Synopsis

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

Description

The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2023:1697135256 advisory.

- A flaw was found in GLib. GVariant deserialization fails to validate that the input conforms to the expected format, leading to denial of service. (CVE-2023-29499)

- A flaw was found in GLib. GVariant deserialization is vulnerable to a slowdown issue where a crafted GVariant can cause excessive processing, leading to denial of service. (CVE-2023-32611)

- A flaw was found in glib, where the gvariant deserialization code is vulnerable to a denial of service introduced by additional input validation added to resolve CVE-2023-29499. The offset table validation may be very slow. This bug does not affect any released version of glib but does affect glib distributors who followed the guidance of glib developers to backport the initial fix for CVE-2023-29499. (CVE-2023-32636)

- A flaw was found in GLib. The GVariant deserialization code is vulnerable to a heap buffer overflow introduced by the fix for CVE-2023-32665. This bug does not affect any released version of GLib, but does affect GLib distributors who followed the guidance of GLib developers to backport the initial fix for CVE-2023-32665. (CVE-2023-32643)

- A flaw was found in GLib. GVariant deserialization is vulnerable to an exponential blowup issue where a crafted GVariant can cause excessive processing, leading to denial of service. (CVE-2023-32665)

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 TuxCare advisory CENTOS7:CLSA-2023:1697135256.
