Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 36 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-efe0594c2b advisory.

 * Fix large memory allocation when uploading content.
 * Fix scrolling after a history navigation with PSON enabled.
 * Always update the active uri of WebKitFrame.
 * Fix several crashes and rendering issues.
 * Security fixes: CVE-2023-23529


 ----

 * Improve GStreamer multimedia playback across the board with improved codec selection logic, better handling of latency, and improving frame discard to avoid audio/video desynchronization, among other fixes.
 * Disable HLS media playback by default, which makes web sites use MSE instead. If needed WEBKIT_GST_ENABLE_HLS_SUPPORT=1 can be set in the environment to enable it back.
 * Disable threaded rendering in GTK4 builds by default, as it was causing crashes.
 * Fix MediaSession API not showing artwork images.
 * Fix MediaSession MPRIS usage when running inside a Flatpak sandbox.
 * Fix input element controls to correctly scale when applying a zoom factor different than the default.
 * Fix leakage of Web processes in certain situations.
 * Fix several crashes and rendering issues.
 * Security fixes: CVE-2023-23517, CVE-2023-23518, CVE-2022-42826, and many additional security issues
