Summary
Heap-based buffer overflow in nokogiri
Details

Heap-based buffer overflow in the xmlGROW function in parser.c in libxml2 before 2.9.3. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to use an excessive amount of CPU, leak potentially sensitive information, or crash the application.
