Описание
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.
A flaw was found in Nokogiri, specifically in its bundled libxml2 library when processing XML schemas. An attacker can exploit this by providing a specially crafted XML schema, leading to a NULL pointer dereference. This can cause the application to crash, resulting in a denial of service.
Отчет
This is a Moderate denial of service flaw in Nokogiri's bundled libxml2, affecting CRuby implementations that process XML schemas using packaged libraries. A remote attacker could provide a specially crafted XML schema, leading to a NULL pointer dereference and causing the application to crash, thereby impacting service availability. The impact is limited to applications that directly process untrusted XML schemas with the vulnerable Nokogiri configuration.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
