  script_tag(name:"insight", value:"This update for wpa_supplicant provides the following fixes:

  This security issue was fixed:

  - 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).

  This update was imported from the SUSE:SLE-15:Update update project.
