Description

When performing add-on updates, certificate chains terminating in non-built-in-roots were rejected (even if they were legitimately added by an administrator.) This could have caused add-ons to become out-of-date silently without notification to the user. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.

Solution(s)

  • alpine-linux-upgrade-firefox-esr
  • alpine-linux-upgrade-firefox
  • alpine-linux-upgrade-mozjs68
  • alpine-linux-upgrade-thunderbird
