Ruby/nokogiri/1.13.3

Nokogiri (鋸) makes it easy and painless to work with XML and HTML from Ruby. It provides a sensible, easy-to-understand API for reading, writing, modifying, and querying documents. It is fast and standards-compliant by relying on native parsers like libxml2, libgumbo, or xerces.

Summary

Nokogiri v1.13.9 upgrades the packaged version of its dependency libxml2 to v2.10.3 from v2.9.14.

libxml2 v2.10.3 addresses the following known vulnerabilities:

Please note that this advisory only applies to the CRuby implementation of Nokogiri < 1.13.9, 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.

Mitigation

Upgrade to Nokogiri >= 1.13.9.

Users who are unable to upgrade Nokogiri may also choose a more complicated mitigation: compile and link Nokogiri against external libraries libxml2 >= 2.10.3 which will also address these same issues.

Impact

libxml2 CVE-2022-2309

  • CVSS3 score: Under evaluation
  • Type: Denial of service
  • Description: NULL Pointer Dereference allows attackers to cause a denial of service (or application crash). This only applies when lxml is used together with libxml2 2.9.10 through 2.9.14. libxml2 2.9.9 and earlier are not affected. It allows triggering crashes through forged input data, given a vulnerable code sequence in the application. The vulnerability is caused by the iterwalk function (also used by the canonicalize function). Such code shouldn't be in wide-spread use, given that parsing + iterwalk would usually be replaced with the more efficient iterparse function. However, an XML converter that serialises to C14N would also be vulnerable, for example, and there are legitimate use cases for this code sequence. If untrusted input is received (also remotely) and processed via iterwalk function, a crash can be triggered.

Nokogiri maintainers investigated at #2620 and determined this CVE does not affect Nokogiri users.

libxml2 CVE-2022-40304

  • CVSS3 score: Unspecified upstream
  • Type: Data corruption, denial of service
  • Description: When an entity reference cycle is detected, the entity content is cleared by setting its first byte to zero. But the entity content might be allocated from a dict. In this case, the dict entry becomes corrupted leading to all kinds of logic errors, including memory errors like double-frees.

Integer Overflow or Wraparound in libxml2 affects Nokogiri

Published date: 2022-05-18T20:06:48Z
Links:

Summary

Nokogiri v1.13.5 upgrades the packaged version of its dependency libxml2 from v2.9.13 to v2.9.14.

libxml2 v2.9.14 addresses CVE-2022-29824. This version also includes several security-related bug fixes for which CVEs were not created, including a potential double-free, potential memory leaks, and integer-overflow.

Please note that this advisory only applies to the CRuby implementation of Nokogiri < 1.13.5, 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 and libxslt release announcements.

Mitigation

Upgrade to Nokogiri >= 1.13.5.

Users who are unable to upgrade Nokogiri may also choose a more complicated mitigation: compile and link Nokogiri against external libraries libxml2 >= 2.9.14 which will also address these same issues.

Impact

libxml2 CVE-2022-29824

  • CVSS3 score:
  • Type: Denial of service, information disclosure
  • Description: In libxml2 before 2.9.14, several buffer handling functions in buf.c (xmlBuf) and tree.c (xmlBuffer) don't check for integer overflows. This can result in out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software using libxml2's buffer functions, for example libxslt through 1.1.35, is affected as well.
  • Fixed: https://gitlab.gnome.org/GNOME/libxml2/-/commit/2554a24

All versions of libml2 prior to v2.9.14 are affected.

Applications parsing or serializing multi-gigabyte documents (in excess of INT_MAX bytes) may be vulnerable to an integer overflow bug in buffer handling that could lead to exposure of confidential data, modification of unrelated data, or a segmentation fault resulting in a denial-of-service.

