Debian Bug     : 365897

Matteo Rosi and Leonardo Maccari discovered that hostapd, a wifi network
authenticator daemon, performs insufficient boundary checks on a key length
value, which might be exploited to crash the service.

The old stable distribution (woody) does not contain hostapd packages.

For the stable distribution (sarge) this problem has been fixed in
version 0.3.7-2sarge1.

For the unstable distribution (sid) this problem has been fixed in
version 0.5-1.

We recommend that you upgrade your hostapd package.

Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.

hostapd hostapd 0.3.9

- 漏洞讨论

The hostapd application is affected by a remote denial-of-service vulnerability. This issue is due to the application's failure to properly handle malformed EAPOL-Key packets.

This issue allows remote attackers to crash affected applications, denying further network service to legitimate users.

Version 0.3.7 of hostapd is vulnerable to this issue; previous versions may also be affected.

- 漏洞利用

This issue can be exploited via existing wireless-networking utilities.

- 解决方案

The vendor has released version 0.3.8 to address this issue.

Please see the referenced vendor advisories for more information.
