high Nessus Plugin ID 157608

Synopsis

The remote AlmaLinux host is missing one or more security updates.

Description

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2021:1842 advisory.

 - 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). (CVE-2017-18926)

 - A 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 this issue but has instead relied only on the application's self-reported version number.

Solution
