Advisory: RHBA-2010:0764-1
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2010-10-12

Details

Updated libxml2 packages that fix an erratic behavior of the XPath
implementation.

libxml2 is a library for parsing and manipulating XML files. It includes support
for reading, modifying, and writing XML and HTML files. Libxml2 implements the
XPath specification which is a language for addressing parts of an XML document.

This update fixes the following bug:

* Due to an uninitialized field in one of the private libxml2 XPath data
structures, the XPath evaluation may have return incorrect results. This error
has been fixed, the field is now initialized properly, and XPath evaluation
returns expected results. (BZ#640191)

Users of libxml2 are advised to upgrade to these updated packages, which resolve
this issue.


Solution

Before applying this update, make sure that all previously-released errata
relevant to your system have been applied.
