18 November 2021
Several security issues were fixed in Thunderbird.
Releases
Packages
- thunderbird - Mozilla Open Source mail and newsgroup client
Details
Multiple security issues were discovered in Thunderbird. If a user were
tricked into opening a specially crafted website in a browsing context, an
attacker could potentially exploit these to cause a denial of service,
bypass security restrictions, spoof the UI, confuse the user, conduct
phishing attacks, or execute arbitrary code.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 21.10
After a standard system update you need to restart Thunderbird to make
all the necessary changes.
