Summary

Moderate: raptor2 security and bug fix update

Details

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)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
