Name        : expat
Product     : Fedora 17
Version     : 2.1.0
Release     : 1.fc17
URL         : http://www.libexpat.org/
Summary     : An XML parser library
Description :
This is expat, the C library for parsing XML, written by James Clark. Expat
is a stream oriented XML parser. This means that you register handlers with
the parser prior to starting the parse. These handlers are called when the
parser discovers the associated structures in the document being parsed. A
start tag is an example of the kind of structures for which you may
register handlers.

Update Information:

This update includes expat 2.1.0, which fixes includes a fix for a security
issue.

A specially-crafted set of keys could trigger hash function collisions, which
degrade dictionary performance by changing hash table operations complexity from
an expected/average O(1) to the worst case O(n).  Reporters were able to find
colliding strings efficiently using meet in the middle attack.  (CVE-2012-0876)
