CVE-2015-8317

Published: 23 November 2015

The xmlParseXMLDecl function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to obtain sensitive information via an (1) unterminated encoding value or (2) incomplete XML declaration in XML data, which triggers an out-of-bounds heap read.
