Synopsis

The Rocky Linux host is missing one or more security updates.

Description

The Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-2021_1842 advisory.

* 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)

Tenable has extracted the preceding description block directly from the CIQ security advisory.

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

Solution

Update the affected packages based on the guidance in CIQ advisory crlsa-2021_1842.
