Vulnerability identifier: #VU29457
Vulnerability risk: Low
Exploitation vector: Network
Exploit availability: No
The vulnerability allows a remote attacker to disable installed Add-Ons.
The vulnerability exists due to Add-On updates do not respect the same certificate trust rules as software updates. 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 This could have caused add-ons to become out-of-date silently without notification to the user.
Install updates from vendor's website.
