______________________________________________________________________________

   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).
