========================================================================== Ubuntu Security Notice USN-4761-1 March 09, 2021
git vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.10 - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS
Summary:
Git could be made to run programs if it received specially crafted network traffic.
Software Description: - git: fast, scalable, distributed revision control system
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: git 1:2.27.0-1ubuntu1.1
Ubuntu 20.04 LTS: git 1:2.25.1-1ubuntu3.1
Ubuntu 18.04 LTS: git 1:2.17.1-1ubuntu0.8
Ubuntu 16.04 LTS: git 1:2.7.4-0ubuntu1.10
In general, a standard system update will make all the necessary changes.
