Originalnachricht |
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)
