EulerOS Virtualization 2.9.1 : glib2 (EulerOS-SA-2023-2956)

high Nessus Plugin ID 188697

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the glib2 package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - Rejected reason: Rejected by upstream. (CVE-2023-24593, CVE-2023-25180)

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

Solution

Update the affected glib2 packages.
