Description :

Akio Ishida and Yasuo Ohgaki discovered a weakness in the handling of
invalidly-encoded multibyte text data. If a client application
processed untrusted input without respecting its encoding and applied
standard string escaping techniques (such as replacing a single quote
>>'<< with >>\'<< or >>''<<), the PostgreSQL server could interpret the
resulting string in a way that permited a possible hacker to inject arbitrary
SQL commands into the resulting SQL query. The PostgreSQL server has
been modified to reject such invalidly encoded strings now, which
completely fixes the problem for some 'safe' multibyte encodings like

However, there are some less popular and client-only multibyte
encodings (such as SJIS, BIG5, GBK, GB18030, and UHC) which contain
valid multibyte characters that end with the byte 0x5c, which is the
representation of the backslash character >>\<< in ASCII. Many client
libraries and applications use the non-standard, but pop
