Details
Matheus Tavares discovered that Git incorrectly handled delay-capable
clean/smudge filters when being used on case-insensitive filesystems. A
remote attacker could possibly use this issue to execute arbitrary code.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.10
Ubuntu 20.04
Ubuntu 18.04
Ubuntu 16.04
In general, a standard system update will make all the necessary changes.
