Issue Overview:

parser.c in libxml2 before 2.9.0, as used in Google Chrome before 28.0.1500.71 and other products, allows remote attackers to cause a denial of service (out-of-bounds read) via a document that ends abruptly, related to the lack of certain checks for the XML_PARSER_EOF state.

Affected Packages:

libxml2

Issue Correction:
Run yum update libxml2 to update your system.
