Advisory Release Date: 2014-05-21 10:31 Pacific
Advisory Updated Date: 2014-09-18 00:35 Pacific
It was discovered that libxml2, a library providing support to read, modify and write XML files, incorrectly performs entity substituton in the doctype prolog, even if the application using libxml2 disabled any entity substitution. A remote attacker could provide a specially-crafted XML file that, when processed, would lead to the exhaustion of CPU and memory resources or file descriptors.
Affected Packages:
libxml2
Issue Correction:
Run yum update libxml2 to update your system.
