Tails 5.3.1 is out

2022-08-02

This release is an emergency release to fix a security vulnerability in 
the Linux kernel.

Changes and updates

Update the Linux kernel to 5.10.127-2, which fixes CVE-2022-34918, a 
vulnerability that allows applications in Tails to gain administration 
privileges.

For example, if an attacker was able to exploit other unknown security 
vulnerabilities in Tor Browser, they might then use CVE-2022-34918 to 
take full control of your Tails and deanonymize you.

This attack is very unlikely, but could be performed by a strong 
attacker, such as a government or a hacking firm. We are not aware of 
this attack being used in the wild.

Update Thunderbird to 91.12.0.
