Subject: [PATCH 5/5] Reject SET commands with newline characters in the
|
|
string values
|
|
|
|
Many of the global configuration parameters are written as strings
|
|
without filtering and if there is an embedded newline character in the
|
|
value, unexpected configuration file data might be written.
|
|
|
|
This fixes an issue where wpa_supplicant could have updated the
|
|
configuration file global parameter with arbitrary data from the control
|
|
interface or D-Bus interface. While those interfaces are supposed to be
|
|
accessible only for trusted users/applications, it may be possible that
|
|
an untrusted user has access to a management software component that
|
|
does not validate the value of a parameter before passing it to
|
|
wpa_supplicant.
|
|
|
|
This could allow such an untrusted user to inject almost arbitrary data
|
|
into the configuration file. Such configuration file could result in
|
|
wpa_supplicant trying to load a library (e.g., opensc_engine_path,
|
|
pkcs11_engine_path, pkcs11_module_path, load_dynamic_eap) from user
|
|
controlled location when starting again. This would allow code from that
|
|
library to be executed under the wpa_supplicant process privileges.
