Description TEJ RATHI 2023-04-21 05:59:20 UTC 
The WebKitGTK flaw CVE-2023-28205 (bug 2185724) was addressed in Red Hat Enterprise Linux 8 via erratum RHSA-2023:1919 and in Red Hat Enterprise Linux 9 via erratum RHSA-2023:1918, released on Apr 20, 2023:

https://access.redhat.com/errata/RHSA-2023:1919
https://access.redhat.com/errata/RHSA-2023:1918

However, the fix for this issue was not included in the WebKitGTK updates released as part of Red Hat Enterprise Linux 8.8 GA erratum (RHSA-2023:2834) and Red Hat Enterprise Linux 9.2 GA erratum (RHSA-2023:2256), causing a security regression of previously released fix. A new CVE-ID CVE-2023-2203 was assigned for this security regression.

Note that this issue and CVE-ID is specific to the WebKitGTK packages as shipped with Red Hat Enterprise Linux and is not applicable to any upstream WebKitGTK version or WebKitGTK packages of any other vendor that are not directly based on Red Hat Enterprise Linux packages.
