Arch Linux

Issue
=====
Two vulnerabilities have been reported in PostgreSQL, which
potentially can be exploited by malicious people to conduct SQL
injection attacks.

The vulnerabilities are caused due to the differences in the way
PostgreSQL server and non-encoding aware applications interpret SQL
query strings that contain certain multi-byte characters. A
non-encoding aware application may insert escape characters into a
malicious query string (e.g. to escape single-quote or backslash
characters), without realizing that the escape characters will be
interpreted as part of a multi-byte character sequence by the server.
This can be exploited to conduct SQL injection attacks by injecting
certain multi-byte characters into the query string.

Successful exploitation allows bypassing of SQL injection escaping
code that are implemented in non-encoding aware applications.

Solution
========
Postgres 8.1.4 has been released to patch this vulnerability. It can be downloaded at:
