Package        : ekg
Vulnerability  : integer overflows
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2005-1852

Marcin Slusarz discovered two integer overflow vulnerabilities in
libgadu, a library provided and used by ekg, a console Gadu Gadu
client, an instant messaging program, that could lead to the execution
of arbitrary code.

The library is also used by other packages such as kopete, which
should be restarted to take effect of this update.

The old stable distribution (woody) does not contain an ekg package.

For the stable distribution (sarge) these problems have been fixed in
version 1.5+20050411-5.

For the unstable distribution (sid) these problems have been fixed in
version 1.5+20050718+1.6rc3-1.

We recommend that you upgrade your ekg 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

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

Vulnerability  : missing input validation
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2005-2161
Debian Bug     : 317739

A cross-site scripting vulnerability has been detected in phpBB2, a
fully featured and skinneable flat webforum software, that allows
remote attackers to inject arbitrary web script or HTML via nested

The old stable distribution (woody) does not contain phpbb2.

For the stable distribution (sarge) this problem has been fixed in
version 2.0.13-6sarge1.

For the unstable distribution (sid) this problem has been fixed in
version 2.0.13-6sarge1.

We recommend that you upgrade your phpbb2 packages.
