Mandriva Linux Security Advisory : hostapd (MDVSA-2012:168)

Medium Nessus Plugin ID 62659


The remote Mandriva Linux host is missing a security update.


Multiple vulnerabilities has been discovered and corrected in hostapd :

hostapd 0.7.3, and possibly other versions before 1.0, uses 0644 permissions for /etc/hostapd/hostapd.conf, which might allow local users to obtain sensitive information such as credentials (CVE-2012-2389).

Heap-based buffer overflow in the eap_server_tls_process_fragment function in eap_server_tls_common.c in the EAP authentication server in hostapd 0.6 through 1.0 allows remote attackers to cause a denial of service (crash or abort) via a small TLS Message Length value in an EAP-TLS message with the More Fragments flag set (CVE-2012-4445).

The updated packages have been patched to correct these issues.


Update the affected hostapd package.
