Fedora 30: expat FEDORA-2019-18868e1715
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.
This update includes a fix for a security vulnerability, CVE_2018-20843: > Fix
extraction of namespace prefixes from XML names; XML names with multiple colons
could end up in the wrong namespace, and take a high amount of RAM and CPU
resources while processing, opening the door to use for denial-of-service
attacks For more information on the changes in 2.2.7, see the upstream release
