Synopsis

The remote Red Hat host is missing one or more security updates for raptor2.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1842 advisory.

Raptor is the RDF Parser Toolkit for Redland that provides a set of standalone RDF parsers, generating triples from RDF/XML or N-Triples.

Security Fix(es):

* raptor: heap-based buffer overflows due to an error in calculating the maximum nspace declarations for the XML writer (CVE-2017-18926)

* raptor2: malformed input file can lead to a segfault due to an out of bounds array access in raptor_xml_writer_start_element_common (CVE-2020-25713)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
