab.gnome.org/GNOME/libxml2/-/commit/5e9ec5c1 ### CVE-2025-49794 A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the <sch:name path="..."/> schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program's crash using libxml or other possible undefined behaviors. NVD claims a severity of 9.1 Critical (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H) Fixed by applying https://gitlab.gnome.org/GNOME/libxml2/-/commit/81cef8c5 ### CVE-2025-49795 A NULL pointer dereference vulnerability was found in libxml2 when processing XPath XML expressions. This flaw allows an attacker to craft a malicious XML input to libxml2, leading to a denial of service. NVD claims a severity of 7.5 High (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Fixed by applying https://gitlab.gnome.org/GNOME/libxml2/-/commit/62048278 ### CVE-2025-49796 A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to sensitive data being corrupted in memory. NVD claims a severity of 9.1 Critical (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H) Fixed by applying https://gitlab.gnome.org/GNOME/libxml2/-/commit/81cef8c5 ## Affected Versions - Nokogiri < 1.18.9 when using CRuby (MRI) with vendored libxml2 ## Patched Versions - Nokogiri >= 1.18.9 ## Mitigation Upgrade to Nokogiri v1.18.9 or later. 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.
