Subject: [PATCH] WNM: Ignore Key Data in WNM Sleep Mode Response frame if no
|
||||
PMF in use
|

|
||||
WNM Sleep Mode Response frame is used to update GTK/IGTK only if PMF is

enabled. Verify that PMF is in use before using this field on station
|

side to avoid accepting unauthenticated key updates. (CVE-2015-5310)

Subject: [PATCH] EAP-pwd server: Fix last fragment length validation
|

|
||||
All but the last fragment had their length checked against the remaining

room in the reassembly buffer. This allowed a suitably constructed last

fragment frame to try to add extra data that would go beyond the buffer.
|

The length validation code in wpabuf_put_data() prevents an actual

buffer write overflow from occurring, but this results in process

termination. (CVE-2015-5314)

Subject: [PATCH 1/5] WPS: Reject a Credential with invalid passphrase
|
||||
|
||||
WPA/WPA2-Personal passphrase is not allowed to include control
|
||||
characters. Reject a Credential received from a WPS Registrar both as
|
||||
STA (Credential) and AP (AP Settings) if the credential is for WPAPSK or
|
||||
WPA2PSK authentication type and includes an invalid passphrase.
|
||||
|
||||
This fixes an issue where hostapd or wpa_supplicant could have updated
|
||||
the configuration file PSK/passphrase parameter with arbitrary data from
|
||||
an external device (Registrar) that may not be fully trusted. Should
|
||||
such data include a newline character, the resulting configuration file
|
||||
could become invalid and fail to be parsed.

Subject: [PATCH 2/5] Reject psk parameter set with invalid passphrase
|
||||
character
|
||||
|
||||
WPA/WPA2-Personal passphrase is not allowed to include control
|
||||
characters. Reject a passphrase configuration attempt if that passphrase
|
||||
includes an invalid passphrase.
|
||||
|
||||
This fixes an issue where wpa_supplicant could have updated the
|
||||
configuration file psk 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 passphrase value before passing it to
|
||||
wpa_supplicant.
|
||||
|
||||
This could allow such an untrusted user to inject up to 63 characters of
|
||||
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.

Subject: [PATCH 3/5] Remove newlines from wpa_supplicant config network
|
||||
output
|
||||
|
||||
Spurious newlines output while writing the config file can corrupt the
|
||||
wpa_supplicant configuration. Avoid writing these for the network block
|
||||
parameters. This is a generic filter that cover cases that may not have
|
||||
been explicitly addressed with a more specific commit to avoid control
|
||||
characters in the psk parameter.

Subject: [PATCH 4/5] Reject SET_CRED commands with newline characters in the
|
||||
string values
|
||||
|
||||
Most of the cred block 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 cred 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 credential value 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.