Use-after-free in libxml2 via Nokogiri::XML::Reader

Published date: 2024-03-18T20:38:40Z
Links:

Summary

Nokogiri upgrades its dependency libxml2 as follows: - v1.15.6 upgrades libxml2 to 2.11.7 from 2.11.6 - v1.16.2 upgrades libxml2 to 2.12.5 from 2.12.4

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 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/604 - patched by https://gitlab.gnome.org/GNOME/libxml2/-/commit/92721970

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.

Severity

The Nokogiri maintainers have evaluated this as Moderate.

Impact

From the CVE description, this issue applies to the xmlTextReader module (which underlies Nokogiri::XML::Reader):

When using the XML Reader interface with DTD validation and XInclude expansion enabled, processing crafted XML documents can lead to an xmlValidatePopElement use-after-free.

Mitigation

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.

Summary

Nokogiri < v1.13.6 does not type-check all inputs into the XML and HTML4 SAX parsers. For CRuby users, this may allow specially crafted untrusted inputs to cause illegal memory access errors (segfault) or reads from unrelated memory.

Severity

The Nokogiri maintainers have evaluated this as High 8.2 (CVSS3.1).

Mitigation

CRuby users should upgrade to Nokogiri >= 1.13.6.

JRuby users are not affected.

Workarounds

To avoid this vulnerability in affected applications, ensure the untrusted input is a String by calling #to_s or equivalent.

Summary

Nokogiri < v1.13.6 does not type-check all inputs into the XML and HTML4 SAX parsers. For CRuby users, this may allow specially crafted untrusted inputs to cause illegal memory access errors (segfault) or reads from unrelated memory.

Severity

The Nokogiri maintainers have evaluated this as High 8.2 (CVSS3.1).

Mitigation

CRuby users should upgrade to Nokogiri >= 1.13.6.

JRuby users are not affected.

Nokogiri updates packaged libxml2 to v2.13.8 to resolve CVE-2025-32414 and CVE-2025-32415

Published date: 2025-04-21
Links:

Summary

Nokogiri v1.18.8 upgrades its dependency libxml2 to v2.13.8.

libxml2 v2.13.8 addresses:

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.

Update packaged libxml2 to v2.10.4 to resolve multiple CVEs

Published date: 2023-04-11
Links:

Summary

Nokogiri v1.14.3 upgrades the packaged version of its dependency libxml2 to v2.10.4 from v2.10.3.

libxml2 v2.10.4 addresses the following known vulnerabilities:

  • CVE-2023-29469: Hashing of empty dict strings isn't deterministic
  • CVE-2023-28484: Fix null deref in xmlSchemaFixupComplexType
  • Schemas: Fix null-pointer-deref in xmlSchemaCheckCOSSTDerivedOK

Please note that this advisory only applies to the CRuby implementation of Nokogiri < 1.14.3, 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.

Mitigation

Upgrade to Nokogiri >= 1.14.3.

Users who are unable to upgrade Nokogiri may also choose a more complicated mitigation: compile and link Nokogiri against external libraries libxml2 >= 2.10.4 which will also address these same issues.

Impact

No public information has yet been published about the security-related issues other than the upstream commits. Examination of those changesets indicate that the more serious issues relate to libxml2 dereferencing NULL pointers and potentially segfaulting while parsing untrusted inputs.

The commits can be examined at:

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.

Use-after-free in libxml2 via Nokogiri::XML::Reader

Published date: 2024-02-04
Links:

Summary

Nokogiri upgrades its dependency libxml2 as follows: - v1.15.6 upgrades libxml2 to 2.11.7 from 2.11.6 - v1.16.2 upgrades libxml2 to 2.12.5 from 2.12.4

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 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/604 - patched by https://gitlab.gnome.org/GNOME/libxml2/-/commit/92721970

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.

Severity

The Nokogiri maintainers have evaluated this as Moderate.

Impact

From the CVE description, this issue applies to the xmlTextReader module (which underlies Nokogiri::XML::Reader):

When using the XML Reader interface with DTD validation and XInclude expansion enabled, processing crafted XML documents can lead to an xmlValidatePopElement use-after-free.

Mitigation

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.
