This CVE ID has been rejected as a duplicate.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade the Nokogiri gem to version 1.14.3 or newer, which bundles libxml2 2.10.4 and eliminates the NULL pointer dereference.
  • If an upgrade cannot be performed immediately, reconfigure or limit XML Schema validation in the application to avoid processing untrusted schemas and thereby prevent the vulnerable code path.
  • Apply application hardening measures such as running the Ruby process under a non‑privileged user and containing it within a sandbox to reduce the impact of a potential segmentation fault.

Description Nokogiri before 1.14.3 (CRuby implementation only, when using the packaged libxml2) bundles libxml2 v2.10.3, which is vulnerable to NULL pointer dereferences in XML Schema processing (xmlSchemaFixupComplexType, CVE-2023-28484, and xmlSchemaCheckCOSSTDerivedOK). An attacker who supplies a crafted/malformed XML schema can cause libxml2 to dereference a NULL pointer and potentially segfault, resulting in a denial of service. Nokogiri 1.14.3 upgrades the packaged libxml2 to v2.10.4 to resolve these issues. This CVE ID has been rejected as a duplicate.
