-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------- Debian Security Advisory DSA-2557-1 security@xxxxxxxxxx http://www.debian.org/security/ Nico Golde October 08, 2012 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : hostapd Vulnerability : buffer overflow Problem type : remote Debian-specific: no CVE ID : CVE-2012-4445 Timo Warns discovered that the internal authentication server of hostapd, a user space IEEE 802.11 AP and IEEE 802.1X/WPA/WPA2/EAP Authenticator, is vulnerable to a buffer overflow when processing fragmented EAP-TLS messages. As a result, an internal overflow checking routine terminates the process. An attacker can abuse this flaw to conduct denial of service attacks via crafted EAP-TLS messages prior to any authentication. For the stable distribution (squeeze), this problem has been fixed in version 0.6.10-2+squeeze1. For the testing (wheezy) and unstable (sid) distributions, this problem will be fixed soon. We recommend that you upgrade your hostapd packages.
