Fedora 11 Update FEDORA-2009-10987 Critical: Expat Buffer Over-Read

fedora
Calendar Grey November 4, 2009
Dist Fedora Esm H88
Ubuntu 20.04 resolves a critical vulnerability in libjpeg with patch 1.5.3-1ubuntu1, strengthening image processing security.
This update fixes a security vulnerability: A buffer over-read flaw was found in the way Expat handles 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:

This update fixes a security vulnerability: A buffer over-read flaw was found in the way Expat handles 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-2009-3720)
