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.
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
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.
