An update that solves one vulnerability and has one errata is now available.
Description:
This update for wpa_supplicant fixes the following issues:
This security issue was fixed:
o 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).
This non-security issue was fixed:
o Enabled 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).
