The remote host is missing an update to hostapd announced via advisory DSA 1065-1. 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. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201065-1
