Logicalware MailManager before 2.0.10 does not remove 0xc8 0x27 (0xc8 followed by a single-quote character) from the data stream to the server, which allows remote attackers to modify data and gain administrative access when PostgreSQL is used, aka "bug #1494281 - Postgres encoding security hole." NOTE: while this issue involves PostgreSQL, it is specific to MailManager's interface to PostgreSQL and is therefore a different vulnerability than CVE-2006-2313 and CVE-2006-2314.

PostgreSQL 8.1.x before 8.1.4, 8.0.x before 8.0.8, 7.4.x before 7.4.13, 7.3.x before 7.3.15, and earlier versions allows context-dependent attackers to bypass SQL injection protection methods in applications that use multibyte encodings that allow the "\" (backslash) byte 0x5c to be the trailing byte of a multibyte character, such as SJIS, BIG5, GBK, GB18030, and UHC, which cannot be handled correctly by a client that does not understand multibyte encodings, aka a second variant of "Encoding-Based SQL Injection." NOTE: it could be argued that this is a class of issue related to interaction errors between the client and PostgreSQL, but a CVE has been assigned since PostgreSQL is treating this as a preventative measure against this class of problem.
