CVE-2018-14526

An issue was discovered in rsn_supp/wpa.c in wpa_supplicant 2.0 through 2.6. Under certain conditions, the integrity of EAPOL-Key messages is not checked, leading to a decryption oracle. An attacker within range of the Access Point and client can abuse the vulnerability to recover sensitive information.

These are all security issues fixed in the hostapd-2.9-6.2 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the wpa_supplicant-2.9-13.4 package on the GA media of openSUSE Tumbleweed.

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).

It was discovered that wpa_supplicant and hostapd incorrectly handled certain messages. An attacker could possibly use this to access sensitive information.
