Subject: [PATCH] DSC parser - validate parameters
|
|
|
|
Bug #697190 ".initialize_dsc_parser doesn't validate the parameter is a dict type before using it."
|
|
|
|
Regardless of any security implications, its simply wrong for a PostScript
|
|
operator not to validate its parameter(s).
|
|
|
|
No differences expected.
