Git could be made to expose sensitive information.

Releases

Packages

  • git - fast, scalable, distributed revision control system

Details

Carlo Arenas discovered that Git incorrectly handled certain URLs
containing newlines, empty hosts, or lacking a scheme. A remote attacker
could possibly use this issue to trick Git into returning credential
information for a wrong host.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 19.10
Ubuntu 18.04
Ubuntu 16.04

In general, a standard system update will make all the necessary changes.
