Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DSA-2557-1)
Summary:	The remote host is missing an update for the Debian 'hostapd' package(s) announced via the DSA-2557-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'hostapd' package(s) announced via the DSA-2557-1 advisory. Vulnerability Insight: 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 1:0.6.10-2+squeeze1. For the testing (wheezy) and unstable (sid) distributions, this problem will be fixed soon. We recommend that you upgrade your hostapd packages. Affected Software/OS: 'hostapd' package(s) on Debian 6. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:N/A:P
