Mandriva Linux Security Advisory 2012-168
Posted Oct 23, 2012
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2012-168 - 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. 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 via a small TLS Message Length value in an EAP-TLS message with the More Fragments flag set. The updated packages have been patched to correct these issues.

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.
