An upgrade for wpa_supplicant on openSUSE addresses a cryptographic vulnerability and enhances the security protocols used for authentication.
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:

- 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:

- 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).
