Description Agostino Sarubbo gentoo-dev 2019-03-25 11:34:24 UTC
From ${URL} :

rbash in Bash before 4.4-beta2 did not prevent the shell user from modifying BASH_CMDS, thus allowing the user to execute any command with the 
permissions of the shell.


Upstream commit:

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

We already have app-shells/bash-4.4_p23-r1 stable. So no action required from base-system here.
