Detail
| The pygresql module 3.8.1 and 4.0 for Python does not properly support the PQescapeStringConn function, which might allow remote attackers to leverage escaping issues involving multibyte character encodings. |

| Title: | DSA-1911-1 pygresql -- missing escape function | ||
| Description: | 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, this problem has been fixed in version 1:3.8.1-3+lenny1. For the oldstable distribution, this problem has been fixed in version 1:3.8.1-1etch2. For the testing distribution and the unstable distribution, this problem has been fixed in version 1:4.0-1. We recommend that you upgrade your pygresql packages. | ||

| Title: | USN-870-1 -- pygresql vulnerability | ||
| Description: | Steffen Joeris discovered that PyGreSQL 3.8 did not use PostgreSQL�s safe string and bytea functions in its own escaping functions. As a result, applications written to use PyGreSQL�s escaping functions are vulnerable to SQL injections when processing certain multi-byte character sequences. Because the safe functions require a database connection, to maintain backwards compatibility, pg.escape_string and pg.escape_bytea are still available, but applications will have to be adjusted to use the new pyobj.escape_string and pyobj.escape_bytea functions. For example, code containing: import pg connection = pg.connect escaped = pg.escape_string should be adjusted to use: import pg connection = pg.connect escaped = connection.escape_string | ||
