pipewire was updated to version 0.3.6 (bsc#1171433, jsc#ECO-2308) :

  - Extensive memory leak fixing and stress testing was     done. A big leak in screen sharing with DMA-BUF was     fixed.

  - Compile fixes

  - Stability improvements in jack and pulseaudio layers.

  - Added the old portal module to make the Camera portal     work again. This will be moved to the session manager in     future versions.

  - Improvements to the GStreamer source and sink shutdown.

  - Fix compatibility with v2 clients again when negotiating     buffers.

The version of Firefox installed on the remote Windows host is prior to 79.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-30 advisory.

  - Mozilla developers and community members Kevin Brosnan, Alexandru Michis, Natalia Csoregi, Jason Kratzer,     Christian Holler, Simon Giesecke, Luke Wagner reported memory safety bugs present in Firefox 78. Some of     these bugs showed evidence of memory corruption and we presume that with enough effort some of these could     have been exploited to run arbitrary code. (CVE-2020-15659)

  - Crafted media files could lead to a race in texture caches, resulting in a use-after-free, memory     corruption, and a potentially exploitable crash. (CVE-2020-6463)

  - By observing the stack trace for JavaScript errors in web workers, it was possible to leak the result of a     cross-origin redirect. This applied only to content that can be parsed as script. (CVE-2020-15652)

  - WebRTC used the memory address of a class instance as a connection identifier. Unfortunately, this value     is often transmitted to the peer, which allows bypassing ASLR. (CVE-2020-6514)

  - Mozilla Developer Rob Wu discovered that a redirected HTTP request which is observed or modified through a     web extension could bypass existing CORS checks, leading to potential disclosure of cross-origin     information. (CVE-2020-15655)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 78.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-32 advisory.

  - Mozilla developers and community members Natalia Csoregi, Simon Giesecke, Jason Kratzer, Christian Holler,     and Luke Wagner reported memory safety bugs present in Firefox 78 and Firefox ESR 78.0. Some of these bugs     showed evidence of memory corruption and we presume that with enough effort some of these could have been     exploited to run arbitrary code. (CVE-2020-15659)

The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 78.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-33 advisory.
