Overview

libxmljs is a libxml bindings for v8 javascript engine

Affected versions of this package are vulnerable to Out-of-Bounds. The xmlParseElementDecl function in parser.c in libxml2 before 2.9.4 allows context-dependent attackers to cause a denial of service (heap-based buffer underread and application crash) via a crafted file, involving xmlParseName.
