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).");
