Overview

nokogiri is an HTML, XML, SAX, and Reader parser, with the ability to search documents via XPath or CSS3 selectors. Affected versions of this Gem are vulnerable to both Memory Exhaustion and Sensitive Information Exposure.

Details

Heap-based buffer overflow in the xmlGROW function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to obtain sensitive process memory information via unspecified vectors.

libxml2 could be made to crash if it opened a specially crafted file. It was discovered that libxml2 incorrectly handled certain malformed documents. If a user or automated system were tricked into opening a specially crafted document, an attacker could possibly cause libxml2 to crash, resulting in a denial of service.
