----------------------------------------
Summary: Schema description escape scan reads past end of line
Key: DIRAPI-465
URL: https://issues.apache.org/jira/browse/DIRAPI-465
Project: Directory Client API
Issue Type: Bug
Affects Versions: 2.1.8
Reporter: Emmanuel Lécharny
Fix For: 2.1.9
A hostile server (or pre-TLS *MITM*) returns a _subschema_ entry whose
_attributeTypes_ value is "_( 1.1 DESC 'x\\5" (line ends two characters after
the backslash)_.
The client calls _loadSchema()_, _getQDString_'s scan calls _isEscape_ at the
backslash, _charAt(index+2)_ is past end-of-line, and *SIOOBE* propagates
uncaught — the application's _catch(LdapException)_ does not fire and the
thread dies
