The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:4526 advisory.

    GLib provides the core application building blocks for libraries and applications written in C. It     provides the core object system used in GNOME, the main loop implementation, and a large set of utility     functions for strings and common data structures.

    The following packages have been upgraded to a later upstream version: mingw-glib2 (2.66.7). (BZ#1935248,     BZ#1939111)

    Security Fix(es):

    * glib: integer overflow in g_bytes_new function on 64-bit platforms due to an implicit cast from 64 bits     to 32 bits (CVE-2021-27219)

    * glib: integer overflow in g_byte_array_new_take function when called with a buffer of 4GB or more on a     64-bit platform (CVE-2021-27218)

    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.

This update for glib2 fixes the following issues :

CVE-2021-27218: g_byte_array_new_take takes a gsize as length but stores in a guint, this patch will refuse if the length is larger than guint. (bsc#1182328)

CVE-2021-27219: g_memdup takes a guint as parameter and sometimes leads into an integer overflow, so add a g_memdup2 function which uses gsize to replace it. (bsc#1182362)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
