An update that solves one vulnerability and has 5 fixes is
now available.

Description:

This update for wpa_supplicant provides the following fixes:

This security issues was fixe:

- CVE-2018-14526: Under certain conditions, the integrity of EAPOL-Key
messages was not checked, leading to a decryption oracle. An attacker
within range of the Access Point and client could have abused the
vulnerability to recover sensitive information (bsc#1104205)

These non-security issues were fixed:

- Fix reading private key passwords from the configuration file.
(bsc#1099835)
- Enable PWD as EAP method. This allows for password-based authentication,
which is easier to setup than most of the other methods, and is used by
the Eduroam network. (bsc#1109209)
- compile eapol_test binary to allow testing via radius proxy and server
(note: this does not match CONFIG_EAPOL_TEST which sets -Werror and
activates an assert call inside the code of wpa_supplicant)
(bsc#1111873), (fate#326725)
- Enabled timestamps in log file when being invoked by systemd service
file (bsc#1080798).
- Fixes the default file permissions of the debug log file to more sane
values, i.e. it is no longer world-readable (bsc#1098854).
- Open the debug log file with O_CLOEXEC, which will prevent file
descriptor leaking to child processes (bsc#1098854).
