I'm about to attach a series of patches against Rawhide git that pull in
changes from upstream and RHEL 6 to address:
* XPath hardening fixes from RHEL-6
I could apply these patches as a provenpackager, or I'm willing to become
co-maintainer in Fedora. However, I'd prefer Daniel's feedback first given that
he is both upstream and RHEL maintainer and knows much more than I do.

I'm trying to make a new libxml2 upstream release, it was delayed for various
reasons, including a heavy backlog and some vacations. Once done and pushed
it would fix all those in one go (and more including some schemas validation
fixes which affects a couple of other projects),
sorry for being late !
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.
(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
libxml2-2.7.8-7.fc16 is build for f16
libxml2-2.7.8-8.fc17 is built for f17
f18/rawhide will be rebased as soon as 2.9.0 is out in a few days
libxml2-2.7.8-7.fc16 has been submitted as an update for Fedora 16.
libxml2-2.7.8-8.fc17 has been submitted as an update for Fedora 17.
* should fix your issue,
* was pushed to the Fedora 17 testing repository,
* should be available at your local mirror within two days.
Update it with:
# su -c 'yum update --enablerepo=updates-testing libxml2-2.7.8-8.fc17'
as soon as you are able to.
Please go to the following url:
then log in and leave karma (feedback).
libxml2-2.7.8-9.fc17 has been submitted as an update for Fedora 17.
libxml2-2.7.8-8.fc16 has been submitted as an update for Fedora 16.
libxml2-2.7.8-9.fc17 has been pushed to the Fedora 17 stable repository. If problems still persist, please make note of it in this bug report.
