rPath Security Advisory: 2006-0080-1

Description

PostgreSQL contains a flaw that may allow a malicious user to bypass security restrictions and execute arbitrary SQL commands. The issue is triggered due to an error when escaping ASCII single quote "'" characters (by turning them into "\'") and operating in multibyte encodings (e.g. SJIS, BIG5, GBK, GB18030, or UHC) that allow using the "0x5c" ASCII code (backslash) as the trailing byte of a multibyte character. It is possible that the flaw may allow SQL injection attacks resulting in a loss of confidentiality and integrity.
