 Mandriva Linux Security Advisory                         MDVSA-2012:168
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : hostapd
 Date    : October 22, 2012
 Affected: 2011.
 _______________________________________________________________________

 Problem Description:

 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.
