Package : hostapd
Vulnerability : missing input sanitising
Problem-Type : remote
Debian-specific: no
CVE ID : CVE-2006-2213
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.
