"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).
