Test ID:1.3.6.1.4.1.25623.1.0.876041
Category:Fedora Local Security Checks
Title:Fedora Update for libxmlb FEDORA-2019-27e7b92407
Summary:The remote host is missing an update for the 'libxmlb'; package(s) announced via the FEDORA-2019-27e7b92407 advisory.
Description:Summary:
The remote host is missing an update for the 'libxmlb'
package(s) announced via the FEDORA-2019-27e7b92407 advisory.

Vulnerability Insight:
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.

Affected Software/OS:
'libxmlb' package(s) on Fedora 29.

Solution:
Please install the updated package(s).

CVSS Score:
5.0
