Debian Security Advisory DSA-1911-1                  security@xxxxxxxxxx

- ------------------------------------------------------------------------

Package        : pygresql
Vulnerability  : missing escape function
Problem type   : remote
Debian-specific: no
CVE Id         : CVE-2009-2940


It was discovered that pygresql, a PostgreSQL module for Python, was
missing a function to call PQescapeStringConn(). This is needed, because
PQescapeStringConn() honours the charset of the connection and prevents
insufficient escaping, when certain multibyte character encodings are
used. The new function is called pg_escape_string(), which takes the
database connection as a first argument. The old function
escape_string() has been preserved as well for backwards compatibility.

Developers using these bindings are encouraged to adjust their code to
use the new function.


For the stable distribution (lenny), this problem has been fixed in
version 1:3.8.1-3+lenny1.

For the oldstable distribution (etch), this problem has been fixed in
version 1:3.8.1-1etch2.

For the testing distribution (squeeze) and the unstable distribution
(sid), this problem has been fixed in version 1:4.0-1.


We recommend that you upgrade your pygresql packages.


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.
