Fedora: 2009-12737 critical: expat buffer over-read issue

fedora
Calendar Grey December 5, 2009
Dist Fedora Esm H88
The Fedora 12 expat library includes a significant security update addressing buffer over-read vulnerabilities found in the handling of XML files.
Two buffer over-read flaws were found in the way Expat handled malformed UTF-8 sequences when processing XML files

Summary

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:

Two buffer over-read flaws were found in the way Expat handled malformed UTF-8 sequences when processing XML files. A specially-crafted XML file could cause applications using Expat to crash while parsing the file. (CVE-2009-3560, CVE-2009-3720)
