- update to 5.8.1 (bsc#1196435, CVE-2021-45444):
* CVE-2021-45444: Some prompt expansion sequences, such as %F, support
'arguments' which are themselves expanded in case they contain colour
values, etc. This additional expansion would trigger PROMPT_SUBST
evaluation, if enabled. This could be abused to execute code the user
didn't expect. e.g., given a certain prompt configuration, an attacker
could trick a user into executing arbitrary code by having them check
out a Git branch with a specially crafted name.
This is fixed in the shell itself by no longer performing PROMPT_SUBST
evaluation on these prompt-expansion arguments.
Users who are concerned about an exploit but unable to update their
binaries may apply the partial work-around described in the file
Etc/CVE-2021-45444-VCS_Info-workaround.patch included with the shell
source. [ Reported by RyotaK <security@ryotak.me>. Additional thanks to
