CVSS: 7.1EPSS: 0%CPEs: 6EXPL: 1CVE-2017-18926 – raptor: heap-based buffer overflows due to an error in calculating the maximum nspace declarations for the XML writer
https://notcve.org/view.php?id=CVE-2017-18926
raptor_xml_writer_start_element_common in raptor_xml_writer.c in Raptor RDF Syntax Library 2.0.15 miscalculates the maximum nspace declarations for the XML writer, leading to heap-based buffer overflows (sometimes seen in raptor_qname_format_as_xml). La función raptor_xml_writer_start_element_common en el archivo raptor_xml_writer.c en Raptor RDF Syntax Library versión 2.0.15, calcula inapropiadamente las declaraciones máximas nspace para el escritor XML, conllevando a desbordamientos del búfer en la región heap de la memoria (algunas veces se ve en la función raptor_qname_format_as_xml) • http://www.openwall.com/lists/oss-security/2020/11/13/1 http://www.openwall.com/lists/oss-security/2020/11/13/2 http://www.openwall.com/lists/oss-security/2020/11/14/2 http://www.openwall.com/lists/oss-security/2020/11/16/2 http://www.openwall.com/lists/oss-security/2020/11/16/3 https://github.com/LibreOffice/core/blob/master/external/redland/raptor/0001-Calcualte-max-nspace-declarations-correctly-for-XML-.patch.1 https://lists.debian.org/debian-lts-announce& • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
