Pale Moon has been updated to version 31.4.0.  This is a major development and security update adding JPEG-XL image support and more.

 

Changes/Fixes:

  • Added support for the JPEG-XL image format.
  • Implemented regular expressions lookaround/lookbehind.
  • Aligned CORS header parsing with the updated spec. See implementation notes.
  • We no longer fire keypress events for non-printable keys. See implementation notes.
  • Added support for MacOS 13 "Ventura" in the platform, primarily benefitting White Star.
  • Fixed potentially problematic thread locking code on *nix platforms.
  • Fixed some small issues in the display and operation of the Web Developer tools.
  • Removed unused but performance-impacting panning and tab animation measuring code. (telemetry leftovers)
  • Improved code for SunOS builds.
  • Updated Internationalization data for time zones.
  • Fixed a buffer overflow for Mac builds.
  • Security issues addressed: CVE-2022-45411 and potential issues without a CVE number.
  • UXP Mozilla security patch summary: 2 fixed, 1 DiD, 1 deferred, 25 not applicable.

Implementation Notes:

  • CORS support has been updated to the current spec. Most importantly, Pale Moon now accepts wildcard entries ("*") for the CORS statements Access-Control-Expose-Headers, Access-Control-Allow-Headers and Access-Control-Allow-Method. Note that wildcards are ignored (according to the spec) when credentials are passed.
  • Pale Moon will no longer fire the keypress events in content when the key pressed is a non-printable key. This is in response to issues where webmasters would use rudimentary and naïve input-restricting scripts in onkeypress handlers that would not take into account editing keys or navigation keys, causing issues for users trying to enter data into forms (and e.g. finding they could no longer use backspace, cursor keys or tab). This aligns our behavior with other browsers for web compatibility, although it should be considered a website error expecting not all keypresses to be intercepted in keypress events.


*DiD This means that a fix is "Defense-in-Depth": It is a fix that does not apply to a (potentially) actively exploitable vulnerability in Pale Moon, but prevents future vulnerabilities caused by the same code, e.g. when surrounding code changes, exposing the problem, or when new attack vectors are discovered.

**Rejected security patches: This means that patches were theoretically applicable to our code but considered undesirable, which could be due to unwanted changes in behavior, known regressions caused by the patches, or unnecessary risks for stability, security or privacy.

Pale Moon includes both 32- and 64-bit versions for Windows: Pale Moon for Windows downloads.

We are aware of our JPEG-XL decoder in 31.4.0 doing something funky with the colors. We're working on a fix for this!
