Fedora Update Notification
FEDORA-2019-27e7b92407
2019-04-22 05:09:02.624501
--------------------------------------------------------------------------------
Name : libxmlb
Product : Fedora 29
Version : 0.1.8
Release : 2.fc29
URL :
https://github.com/hughsie/libxmlb
Summary : Library for querying compressed XML metadata
Description :
XML is slow to parse and strings inside the document cannot be memory mapped as
they do not have a trailing NUL char. The libxmlb library takes XML source, and
converts it to a structured binary representation with a deduplicated string
table -- where the strings have the NULs included.
This allows an application to mmap the binary XML file, do an XPath query and
return some strings without actually parsing the entire document. This is all
done using (almost) zero allocations and no actual copying of the binary data.

Update Information:
This update fixes a [
bug](https://github.com/mesonbuild/meson/issues/5268) in
the Meson build system which caused binaries and libraries to incorrectly be
marking as requiring an executable stack. This makes them more vulnerable to
security issues, and also can result in errors caused by SELinux denials. This
update also provides rebuilds of all the packages that were built with the buggy
Meson, excepting packages for updates were already pending (in those cases,
those updates have been edited instead).
--------------------------------------------------------------------------------
This update can be installed with the "dnf" update program. Use
su -c 'dnf upgrade --advisory FEDORA-2019-27e7b92407' at the command
line. For more information, refer to the dnf documentation available at
http://dnf.readthedocs.io/en/latest/command_ref.html#upgrade-command-label
All packages are signed with the Fedora Project GPG key. More details on the
GPG keys used by the Fedora Project can be found at
